To save you time, the best purifiers are:
1. BlueAir
2. Germ Guardian
3. DIY
4. Honeywell
5. Dyson
6. Levoit
I came to the comments for this. Thank you!
@@Charmingpreppylife he’s wrong though. He might have meant to say “the purifiers with the highest CADR are...” but what’s actually BEST depends on what people need, and obviously we don’t all need the highest CADR.
The Levoit they used was literally Levoit's shittiest model, meant to sit on a desk next to someone because it only reaches 1 foot around it, it is not not even meant to do an entire room. It doesn't even have a carbon filter. Dyson has no excuse that is $800. The $250 Levoit model is much better. I went from anaphylaxis from airborne allergens to no incidents since I have had it. It is unfair they used the shittiest model to tarnish their reputation. That model was $60 before the pandemic too, I know because I considered it and decided to get one with an actual HEPA filter instead. This Marketplace was extremely misleading and full of misinformation. I am actually extremely disappointed in them for this poor research. They didn't even mention the difference between filter types and how they work. It was such lazy work.
Thank you!
@@Pollencakes It's insane, that this filter was only 60$ before and I assume dyson always was about 800$.
Poor Dyson engineer. They clearly cut up his responses. It would have been nice to know what his explanation was since they were the only company willing to talk.
exactly. Now we know why companies don't talk with CBC News, they cut their full explanations into tiny sentences.
I think you're right. All they went on about, and rebutted by Dyson was the CADR metric. So it can filter out X amount of air but now how effective it was afterwards. I'm sure if you grabbed a faster flowing box fan and strapped the same furnace filter to it, it too would push out even higher CADR numbers. That filter can/is only filtering so much before it is full/clogged and it's CADR number will significantly drop (but will actually filter better).
In the PHD's test lab, they measured the volume of air that was able to be filtered. What about information on PPM of the incense smoke after say 1, 2 hours for each filter? Wouldn't that tell you how effective the filter was?
@@maxwellkeeling3781 Exactly, there is a LOT to filtering air and movement, I learned this with carbon scrubbers air filters and sizes and speed and a lot of research. It's more than people think. Move the air too fast and it doesn't get a chance to be filtered through the carbon, it flows "over/past it". Too slow though and it is not effective enough, like they said. There is a "sweet spot" where you get a balance of both effective filtering and air movement. And yeah, as filters get clogged the airspeed will drop, but the filtering goes up. This is what they found with masks and Covid.
That extended mask usage, while not good ultimately, was good up to a point in the sense that the filtering efficacy went up with them. Simple cotton jumped almost 10% higher the longer you wore it. Moisture buildup from breathing is likely what was narrowing the tiny openings and making it filter a bit better. Of course the tipping point the other way, isn't far behind (so dirty it needs cleaning or discarding), but there again is that sweet spot where it's great. It's a finite thing, a delicate balancing act. Same with cars, efficiency and durability and power. You gotta be insanely efficient nowadays, but also have performance and longevity too, you have to split down the middle somewhere and find the happy medium between all of them.
Considering the price point of their devices, they're almost OBLIGATED to release some kind of statement ...
@@kizersosei4919 agreed
My take away is that, like they mentioned early on in the video, all of them uses HEPA filters so what matters most is the airflow that these purifiers generate through the filters. The reason why that DIY filter works so well is probably the fact its a HUGE fan.
Yes and no. HEPA filter is not the only filter used in air purifiers. A lot of them have carbon filters as well, those get rid of smells and chemicals (HEPA gets rid of only particles). Dyson has a rather thick carbon filter with a lot of carbon granules Blueair has a thin sponge with a bit of carbon inside, so technically they both can say "we have carbon filtration" but their performance and longevity will be different.
The other part why Dyson is so expensive is their bladeless fan technology (the filter doubles as a cool and hot air fan), and a ton of sensors and smart technology bits and bots (you can get air quality reading, control purifier from the app, set timer etc).
So yes for getting rid of particles alone, big fan, big HEPA filter, thats all you need, and that blueair 211/221 is perfect for it. If you want to get rid of particles and smells look for a purifier with a carbon filter full of granules, not the sponge ones. The other stuff like air quality sensors, auto mode and smart device functionality depends on your preference. For example blueair has auto-start so you can use a a smart electric socket or a socket with a timer to make it work on a schedule or control it via app.
BTW. Carbon filters are dirt cheap and easy to made, so it is disgrace that there aren't that many air purifiers with decent carbon filters!
Saing that Dyson is blade less fan is misleading. inside there is regular fan. This fan just redirect the air steam in some "fancy" and vey inefficient way. Beside the form and high price there is nothing good about this fan.
@@miroslawkaras7710 I agree on this. The name is silly. Still it is their patented technology and they are selling those "bladeles" fans for high price. So it's natural that they ask pretty penny for having it on air purifier.
Not many purifiers doubles as fans so there is some value there.
I'm not fan boying for Dyson, I just didn't like how they pounced on Dyson in this report. They simply sell a premium product with different features. Personally I wouldn't buy it, but dog piling on them because they do not filter as fast as other air purifiers is a bit weird.
@@pingwingugu5 At the same price, you can get Austin Air Purifier that contains 12 lbs of activated carbons. Dyson is only good when you use all of its functions - heat, fan, and purifier. Otherwise, you will be better off buying them separately.
