- In this video we review Dyson air purifiers. This review applies to the Pure Cool Me (BP01), Pure Cool Desk (DP04), Pure Cool Tower (TP04) and Pure Hot + Cool (HP04).
It also, for the most part, applies to Cryptomic models - the HP06, TP06, etc. although Cryptomic models have improved gas filtration and add an air quality LCD display which is not covered in this review.
Current list of top rated air purifiers overall:
1. Winix 5500-2 - geni.us/yD1ZE (on Amazon)
2. Coway Mighty - geni.us/B1q9 (on Amazon)
3. Austin Air HealthMate - geni.us/RJMt4c (on Amazon)

I watched this video again recently and want to make two corrections:
1. In this video I use the term “airflow” very loosely. I say that Dysons have “high airflow”, meaning that they move a lot of filtered AND unfiltered air.
In all of my other videos I use the term “airflow” differently. I define airflow as the volume of air an air purifier can process - through its filters - per unit time (CFM). According to this definition, Dysons do not have high airflow because they only pull up to 100 CFM of air through their filters each minute.
It would have been better for me to simply say Dysons move a lot of air - i.e. they work well as fans - instead of saying they have “high airflow”.
2. In this video I incorrectly talk about the speed of the air multiplying when describing air multiplier technology.
Instead, I should have talked about the volume of air multiplying when describing this technology.
The movement of air through the groove inside the top hoop of the air purifier creates an area of low pressure which pulls air from behind the hoop, through the hoop. This multiplies the volume of (mostly unfiltered) air through the hoop. This is air multiplier technology. It has nothing to do with the speed of the air.
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!
man I love this channel.. pure unbiased reviews of things that I want to buy.
Thank you. The only review I’ve found so far that actually showed negatives and talked about the CFM and how it can be noisy.
I would recommend Vacum Wars's channel about comparing and testing IN acion performances too. czcams.com/video/CXL5NoX25XM/video.html
Almost any air purifier creates noise, this creates a lot of noise on max speed, but not more noise then large air purifiers and the noise is negligible compared to a box fan. Again you do not buy this product to clean air, it cleans the air and is a fan/heater.
@@Bound4Earth but fans and heaters are not $500 lol.
I’ve been binge watching them bc they’re so objective and factual, no bs :3
This is an awesome review. I almost purchased a Dyson air purifier but after watching your review. I am going to wait for a sale on one of your recommendations. You saved me from making an expensive purchase and know what to look for.
Very well summarised, thanks. What I took home is that if I want an air purifier, I'll get one made for air purification as its single purpose. At the end of the day, it seems the Dyson model is a fan prior to being a filtration appliance.
The channel has the perfect name and best of all it lives up to the name. The quality of the videos is not tied to the number of subscribers, I am very happy to be a new subscriber. I need this not only to make intelligent decisions but also to just learn about the best technologies out there, advertising can be fraudulently misleading, which makes this channel and channels like it absolutely necessary! I am lucky to be among the early subscribers as I see this channel passing 10 millions subscribers based on the professionalism and quality of the videos. At this point it's not about the money, so thanks a lot for investing this much on this new yet one of the best channels!
Thank you for the kind words and welcome!
Fantastic analytical review, you really helped me decide if it is right tool for my job. Subscribed!
I live in a smaller apartment and have 2 Dysons. They are great and I can tell a major difference with my asthma. Not to mention the warranty service is great.
If you get the $80 air purifiers, you would get the same result without spending 5x for Dyson branding.
dcentral true but can it serve as a fan as well? Furthermore the resell value is like half of what you bought it for so you are not paying full price.
dcentral I’m paying for fashion too, I want a cute house while my air is getting cleaned
John Huynh nice comment to a good response dcentral gave.
Antonio Johnson, it's the warranty for me! Worry-free....
Very good review. First time I've watched an entire one in a while. What unit would you recommend to clear a 500 square foot space in an warehouse office? Totally sheet rock enclosed.
Thank you for an Excellent and thorough video explanation this particular brand of air purifiers. It's good to know our world has great men, such as yourself, sharing in knowledge to assist consumers in making the best buying decisions for these type products. SALUTE!