@@GBR9794 if you can fit 3 separate devices in your flat then sure ;-)
I actually respect Dyson more now, given that they agreed to interview and the guy raised excellent points too.
not me , he is a sham , Dyson is for fools.
Excellent points like what?
@@x-0-x-0 rate of clean air flow is not the only metric. Stuff like design, longevity, energy consumption and technology matter too.
You respect a company that is outrageously overpriced and has the worst performance of cleaning the air with their air purifier? SO you respect fraudsters?
@@honprarules that's ridiculous. They were measuring how much the air cleaners filter the air you breathe. Longevity, energy consumption was irrelevant. The technology matters the most - the technology of an air cleaner needs to be good enough to clean the air! The Dyson was terrible.
I rate Dyson for sending someone to talk about this. Too many companies hideaway. Great episode!
So true
He was dodging the question though; I did not hear what other important metrics they are focusing on instead of CADR and why...
@@jinwang562 I find this video less informing because other big important issues are , how loud is the machine? Dyson is the best for that for example due to its efficient motor. Other than that how much power it needs to run at that CADR. I was expecting a bit more data than just cadr
@@jinwang562 he wasn’t dodging they edited that interview. He’s right that just using that one metric is not a fair representation of the field. They also have fans that just do air purification without the heat function etc that would have made for a much better comparison.
@@ucyberwolf It really doesn’t make sense why they decided to not use the model that only does air purification. It is cheaper than the one they tested and it is designed for larger airflow. It’s misleading at best and I question if it was intentional to make this more sensationalized. Poor test, you could have done much better.
Kudos to Dyson for appearing on camera.
Was that guy even a representative? He looks like the actual engineer.
Right? The guy made good points and I respect Dyson more for it now.
Kudos to Dyson. She kinda annoyed me when he said purifying wasn't the main metric and she says researches says it is. Clearly he was saying purifying the air was a bonus feature on their fan+heater.
Exactement 💪🤣
@@BrickMediaStudios Even more kudos, sent the person who knows the product inside out, not someone who is there to read lines
I applaud Dyson for coming on camera! I’ve seen so many of these where the companies decline that opportunity. Regardless of the outcome, I’m proud of Dyson!
The host seems so rude and aggressive when questioning the engineer from Dyson. Sure, it can catch the eyeballs when the most expensive Dyson product failed the CADR test, but CADR doesn't define how clean the air is.
I can definitely confirm that Dyson sales people will just show you their product but will never force you to buy. They themselves have told me to research it and if we think it's worth buying then we can always come back.
This is true.
the bible says God created the Earth in 7 days. Therefore it is true.
thanks dyson marketing troll
That's probably because they can't actually make any solid claims about the quality of their products.
You mean Dyson salespeople don't carry sidearms?
That one family with the mom coughing in the basement should consider getting tested for radon.
Air quality guy really should have checked for radon. But I suppose that, for this show, it's irrelevant. You don't fix radon with air purifiers.
radon is a silent killer
Radon is not rad
@@contournut5726 how do you eliminate radon?
@@grod805 Radon is naturally occurring in soil and can enter a home through its foundation. Usually radon levels are higher in parts of the house closest to the ground such as basements. Typically, it is eliminated by venting air from under the foundation to the outdoors. This is done by installing a pipe that extends from under the foundation to outside the house, and installing an appropriate fan that draws this air outdoors.

10:04 what is CADR
❤
Dyson is the only one that offers cooling + heating. Its not solely designed for air purification. There's a premium cost to have that all in one device instead of three. If you live in a small space, the fan+heat+air purification in one sleek package from a company that makes insanely dependable products could be worth that premium. Kudos to Dyson for showing up!
it doesn't heat... but okay
@@seansapir1 it literally does
You can buy a compact space heater for $20
100%.
I bought this mainly for the heating option.
I got a bonus cooler and purifier with it. 👍 I can't complain about that.
Plus it looks way cooler.
One cannot argue with someone that bought the product as they will take it as a personal offense unfortunately 🤥🙄
🤣Poor Dave from Dyson. I feel that his in depth explanation was edited. Made him look a right plum.
Now we know why companies don't talk with CBC News, they cut their full explanations into tiny sentences.
marketplace always does this, to make their original premise appear to work. They love bashing any popular product with their own limited "tests". Cant stand this show for that reason, but i was curious to see if they had cleaned up their act any. NOPE.
It doesn't appear edited, and it seems pretty in line with Dyson products: Style at the expense of some functionality.
Aren't plums supposed to be ripe?
Lol
One more thing everyone should look for is availability and cost of replacement filters. This will make all of the difference if you intend to use the device longer.
Also how loud it is and how much power it uses.
Agreed. It has been impossible to find replacement prefilters like the one in the Honeywell I spent hundreds of dollars on.
I get my filters on amazon great pricing for half the price
@@CheapSushi true, the dyson uses 2250 Watts power!
@@pmabrouk I have a thirty year old honeywell true hepa. I found new old stock filters and pre filters on ebay.
This could have been a great study. However it was flawed from the beginning. They're not testing Apple to Apple's comparison. The Honeywell that was tested as well as the germ guardian are not comparable to blue air. They're much smaller they're purifiers. They should have used the Honeywell HPA300 which is more comparable to blue air. It's much larger and meant for bigger rooms. You can't compare small room air purifiers with big room purifiers. The CADR ratings will of course be different because they're meant for different size rooms. I can't believe this is actually gotten so many views.
I would give this video an 8 out of 10...they did a good job and included several different perspectives. However, they never mention the size of the area they tested in comparison to the room size recommendations for each product. Naturally the smaller filter will get a lower CADR in a bigger room. Also, I would like to know why particulate count is important and if mineral particulates for example are even bad for us or could even be good for us?? Lastly, as a Certified Mold Inspector myself, I know that a lot more goes into the mold analysis than just a visual inspection and air quality testing. The lab results only show a snapshot of the mold count in that exact time and location. I would be willing to bet that the lady with the mold in her home actually has a serious mold problem and needs treatment.
Alto they don't mention that they used a fan to agitate the air at 11:23
Agreed my friend, I believe they didn't want to completely destroy the old lady on the show about her serious mold problem, so I'm assuming that guy took her aside and warned her of the very problematic mold that she needs to get rid of.
She willingly volunteered obviously, so they probably gave her that much.
Literally. These test they ran halfway mean nothing. Wouldn’t even give it an 8, prolly closer to a 6
Exactly what I was thinking. Its not an apple to apple comparison. They should test the purifiers based on thier capacity rating
I really don't understand your reasonning nor any of the answerer's. The metric given is in m3/hr. It doesn't deppend on the size of the room. A 60m3/hr purifier would clean up a 60m3 room in an hour but a 120m3/hour would do so in half the time. Or am i missing something ?
The professor looks exactly what a professor should be.
Lol that's my prof and he tells and energy related pun before every lecture
Batman
Yeah
He came out of the same mold as bernie sanders.
he looks like a Bruce Banner
I think you should have compared purifiers with more or less the same "room space" on their packaging. Of course, the Levoit loses, it's tiny. That's how physics works.
Dyson seems like a respectable company to have at least sent a representative to explain.
There's a problem here: The CADR is important, but it doesn't tell you how thoroughly it filters the air. Some of
the purifiers shown had carbon filters that absorb gases and fumes, among other things that pass through HEPA filters like the Filtrete too easily. CADR is an airflow metric. You need both good airflow and proper filtration
I this just has to do with the type of filters in them
They said it doesn’t even matter how good the filter is if it would not even pass through the filter due to low airflow
CADR is a measure for the clean air output. It considers both air flow and filter efficiency.
Those carbon filters are more gimmick than actually helpful. Yes, they can remove gases, but not for very long. Unless you are changing them out very frequently .... it's snake oil.
@@financialchimes4546 except clean air means different to different companies. I can't ever consider a purifier with no UVC for killing germs should be considered giving out "clean air". On top of that the more layers filters being present obviously drastically drops CADR. The blueair ones don't have all the filters hence the CADR is high. By that logic, the lower CADR would be better lol. The entire metric is ultra bogus gimmick to start with.
Dyson has a point tho -- can't really base everything off of one metric...I was expecting a more thorough answer from these videos but they're a bit misleading. Too many variables not accounted for and it doesn't seem like they had a standard for picking which devices from each brand to test. Some might have been for smaller spaces, therefore .. the glaring results. Ah...
Exactly! They were just measuring air flow. Maybe they got better air flow in the model with the fan taped to the filter because the air wasn't properly passing through the filter. Lol it looks like they literally put it together with masking tape.
Exactly what I was thinking. They just measuring the volume of the air. Obviously the bigger the fan, the bigger the airflow generally speaking
They also use a fan to agitate the air in the test room 11:23, but they never mention anything about it ;), guess why.
I bet Jeff doesn't fart because that would be too much particles in the air for him.
He was actually born with a mask.
Came to the comments for this! LOL
If you’ve never used an air filter these are great. czcams.com/users/postUgkx_dppjvjF8BYEmPSDTcgCUdRsgWYLXNHN I ended up with three after starting out with one. The noise level depends on the 1-3 settings with how hard you want the machine to work. You can also upgrade the filters and get one better for pet hair and smells which is a must have in my home. I noticed the air seemed lighter and easier to breathe when running the machine for the first time. Works great every time. Highly recommended!
To be fair, I feel like you should have compared air purifiers rated for equivalent size spaces. For example the larger Honeywell 300 is more closely matched to the Blueair you tested and the CADR of that model is about the same as the BlueAir. Also make sure the Blueair model you select used true HEPA filtration as the Honeywell does. Some Blueair models use HEPA but not all do. In addition, the term true HEPA is a standard defined by government regulation. “HEPA Silent” and other “ HEPA-like” filters, there is no defined standard.
Yes that why I’m saying they all for different room size
The blueair 211+ they tested in this video doesn't use hepa. In fact none of blueair's products use true hepa filters.
Not only that. The Blueair model they tested was a large room air purifier. Many of the others were not. It is interesting they compare the tiny Levoit LVH132 "Personal" desk purifier against the other larger units. They could have at least used the Levoit LV-PUR131 or Core 600S. While they are at it they should of had the popular Winix 5500-2 in there. All of those units have a separate activated charcoal filter for harmful fumes and also have a true HEPA filter. I swear this test must have been ran by Blueair
@@nano411 you're spreading misinformation. Classic series and above use true hepa filters. To the OP, HEPA Silent is only defined by noise(fan speed), not filtration capabilities. HEPA is a standard for the filter, not fan speed. In any case, HEPA Silent doesn't mean anything. It's just a low setting for the fan. The Blue Air Classic and above are are true HEPA filters.