Thank you for the kind words! I really do appreciate it!
Thanks for the referral link!
Besides the modern cool look, I think I'd prefer the GermGuardian 4825 unit, or even the winix 5500-2 or the Honeywell hpa200/300 instead of the dyson.
Those GermGuardian air purifiers are nice with the added UV-C light
Hi there, just to provide further insight. The air multiplier technology also creates a low air pressure pocket in the middle of the ring with the accelerated air and and wing inspired design. Whilst this doesn’t help improve the CFM processed it does help circulate the air, improving fan performance and helping it with larger rooms than many competing filters.
Thank you for your additional insight into how the air multiplier technology works. However, I do have to disagree with you on your point about greater air circulation resulting in better air purification performance. My testing showed that while this theory sounds reasonable (I thought the same as you about air circulation and air purification performance before testing), it doesn't pan out this way in the real world. Most particles are small enough so that they will easily move to areas of low concentration without requiring any physical movement of air. I tested the same air purifier multiple times in the same large room and no matter if I placed it in the center or edges of the room it would lower particle concentration at the same rate. I also tested multiple other air purifiers in the same room, each with a different exhaust air speed and different exhaust orientation. These tests showed no correlation between exhaust air speed or the direction of the exhaust air and the rate at which these units could lower particle concentration in the room. The only variable that mattered was CFM.
Got myself a winix after watching the video. Thanks for the in-depth review!
You're welcome!
Thank you for the thorough awesome work you're doing.
What about the larger Dyson units? Can they handle larger rooms? Thank you for giving us this much needed information. ❤️👍🏼 A great honest review, I love this so I subscribed. ❤️👌👍🏼😉
He said no, because of no higher CFM
Thank you! This was super helpful and I'm glad I watched before paying $$$$ for the Dyson.
Would love it if you do an updated review of Dyson purifier fans especially since they introduced a small "personal" purifier (pure cool me BP01). Curious to see how that performs.
I do plan on testing newer Dyson units in the future.
Thank you so much for this excellent information.
I'm looking into getting this air purifier specially when I do resin work, which one can you recommend?
Do u know about AirQuality KJ series of portable air purifiers? Can u do a review on it?
Hey I would love to see a review on the Medify Air MA40. There are a few reviews out there already, but I love your reviews since they’re more technically in depth, and actually put the manufacturer claims to the test. I’ve done some research my self, and was ready to purchase the Coway Air Mega 400, until I saw your review where you pretty much debunked their claimed 1,600 sq.ft. of coverage after doing some testing comparing other lower CFM units. After realizing this, I narrowed it down to the Medify Air MA40 @ 200CFM. I would love to see your take on this air purifier. Thanks!
Would you guys consider doing a analysis on their new line of purifiers with the Hepa filters?
I had no idea about the CFM although you probably mentioned it in your review of the Winix 5500-2. I think it was high.
How to you know what machine is filtering the best you dont masure ???
Thank you for your review.
I hope Dyson adds the following into their product.
1. Add the product serial number into the app.
2. When replacing filters. The new filters should come with a peel off sticker marked “new”. I’m sure people get confused when changing filters , especially the carbon filter. They both look new., at least mine.
3. Oscillation should have a manual setting as well...Are these suggestions already implemented ?
thanks a lot! the best review I have seen!
I wonder if this applies to the newer models they have now 🤔
what about the glass hepa filters? wouldn't small particles of the filter break off and go into the air? cause glass hepa filter is a fiberglass filter right? isnt fiberglass bad for you?
Please review Amway Atmosphere air purifiers. There is a lot of marketing happening around it. We need your critical examination on it. Thanks for the education in this subject.
Of course!
Only its round base is effective component of Air Purifier, which is small.
You did not mention anything about Dyson polar tests, which showed its aur purifier coverage to be effective for 600 Sq ft. They say CADR isn't the only reliable matrix for performance measurement.
I didn't know that Kevin Love is now reviewing Air Purifiers. Good Move.
That was funny...
That’s actually his cousin, Ricky Love.
No, actually that’s McLOVIN
I don't see it
Cant unseeeeee
I'm so impressed with your objective review about the Dyson that I can't thank you enough! I recently bought a Whirlpool whispur WP1000p air purifier and I'm giving it a 30-day run through but I already know after reviewing your website that I will be sending it back and it all probability getting the Winix 5500-2. Have you revert viewed the whirlpool WP 1000p air purifier and if so what do you think about it?
Thank you so very very much! Michael
I haven't had a chance to test the Whirlpool WP1000 though looking at its specifications, it looks like it has similar airflow and a HEPA filter just like the Winix. It doesn't appear to have a pellet based gas filter though.
All in all, I would expect the Whirlpool to offer similar particle filtration to the Winix but worse unwanted gas (VOCs/odor) filtration.
I have a winix and the first filter is a fine mesh screen filter to keep the large dust from making the carbon filter less effective and clogging the true hepa filter and carbon filter and it cost like 200 dollars and does 480 square ft and it blows the air straight up to the ceiling that it moves all the air effectively and has a 12 or 13 inch squirrel cage fan and a dc motor and its quite while moving all the air in the room while being next to it
Wish thy are for bigger rooms.
I got now AEG AX9-604 looks super in dark gray+wood legs. 600cfm. 130m2 and got very good app and us max onlye 41watt.
Any thoughts on the Filtrete Large Room Tower 290 sqft air purifier or filtrete air purifiers in general? It uses F1 filters. Seems pretty reasonably priced as well.
The Filtrete Large Room Tower you are referring to does have a reasonable output (approx. 200 CFM) for the price and I do like the fact that it uses inexpensive F1 filters, but the top rated Winix offers even better output (approx. 250 CFM) compared to its price and offers much better gas and pre-filtration.
Hi there. I was looking to get a Dyson pure cool desk but luckly I came across your channel. For dust and mold spores would you recommend Winix zero air purifier in about 150sq feet? Seen your other reviews about what's best for mold but in Ireland is very hard to get the Winix 5500-2...
Thanks a lot:)
Yes, in your case I would recommend the Winix Zero. It looks to have identical specifications and filters to that of the Winix 5300-2. The carbon filter quality is not as good as it is with the 5500-2 but otherwise performance should be identical to the 5500-2.
I'm very new in the world of air purifiers and I learned quite a lot from watching your videos because you make it easy to understand compared with other reviews out there that's why I subscribed straight away. Thanks a lot.
@@ionutd.6165 You're very welcome. Glad I could help!
Is it possible to buy the winix 5000 in Europe? The coway units looks like Philips
The Winix 5500-2 does not appear to be sold in Europe. The closest available option is the Winix Zero Pro.
thanks for the info. glad i found out it wasn't worth the price for me.
Great review.
My Dyson HP 04 is tested at 617 CFM (6 X more air volume)...a far cry from 100 CFM claimed on this channel. Interestingly enough, this channel is the only source making such dismal CFM claims...maybe evaluating such an old model may have something to do with it? Cheers!
All I gotta say just like with any electronic you get what you pay for. I just bought my Dyson Tp01 on sale at Best buy a couple weeks ago so I'm yet to change the filter obviously but I know Dyson stands by their name and I'm sure the air quality in my home will be better than before.
8:42 so studio apartments and small enclosed office work space are the best application for this air filter then?
Yes, in a sufficiently small space these units can be effective. Although I would still recommend using a particle meter to monitor its efficacy just to be sure.
Consumer Analysis - I hear this a lot but it seems to also be determined by your air quality goals and what issues you’re dealing with. In our case, our home is approximately 1500 sf, two story. Generally the widows are closed and HVAC is running. We placed one Dyson upstairs and one Dyson downstairs. We can watch the air quality vary over time. The single biggest negative impact seems to come from extended use of our Airfryer. Cooking sausage, which takes about 25 minutes if the Airfryer is fully loaded, can take the air quality number up to 999 (the highest number the Dyson unit will report, it’s probably higher) I was a little surprised to find the air quality number upstairs also spikes at about the same number, only slightly delayed and slightly lower number. Both units report back to “green” levels within an hour or so. During this time we don’t “notice” any degradation in air quality (Dyson registers “purple” like EVACUATE IMMEDIATELY!!! 😄 I’m sure a higher CFM unit would take less time but the Dysons will, eventually, get the job done. Unless your breathing sensitivities are such that you can’t tolerate occasional spikes that may take a bit to clear (or your environment is constantly creating significant air quality issues (like a commercial kitchen) I think limiting the application of a Dyson to 150sf room is very misleading. Yes, they are pricy but they work well (for our situation) and provide fan function we require without having multiple devices running all over the house. A plus, for us
It works great as a fan/heater near a desk for a personal computer or workspace. My room is 12 x 12 and it can heat the room to uncomfortably high levels if left on.