@@nano411 that is true, I’m not sure how much it matters though. I use levoit myself, but blue air proprietary filter tech is quite good, it’s been independently tested and shown as such. Hepa is a proven technology that gives a great deal of comfort as a marketing term as if your filter is hepa certified and has good cadr, you know it works. Blue airs proprietary tech is quieter and does consume significantly less power. I suspect off
The shelf hepa tech did not meet their requirements for power or noise levels.
Since there was such serious claim made about humidifiers - do those please. There are brands that claims that they filter water from minerals and therefore regular water could be used
Right after he said that, I was like....what if you use Brita filter water instead of tap? 🤔🤔
Not everyone can afford to buy distilled water to constantly refill their humidifier
Update: Emailed the expert and unfortunately Brita doesn't do much in terms of getting rid of minerals/particles for usage in a humidifier.
Dissolved minerals would need an ion exchanger, not a filter.
@@knd44 you could buy a stovetop distillation apparatus - a still - and make your own. Then use it to make some liquor to recoup what you spent on it!
@Andrew Demchyshyn I found his claim to be somewhat agitating. It appears he was using an ultrasonic humidifier with tap water. Ultrasonic humidifiers are supposed to be used with distilled water which will have little to no particulates. There are other humidifier types on the market. Additionally, the amount of particulates in the air when measured immediately beside an improperly used ultrasonic humidifier do not necessarily represent the amount of particulates which will be suspended and stay in the air. It's much more complicated than he stated.
Edit: My @ didn't work for whatever reason.
You used the smallest version of the levoit in comparison with full room purifiers. Levoit comes up recommended often year over year for decent air quality.
I think what should have been mentioned about the Dyson is the fact this it’s also a fan so it literally pushes and circulates air around a room. A lot of air purifiers on the market create a pocket of clean air around them and they basically keep cleaning the same air over and over because there is nothing pushing that air across the room. So if you do buy an air purifier sans fan, you should also buy a separate fan that keeps the air in your room moving.
Exactly. I think he mentioned air "projection" at some point. CADR doesn't measure that. It's too bad he didn't have more time to touch on the subject
If the purifier blows the cleaned air in a different direction from which it is pulling from, it is in effect, circulating the air in the room. Blue Air has the highest CADR and uses this design in all of its models.
@@WHERESSS Have you experienced the air projection from most air purifiers? They project at a very low velocity. That air doesn't travel far before being recirculated through the purifier.
@@meboz67 Yes. Blue Air fans are strong. That's what the CADR is, effectively. Without a strong fan with high airflow it is impossible to achieve a high CADR.
much cheaper to by a fan plus BlueAir
I have Large Levoit purifier in pet room and the one presented here in bedroom. Both are quiet and works great. Helping with my allergy and asthma as well as not letting in stench from my smoking neighbours. Definitely match size of your purifier not only with room size but also considering how you gonna use the room.
what type of levoit? vital 100 or P350?
yeah I love my levoit
Is this true for the test you did? I was pretty underwhelmed. I wanted to know like reductions in different levels and percentages. CADR seems a pretty limited and basic test, surely there is more to an air purifier. how does it affect mold levels, VOCs and so on. Does room size matter. It seems that them levoit is for small rooms and the blueair for large rooms so of course it would be more powerful? Simple research:
"For all of their advantages, CADR ratings don’t tell you everything about an air purifier. One of the biggest CADR limitations is the fact that the test does not include gases, odors or VOCs. These non-particulate contaminants are very common in home air and can be targeted by air purifiers that use carbon filters. Many air purifiers that carry CADR ratings use HEPA as well as carbon filters. When these air purifiers are submitted to the CADR test, only one part of their filtering capabilities is actually being measured. So, if gaseous contaminants are part of your home air quality concerns, a CADR test should not be the only metric you use in picking out an air purifier.
Another drawback of the CADR test is that it only tests air purifiers on their highest settings. While this is an understandable standard for the test, it can inflate the unit’s efficiency in a buyer’s mind. If you are buying a bedroom air purifier, for example, it’s fairly unlikely that you would run it on its highest setting while you’re sleeping due to noise concerns. This being the case, the air purifier you buy would not be performing as efficiently as it was under the conditions of the CADR test. This fact is important to keep in mind when looking at the CADR ratings of air purifiers you’re considering.
Finally, the CADR test only shows how an air purifier will work within a very limited period of time. While the 25-minute test allows the unit to cycle a significant amount of air through, it can’t tell you how it will perform after weeks or months of continuous use. As HEPA filters absorb particles from the air, they naturally experience slight declines in efficiency. While this shouldn’t be a serious problem if you’re changing your filters on the manufacturer’s recommended schedule, it is worth noting that the clean air delivery rate of a purifier with a brand-new filter operating for only 25 minutes will be higher than that of the same purifier with a filter that has been absorbing particles for several months.
"
Did Dave from Dyson give you the rest of his explanations that they probably edited out? Because what you've said sounds pretty much like an elaboration of his "we don't think that the measure of air purifying capacity is the only thing that's important when it comes to appraising air purifying capacity" line. To be clear, I'm not necessarily disagreeing with you or Dave, because nothing can ever be distilled down into a single all-encompasing number without at least partially sacrificing nuance or compromising situational variance, but the underlying issue that this piece was trying to highlight is that customer expectations in regards to these air filters are not necessarily matching up with developer intentions (if we're assuming good faith rather than corporate greed), which among other reasons seems be greatly influenced by imprecise and uninformative product claims on the box or in ads.