@@kbuzbee Purple doesn't mean abandon all hope and run away. I smoke myself and one cigarette can make it run from 20-40 up to 300. That isn't great for your lungs but far from EVACUATE IMMEDIATELY DEATH IMPENDING. I get that you implied this is the way Dyson portrays it, but they aren't wrong. If your air quality stayed in the severe 300 plus range overtime that would be bad. But even without an air filter even cigarette smoke dissipates, it just takes longer. I think their rating are more than adequate.
I also agree with you finding that this can filter a much larger room or space then most channels portray. To pretend that CFM alone equates to room size ignores circumstances. What is constantly going into the air that needs to be filtered 24/7 and if that is the case, perhaps you should consider a home air purifier as no stand alone solution would be adequate enough. Math involves context to put it into perspective and that is what most of these channels ignore. They just look at room filtered this many times an hour. Most people don't want a lout air filter running all the time and this is another benfit to Dyson as it can run in auto mode another ignored feature.
Dyson is not for everyone. I wouldn't even recommended the simple fan filter for most people, but if it has features you can or will use to include the expanded hot feature, it is beyond priceless and destroys cheap options. Especially the heating feature as the risk of fire is near non-existant because no dust particles can reach the heating element like all cheap space heaters and ignite.
Channels like this have their place. I just think they are overvalued as they look at numbers alone without context.
ONE THING that never gets mentioned is the sensor - of all the purifiers Dyson's sensor actually works like advertised.
Excellent review
Thank you!
Just got a brand new TP00 in my country, however a tiny part of the oval ring kinda peeled off on the back side and when I turn it on, I could feel some air coming out from that tiny opening, contacted Dyson here and they offered to have it exchanged with other new one, but it’s just too much hassle, I have to send the unboxing video of the product which fortunately I have, then go to the designated delivery service to have it sent back, then wait for period of time to get the new replacement smh.
Dyson has the new Cryptomic technology, I’d love to see if you can review that technology as well.
or an overview of cold catalysts in general
Would like to hear your thoughts on LIFA LA500V air purifier. Most of the purifiers I see online uses CADR, is it similar to CFM? Thanks!
The model you mentioned is specified to provide 600 m³/h of output which equates to about 350 CFM which is very good output. It also comes equipped with a HEPA filter. Overall, I would say it looks like a solid air purifier. For your question about CADR and CFM see this guide: www.consumeranalysis.com/guides/air-purifiers/cadr/
Thank you so much! That's awesome. 💕💕💕
The reason for the low volume of air is done on purpose. When purifiers go at super fast speeds, they tend to pull ultra fine particles past the filter. Dyson engineered the purifiers to prevent that and make sure everything that goes in stays in in one pass.
Where the info from? Hepa filter is a hepa filter. All work same.
@@Avdarmaly nope, not at all. indianexpress.com/article/technology/tech-news-technology/air-quality-dysons-polar-test-challenges-cadr-here-is-everything-you-need-to-know-5380937/
@@Avdarmaly There are HEPA filters that have much more efficiency and effectiveness, that's why there are air purifiers used in clean rooms in NASA, Intel, IBM, etc. The better they are at capturing ultra fine particles, the better the chances are at preventing severe asthma attacks, allergies, and in industrial settings, prevent damage to equipment. Dyson just found a more accurate form of CADR, their test is CADR, but turned up a notch. They also use CADR testing as their base line.
@@Avdarmaly Also, Dyson has had many third party tests from: AAFA, IBR labs, UL, etc, they have it all.