This mismatch between company and consumer is a fault and responsibility of the company, not the consumer, who should be provided with adequate and relevant information about the product and its expected use cases so that they can compare the product with others and thereby make a decision. It's all well and good for Dave to encourage customers to do their own research, particularly for a company like Dyson whose products are priced more than high enough that most of their customers are probably capable of actually conducting such research or have enough money that they don't actually care. But a great many consumers are not actually capable of successfully undertaking the kinds of product research that Dave and many other companies seem to expect (or hide behind), which is why we have consumer protection laws that place the responsibility for researching and communicating information about a given product onto the company, not the consumer, or that at least prevent companies from making claims or representations that they can't reliably demonstrate.
Like, I'm sure that the legal department at Dyson and all those other companies have scrutinised every word of those product claims and ensured that none of it actually breaches the letter of the law regarding what claims they can and can't make, or how they must represent them, but based on this video it seems like many of these companies are less interested with actually helping their customers make informed decisions about their products (which you'd hope they trust enough to be appealing when portrayed truthfully and saliently) and more interested in telling customers (or not telling them) whatever is necessary and legal in order to goad them into buying the product. Obviously, I don't naively believe that this practice is limited to the air filtration industry or that it's a remotely new practice, but it's still disappointing to see nonetheless.
thanks for your detailed response. Very good critique!
The reason they don’t test it is because hepa is hepa, it’s already a known quantity. So cadr really is the only difference, other then looks and features. Levoit sells specific filters for VOC/PET/Standard Hepa, there are very few differences between hepa filters
B-roll must be so much simpler with face masks “yeah just nod at each other a bit...”
I had a multi-gas, ammonia, smoke/HEPA,...air filter systems. I had a positive air pressure system. With all the systems going full blast they could still be overwhelmed. If the pollution was coming from the wrong direction that positive air pressure system would suck it in. (You needed the premium positive pressure system with a chemical filter that cost 20K more. I didn't have it.) I had a $400 air filter in the HVAC system. What the system did do was clear the pollution faster.
The blue air filter is so massive...built for 540 sqft space.... Compared to the smallest Levoit 160 sqft space Good job Marketplace 😊😊😉 what a way to compare. Ive seen levoit's have bigger models .

It would be nice if the reporter would have spoke about the ongoing costs of replacing the expensive HEPA filters. I did a cost analysis in a big box store on a few of their popular brands and the filters can exceed the cost of a unit in 12 months with some brands.

Blue air wins!
I bought a smaller model blueair a year ago after much god level research and price considerations and I have been VERY happy with the results. The red light just came on showing that a new filter is needed and considering it’s just been in a bedroom with a none smoker and I’m on the west coast of Ireland right next to the Atlantic air, not much cleaner than that,I was horrified to see the colour and hence how much particulate material it has filtered. Also super quiet on low and moves massive amounts of air on high.
Thanks for sharing! Good things to know. I just tested an Alen 45i and I would agree that a high enough CADR is an underestimated feature.
CADR measures the rate of clean air delivered. So obviously the bigger the device the higher this will be. This test isnt exactly fair based on varying sizes of the devices.
While I don't disagree, I think the comparisons are all very valid. I think, instead of being compared to raw CADR, however, I think the MORE valuable measurement would CADR/Dollar
@@mr.bennett108 im not saying the tests werent valid. I just wish they had chosen models that were more in competition with each other to make things more fair. Right now its like having a civic, corolla and bmw 335 going up against each other to see which is the better driving car.
Yep pretty much. Also Dyson have a naturally low CADR due to its design
Not to mention they didn't test for VOCs which HEPA only filters will not filter. Dyson was entirely correct that CADR while important isn't the only metric, additionally a finer filter that filters smaller particles will have more resistance for any given surface area. They didn't strap a HEPA filter to the box fan so the measured CADR is immediately not comparable to any of the other air filters (though the filter used was still good enough to trap most allergens like pollen and dander.) Additionally they did not disclose the efficacy in reducing the particle counts, what good is a high CADR if the filter is 70% efficient vs 90% efficient on a model with lower CADR. There's too much nuance into what makes a good filter to cram into a 20 min video that needs to tell a story.
I feel marketplace's quality has been on a sharp decline for years in their chasing of broader audiences by americanising the editing style and removing all semblance of actual information and quantifiable testing.
While you survey homes, you never really touch on apartments. I think that that that is a whole different ballgame, as you don’t have as much “control” over air circulation.... you can’t change filters in your furnace.
You need a whole different show on apartment air quality!
Stay safe, stay sane, be well
One of them lived in an apartment but yeah air quality is really bad in apartment buildings, even more so if they have laundry facilities, are pet friendly and allow smokers indoors.
Especially with neighbors who live in same building and smoke cigarettes several times a day and it's obvious someone is smoking near the front gate and it blows to our apartment in the back of the building (my neighbors are usually seen smoking outside on their porch or our outdoor entrance area facing the street)
Edit: I am in the west coast of US
So true! How many people on Toronto and Vancouver can afford single detached homes? Please think about us poor millennials.
@@sleepy.bunneh : it is not just your group of people. People on fixed incomes and minimum wage jobs also cannot afford to buy homes in major urban centres. Condos are the alternative, but they are just apartments that you own, and still require a monthly payment fee.
for a real world view, my son started suffering from asthma when in our front room, the cause was most likely the dog or the vintage sofa. We live by a busy road, so opening the window isnt an option, after a bit of research the cheapest option was to get an air cleaner and we bought a Blue air 411 (the smaller version of the one they tested here) it was rated for a 15sqm room, so more than adequate for the front room. the difference it made was noticeable within about an hour (the air smelt cleaner) and within 2 days my sons symptoms were massively reduced, he still gets asthma it if he jumps on the sofa, which we need to replace all the filling on. but for me its been very conclusive how effective the air cleaner we bought is.
Misleading.
They focus on a single metric, CADR, but don't go into detail on the differing levels of performance required to filter out diverse types of pollution. Plenty of tests will show you most APs will filter out particles quite well, including the Dyson. They all feature HEPA filters and will do an excellent job. But what about VOCs? NoX? Benzene? Formaldehyde? For that you need at least a chunk of activated carbon filtration, and potentially other techniques. Lab tests may show Blueair doing a decent job of filtering particles with its high CADR rate, but they've also not historically done so well with VOCs compared to -say- IQAir.
Bottom line: one metric of air purification performance isn't good enough. The rep from Dyson was trying to explain this, but the way they've edited up his response doesn't really seem to highlight the full reply he might have been trying to give.
Why did you compare a compact Levoit to the larger models of other brands. The Levoit LV-H133 has a CADR of 400cm/hr. and would have been well rated. Apples to oranges?
Yeah, they should have test it in s small room and see if it was effective rather than testinh it in large room.
I wish USA do This kind a shows who check everything everyay product
They used to. Now they’re paid NOT to investigate...

The Dyson fan is fantastic. For those of us who can't sleep with the sound of a fan, it is your go to.
I can agree to this
Interesting review. What’s weird to me is the co2 level was measured in the beginning, but none of the fans will change that. people just should open the windows every now and then. 😅
and i just checked the lasted PH04 model from Dyson. It has now a CADR of 1260 m3/h (page says 350l/s). Is that correct? Would be the new winner.
We own two Dysons, not the specific model listed but the same look with a tower(TP02). We purchased them for the air movement, the purifying is just a bonus. I wish they would have reviewed Molekule and Air Doctor. I own an Air Doctor as well and can attest that yesterday after having the back door open we were flooded with irritants from someone burning/cooking nearby. I was having horrific allergies. We turned on the air doctor and it most certainly did clean the air as I was able to breathe much better after a few minutes.
I tried researching the Molekule some time back. I just recently tested an Alen 45i purifier. The Molekule distinguishes itself with the use of UV technology. The second expert with the glasses said that UV technology is not worth it. He said that the amount of UV used is too low to be effective.
Interesting. The filters are something to factor in too- the Dyson and blue air filters are €60 each and need replacing every 6 months depending on how much they filter out. We have a de Longhi- about €370 when I bought it. But no idea how it compares! But Dyson filters are out of stock right now.
I think they don’t compare correctly. They should compare how many square feet room each purifier. They just picked randomly
I love my Dyson hiot and cool. I have the prev gen from Costco too. Helps a lot in smaller places I think and has extra options. The more substantial options the better
It's not really practical to say 'don't use humidifiers'. Air gets very dry in winter which can cause other health problems. I use an evaporative humidifier (works like a swamp cooler, blowing air through a wick filter that draws water from the reservoir). Very little of the dissolved minerals ends up in the air this way. You don't need to have it in your bedroom, either--you should be humidifying the whole home. The one watch-out is to replace the wick regularly and use a biocidal additive to prevent growth on the wick.
A tray of water would be a better choice at a low cost of entry. With near zero chance eof failure unless you flip it over.
@@lot10101 I can evaporate 3+ gallons per day with a humidifier. A tray of water isn't going to get the job done. If you are too cheap to get a humidifier, use a bucket as a reservoir, hang a towel dangling into the bucket, and use a box fan to blow over the towel. You need surface area and air flow to evaporate a lot of water. You can even get the box fan to pull double duty and strap a filter on it to filter your air at the same time!
A bucket of water with an aquarium heater works well too
That's why they said use distilled water or a steam humidifier
@@andrew20146 lol... I live in the tropics and have no need for a humidifier.
Interesting that you know me better than me.
Hi again. Also, I am wondering how come we didn't hear back regarding how the homes faired in terms of VOCs and formaldehyde levels? (At the beginning of the episode it said they were testing for them. I watched the entire episode waiting to hear back on the results of those, LOL.) Or were those the "particles" they were referring to that came from the essential oil diffuser, cooking, and humidifier?? There were many threats to clean air from VOCs and formaldehyde they did not mention such as scented laundry products and candles or new furniture and flooring just to name a few.
Yea, me too. I was waiting to get more in depth details on other VOCs.
I own a Dyson (TP02) it cleans the air slowly, takes about 2 hours on auto mode when the air quality is really poor. On the bright side you can set a schedule, night mode, check air quality, humidity, and temperature from inside & outside with the app.
I also purchased the Blue Air 211 for the living room but started smelling sour within a week so I returned it, and the purchase a Winix air purifier.
This was awesome so informative and learned so much especially about the humidifier, and the oil diffuser. It’s so true these things are seen as a wellness thing but science shows differently
my family has never had any issues with diffusers but certain oils aren’t recommended
For cats. I can also see how diffusers might not be the best for oxygen compromised people. However I can attest to how great Essential oils are for your health when mixing with carrier oils.