Given the 'air multiplier' effect - we assume that this would not be a good solution if someone is hoping for Covid HEPA filtering - as it would be pushing unfiltered air at the same time as the filtered air?
I’m no physicist. But wouldn’t all these units have to “push pull” air at the “same time” as you’ve mentioned? If not either an ever increasing vacuum or pressure chamber would be created in these units... not sure.
Also the air multiplier is just a simple trick of funneling air through a smaller space, increasing its speed but in turn reducing the surface area air is released through, it doesn’t necessarily change the amount of air or “time” you mentioned... but still what do I know
Yeah, I’m right. He explains this mid video when discussing CFM (cubic feet of air processed each minute). Lol basic physics.
Do you have a suggestion for an air purifier for a classroom--especially against viruses?
See my analysis here: www.consumeranalysis.com/guides/air-purifiers/air-purifier-for-germs/
How about new Dyson Pure humidify+cool? Is the filtration efficiency improved with the new model? Can you please make a review of it?
I do plan on buying it for review in the future.
YES, I'd love to see reviews of humidifiers. Also an explanation of steam vs cool mist humidifiers.
This is a great review! Actually convinced me to get the Dyson, too.
I live in a one BR apt in the City so it’s a small living space to be sure. Tech is important to me - I like having things connected and aesthetic is a bit important. Not too much but it’s nice to have a decent looking fan sitting in the room as opposed to the vornado.
My living room is larger than 150sq so it’ll take longer to clean it. Which is fine. I’ll just let it do it’s thing while i do mine. It’s expensive, yeah, but i can budget it in without trouble for now.
Where is the best placement for an air purifier ? I'd like to put it on top of a book case to save space.
My testing showed that it doesn't really matter where you place it in the room.
8:09 All air purifiers under the name of Pure Cool are tested in a room of 360 square feet, based on a 8-ft ceiling, according to Dyson official website. Are they lying and they are not suitable for a 360 square feet room? Where did you get that 100 CFM/150 sq. ft. number from?
Yes, I did test all units for output and corresponding square footage recommendations. Regarding manufacturer square footage specifications, see the beginning of this guide: www.consumeranalysis.com/guides/air-purifiers/best-air-purifier/
Everyone does a review about how good they are but no one did a test about the sensor how accurate it is! I had the fan for awhile! But last week Dyson fan been showing high particulate mater in my house for a straight week! Now I’m not sure if the fan is faulty or I got something in my house that pollutes my house!!!!
So does it plug into the wall or does it run on a battery?
It plugs into a wall.
The Amazon link for the winix isn't working for me, the reviews are great so would like to use your affiliate links if possible.
Thank you for letting me know. The link "works" but the 5500-2 has been out of stock on Amazon for several weeks now, which is why you're getting the page that you are. Hopefully, it will go back in stock soon. Otherwise, I'll have to change my links to point to another retailer.
Can you do the Xiaomi Mi Smart Air Purifier 3 ?
I will definitely look to review Xiaomi units in future videos.
Thanks for the review! I noticed for the TP04, the Dyson website says "Air Multiplier™ technology projects over 290 litres of purified air per second." which would be 614 cfm. This is at max setting of course. How did you come up with 100 cfm for your numbers? Thanks!
The 290 l/s number refers to the air it "pulls/pushes" through the top hoop (how much air its moving as a fan). 100 CFM refers to the air it processes through its filters (how much air it purifies).
@@consumer-analysis both numbers are volume per unit time. I am curious why these numbers would differ since the amount of air the system take in to purify is essentially the same amount of air it spits out of the hoop?
It could be that the inherent design of the Dyson "Air Multiplier" actually pulls more air through the "hoop" than it is pulling through the intake filter. Therefore, it "moves" much more air than it actually filters. Not a bad thing, just the way it works.
@@wombatsauce I see what you are trying to point, so the hoop kind of creates a venturi effect which also pulls normal air with the filtered air, eventually increasing the air volume it moves. This is actually an ingenious idea to implement in an air purifier.