That opening frys my brain. It's so hard to listen to when you've know the song inside out from the day it was released. Great tutorial.
That Asian lady didn’t waste a second asking for the dyson lol.
Lmao
she knew it was the most expensive
The reporter savagely tackled the Dyson engineer who struggled to give solid answers to her questions.
This is perfect! I think I need to get one but overwhelmed by so many brands out there.
I have the box fan setup. It's great and all but the thing is as loud as aircraft when at high mode. Low mode is better but still LOUD.
Yep, I've been doing this since University of Michigan released a video about it like 9 years ago, and same thing and my only complaint has always been the noise. Also: quick tip make sure to check the corners of your fan! hold some toilet paper to the corners, you'll see they're actually sucking in! Put some tape over it to fix it. I try to tell everyone who does the filter-technique this!
I'm surprised the Winix models weren't tested.
SO VERY HELPFUL! I have been researching my options for my apartment to help deal with neighbors smoke fumes and to overall clean my air. Thank you
I'm so grateful for the meaningful work CBC marketplace is doing! You're doing Canada proud!!!
they fooled everyone, the reportage is highly misleading, they used another fan to agitate the the air in the test room and they never explained how the test was performed. 11:23, you've been fooled.
I have that Dyson fan. It works so well I bought a second one. The heat function is amazing and also the sensing works very well.
It came in handy during a power outage that lasted a few days in winter and ran perfectly on a back up generator
Me as well and i smoke in the room from a bong and it cleans that smoke quick
A heater that heats. What'll they think of next!
The problem for Dyson is their tiny little fans are very poor at shifting air.
Got the same one, and seeing how well it works i think it really is unfair to just take count of the CADR
I literally just recieved my Levoit Core 300 from Amazon today so it was a bit of a scare to see this AFTER my purchase. However, I feel good knowing I bought it only for the bedroom and it's rated at 215ft², 135+ CADR which for my roughly 10'x14' bedroom should be sufficient. I also just bought a basic humidifier off Amazon and have been using it for the past few days and ONLY with distilled water which again makes a difference. I'm shocked by the Dyson results, we have one of the first generation vacuums and it's still working although it's probably on the way out after more than 10 years of good use. Good to know this stuff, good job CBC.
I'm wondering if they tested it in a to large of a room. By the looks of it in the video it might have been to big of a space.
@@XDonlyone Yeah as much as it was an informative segment, I feel that the machines got a bad rap for being "underpowered". For the expensive Dyson I can understand the disappointment; but the cheaper, smaller units aren't designed for anything other than small bedrooms, which is what I use mine for. You don't need 500+CFM for a bedroom.
@@DABlinxz i bought the Levoit H13 a few months ago for my bedroom and I no longer wake up congested and I don't know how to explain it but the air just feels light and clean to breath in. So it's working more then fine for me.
We use that one in our bathroom. Been using it for at least 2 years. Does really well in a small room.
@@XDonlyone I'm saving a fortune in sinus medicine.
Dyson air purifiers are excellent. They spend millions on R&D, have thousands of engineers at their HQ just up the road from me. I trust their engineers more over a TV new channels 3 “experts”
Proud Blue Air 211 owner and it works great!
I have a Levoit in a different style (horizontal rather than vertical if it makes sense) and I find it pretty decent where a litterbox is. It's just very loud.
17:00 - Watch the technology connections video on humidifiers. It's because of the type of humidifier. Evaporative humidifiers don't throw nearly as many particles, minerals get left behind in a replaceable wick.
is dysons humidifier good?
@@randomrazr Dyson anything is not good, especially for the money.
Would like to know best way to moisturize the air if humidifiers are not recommended…
The blue air brand uses electrostatic technology which is why it's so efficient with it's air flow. But it also generates very small amounts of ozone, and can actually reduce the ozone in the room. If they're CARB certified you should be fine unless you are super sensitive to ozone.
Electrostatic = ionizer, very controversial if negative ions helps or hinders your health. I got the 211+ Auto today but I wish I did more research on this. Customer service at Blueair does not seem to professional so far.
The Blueair is CARB certified.
I did my little research back when trying to buy air purifier. The result same, blue air and I am happy this video confirms it.
Evaporative humidifiers should be fine, the issue are ultrasonic ones with anything by pure water (distilled, RO)
Also if you have mould issues it is a good chance you need a de humidifier
What about cool mist humidifier?
It would be great to know the ongoing replacement filter costs.
The thing about the questioning they are pursuing with Dyson is that the measurement they use is how much air they filter and not how well they filter the air, or how good their filters are.
bought a winix.simple and does the job.Dyson looks amazing.
I was literally just about to buy the dyson cold hot purifier....this was an excellent unbiased episode. Great job 👏
I have the Dyson pure cool desk fan (DP04). It's a great purifier. Highly recommend. It has a higher flow rate than the HP04 pictured in this video. But like the Dyson engineer said, CADR is only one metric of many. I got my purifier for my dog allergies (we adopted a shedding dog). Haven't had to take my allergy medication since I purchased the purifier!
I have a Dyson hot / cool. I'm heavily asthmatic, and drastically reduced my inhaler use. Easily by 90%.
I also like it's a heater and I can use it in the winer. And that it has a wifi transmitter; I can program it from my phone and view the analytics.
Also that it doesn't look horrible and sound like a jet engine. When the other ones can do that too, I will buy. 👍
Nothing is ever unbiased. They are always trying to shock for the views.