The airflow over the ring creates low pressure thanks to Bernoulli effect. Since the low pressure is in a big circle, it creates a creates a tube of air with a big low pressure area. This pulls and accelerates the room air not from the fan/filter but from the room air behind the fan. This accounts for the difference.
CADR was first introduced in 1980s, which stands for Clean Air Delivery Rate. This test measures the clean air volume that a purifier can provide in fixed amount time, and it is a measurement of speed. It doesn’t measure filtration quality or focus on how well a purifier captures smaller particle sizes. In real homes, filtration quality matters. If particles aren’t captured the first time, they are released back into the room. An air purifier with a high CADR rating does not necessarily imply that it is doing a better job of purifying your room properly; it may in fact be throwing a lot of the pollutants back into the air in your home- when particles travel at high speed through the filter, it can bypass the filter and go back into the room. And also, it might not be projecting clean air around the whole room.
Dyson uses an updated version of testing called POLAR.
POLAR test lab is based on a larger room size of 27m2 (290 sq ft), with no added ceiling fan as we don’t use fans in peak pollution winter season in India. The air purifier is placed in corner of the room which replicates how it is used in real homes and pollution is pumped in the other corner. The test uses eight sensors in the corners of the room and one sensor in the centre, detecting particles of indoor air pollution that are 300 times narrower than a human hair. All machines are tested using their automatic pollution detection function as most consumers are not able to detect air pollution and just want to set their machine to automatically deal with any issues. The new testing method assesses the ability of machines to remove harmful particles and gases, the uniformity of the cleaning performance delivered around the whole room, and airflow projection. It starts when the machine thinks the room is polluted, and ends when the machine thinks it is clean. Analyzing the data across all nine sensors lets Dyson engineers ensure that our air purifiers are engineered for proper purification including efficient filtration and air projection, not simply for coverage time.
Also Dyson's filters are certified by the Asthma and Allergy Relief Foundation of America. No other competitors spend money on that testing because they will fail due to their cheaper filter material.
Hello brian,
I like dyson products, innovative & beautiful. CADR may not be comprehensive, but CADR is a very simple way of knowing how 'fast can the cleaning be done. A higher number means 'faster' cleaning.
Of course there are many other things to look at, in fact more important ones, such as efficiency of filter & smallest particle it can capture.
I did use dyson for a while. it did clean the air but took a little more time. In my room of 160 square feet, it took 45-50 minutes to bring the PM2.5 from 120-80
i think its CARD is 130 m3/hour
VINAY DUBEY what do you owN
I think the biggest argument for the Dyson Purifier is the heater function personally. Sure it won't heat up a big room, but it provides a lot of heat and does so safely as no dust can get past the filter. It also provides rotation to 350 degrees in newer models. Works great and can even heat a small office/computer room.
I was very tempted to buy the model that offered heat, but those models moved MUCH less air. Since I'd be using it as a fan 80% of the year, I didnt
@@FourJaysFour They move the same amount of air as a normal dyson fan. It is a multipurpose tool and as such works as well as any space heater I have used and great as a fan with a filter built in. It also offers rotations up to 350 degrees. Again it will never beat a simple air filter for $100, but again why would you be here if you wanted a simple air filter. Metrics matter and anything over $200 offers much more then just a simple filter.
@@FourJaysFour I understand that it moves less air when heating, but again all space heaters work this way. Edit: It moves a lot of air in fan mode so I don't quite understand the point you tried to make.
You can get a space heater for $20, either way you shouldn't be using electric heaters they way more expensive to run compared to natural gas.
@@Kyle-ut4jg If you are shopping for a space heater alone, you aren't buying Dyson. They aren't even comparable because the Pure filters any air that is heated. It nearly eliminates any risk of fire. It also filters the air. Again, any solo device can perform as well, but you buy a Dyson because it is a fan/air filtration/heating/good looking all in one. You pay more but that requires context that you remove. To be fair a $20 device wouldn't be recommended by anyone, you have to spend closer to $100 to get a device that anyone could say even does the same, but again with elevated fire risk that is not present here.
Can you review a Dyson pure cool cryptic air purifier?