You can't compare products with different features, as if they are the same product.
They probably called Dyson and said they have technical questions. Then turned the engineer into a salesman on the spot. I'd like to see the whole interview.
When you are buying Dyson you are not just buying air filter system. Hot, cool, air filter, internet app control, design, quality. All these cost money. Sometime these filter system don’t even a proper timer or remote.
I would do that DIY filter box fan for my basement, not for my bedroom.
I don’t think it matter much air a device can clean per hour if it can not move around to create even more air flow. You want it to get the corner as well.
I hear yall, ...its doesn't just do one thing, it does several things with style..
I have a dyson v10, best vacume I've ever used.
@@little.tricks you re the only one with disstisfaction
Does anyone know whether it’d help to put two filters on the back of the fan for the DYI?
David from Dyson is right . Volume rate is not the only metric and does NOT mean a better air purifier. The flow should match the size of the space being cleaned because higher flow, everything else being equal means one or more of the following: louder, larger, more energy, less filtration. Many of the markplace episodes mave these unsubstantiated ideas.
I can say you are wrong - for most people, the CADR is the most important. Without enough flow rate, you air are not get cleaned it should be.
It's still not a good air purifier
How come they didn't test the quality of the filter? I don't know much about air filters but if I were to purchase one, I'd like to know what they can filter along with the speed.
Same deal as car air filters
@Jessie O. Lee he stated it was a high efficiency filter, likely a 2200 filtration level, a bit lower than hepa rated.
Also at the beginning they stated "they all use HEPA filters"
@@Sir.Craze- yup i wanted to reply about this when i saw the video but got too lazy
Fan filter at 19:20
CADR should not be the measure. In some other videos, they measured the quantity of pollutants before and after and I think thats more appropriate way how effective an air purifier is in eliminating pollutants in air.
You can compare all of these units to each other. Purifiers with lower CADR/CFM can still be effective in smaller spaces. Comparing the Blueair 211 to the Levoit unit is comparing apples to oranges. The smaller Levoit unit would be perfectly fine in a small office space, bathroom etc where the large Blueair is good for bedrooms, living rooms, dens.
An yes humidifiers can put particles in the air, but if you use purified water or deiozinied water it helps.
For anything like this you need to ask more questions and present the whole picture.
I should go and build my own purifier! Thanks Marketplace, I learn more from you.
I like Dyson is not because of its purification ability, but its quietness. Try to sleep with that fan with tape on is impossible for a light sleeper.
During the smoke of the Okanagan fires we bought one of those Honeywell air purifiers with the heap filters. It sure cleaned up the smoke and our life better.
I have been using the fan with a 3M Filtrete furnace air filter for years. Unlike this video, make sure that you tape the correct side of the filter to the fan. The filters are unidirectional, and there are arrows on the perimeter of the filter showing the direction air needs to flow (metal reinforcement side inward). Other than that, thanks for doing all of the testing, and analysis, there are few sources of scientific information such as this report.
Thank you, all involved. It comes a good time. What’s the sustainability of air filtration like?
Homemade filter with $25 fan does work. When I first used it for 2 week on off about an hour a day and the filter turned black. I replaced the filter now it doesn't turn black anymore at least not as fast after a year later filter is still decent.
The heating in the winter completely dries out indoor air thus necessitating a humidifier. This professor is full of it
So so so glad i found this. I have been looking online at air purifiers the last few days and this really helped.
I really wish I saw this before buying a Levoit, in the process of returning it and building my own
1. Got an ad for an air purifier. I know 50% of the reaction is "well, duh" but even as someone who grew up with advertising like that... I still get a fealing of "Woah. Freeky!"
2. I'm about to buy an air purifier. That's remarkably good timing...
aside from looking at the CADR, any other features we need to
be looking for?
The home made one with the fan and filter is a great idea and works fantastic but, there is something to consider. Fans need to breathe in order to work correctly and the blades need to be kept clean and free from debris on the sharp edges in order to move the most air possible. The lifespan of the fan motor will be shortened from heat and strain of trying to move air through the filter. Listen to the fan when in operation for any abnormal noise from the motor because it will start to short out over time from the lubricant and the bearings drying out. Also feel the temperature of the power cord as it too will heat up from trying to consume more power to feed the motor over prolonged times of operation. If you sense anything odd, please stop using it and stay safe.
Interesting would love to know what a good solution is then for humidity in the air. Especially in winter when we have the heater on?
same, I need a humidifier for medical reasons and want to know what a good one would be.
I use distilled water and I have no problems at all. It’s just a hassle to go buy it every few days from the drug store. I highly recommend though.
look into “evaporative” air purifiers that do not release any visible steam
Evaporative humidifier is what you want, unless you have RO water or very soft tap water, don't bother with ultrasonic, it will send, not only the minerals in the water but everything else in the air (eg bacteria or mold that can grow in there)
Measure the humidity first.
I’m totally trying the filtered box fan. Happy to learn about the humidifiers as well.
Come on guys, Dyson actually sent a person and you guys cut up his responses to be more dramatic.
Thank you for your precious advices. I discovered your study after purchasing my Honeywell. And since we have a lot of smog this summer and I sadly had to move to an appartment close to trafic where a very big smoker used to live and it still smells awfull, I also built the one you showed us. I breath easier and feel much better.
I live in a small apartment and I had never though to check my air filter because I had never seen it (it is in the ceiling). Let's just say I will be buying a new one tomorrow.