In terms of particle (allergen, dust, etc.) filtration, Cryptomic models offer equal performance to older models. The only major change is better gas filtration - they are able to filter more unwanted gases than older models. All of that being said, I will definitely do a more detailed review in the future.
Formaldehyde is Everywhere (in very low levels)... even the human body produces it. I read that Formaldehyde disperses very quickly in the air. Unless there is very high concentration of Formaldehyde, there are no heath issues with being exposed to Formaldehyde. Save a few $$$ and get the HP04. You can put the difference towards a spare fiter... 🙂👍
Any chance of reviewing some of the popular Philips units?
I'm definitely strongly considering purchasing at least one Philips unit to test and review when I do another round-up of air purifiers.
@@consumer-analysis I'm considering Dyson DP04 or a Phillips for a small bedroom. Both are around the same price in the UK and since it's a small room I think the Dyson will cope. It also has the added bonus of the fan. I'm mainly looking for somethig that can run on a schedule and monitor air quality.
Why do you say the Dyson CFM is ROUND 100 max and from their website it claims 614 CFM for the model you are speaking of? "Dyson TP04 Pure Cool Link Purifying Tower Fan, 614 CFM, 120V ; Mounting Location Floor" Seems like a huge discrepancy?
Hi I have a question, I’m in the market for a air purifier and my budget is roughly under 1000$. At first, I was sold on IQAir, but unfortunately they’re not available in my country. I’m looking for a unit with a cfm of >250, a true HEPA filter, an active carbon filter, visually good looking, and that does not have any ionizing or “plasmawave” technology. After hours of research I landed on the tall Dyson Cool air purifier as it fit all my criteria (they claim it has a 868cfm), but now I have doubts and I’m unsure what to get. I would greatly appreciate any recommendations and wanted to say your videos are very educational! Not like any other reviews I’ve seen before. Thanks in advance :)
If you need CFM >250 I would recommend simply getting multiple 250 CFM units (i.e. multiple Winix 5500-2 or Coway Mighty units). The ionization can easily be turned off and left off with either unit. The truth is that you really don't need a $1,000 budget for a quality air purifier. You only need a larger budget if you want an air purifier optimized for gas filtration. If that's the case I would recommend the Austin HealthMate which costs about $500 to $600 and comes with 15 lb. of gas filtration media.
Thank you👍🏻
Phillip. I've got the blueair smoke stop. Its awesome. More reliable too. Highly recommended.
I recommend you invest your money and stop wasting it on dumb things.
@@Kyle-ut4jg actually I’m asthmatic and live in an area with high amounts of pollen in the air, so no lol. If I got money for a 1000$ air purifier, u rlly think I’m short on cash? Don’t assume that ur situation is everyone else’s. U actually sound like u should invest if this is much for u.
Please do a review on the newer units :)
I plan on doing so in the next few months. :)
I see the Winix you recommend is one that produces Ozone. What are your thoughts on Ozone? You must not be worried about it, if that's your top pick. It's just I hear so many different stories about Ozone, and it's starting to worry me. Thanks
Ozone production is only possible when the unit's ionizer is turned on and its ionizer can easily be turned off and left off. Note though that even with its ionizer turned on, the unit is completely safe to use: ww2.arb.ca.gov/our-work/programs/air-cleaners-ozone-products/california-certified-air-cleaning-devices
The ionizer is safe to use until your lungs gets infections, even small amounts of ozone can cause that
alas, the Germ Guardian isn't sold in Australian stores. I need one on my desk to filter VOCs in my immediate area due to everyone sanitising re COVID-19, which is is really irritating my asthmatic lungs. I like the fact that it supposed to be intelligent and adjust its filtration from monitoring the immediate environment. The one next to you in Australia is $648 and are on clearance. The only other one available is the heat/cooling at $899. Ouch.
Yes, they are quite expensive. You also don't really need the automatic mode as I explain here: czcams.com/video/Cgn-K5wbh2A/video.html
This device is certyfied against SARS-CoV-2, and have much effective performance www.safeair.ae
Im confused lol According to dysons website they can clean up to 450square feet. So what do I believe?
They certainly "can" clean higher square footage areas. The question is, to what extent? And the answer is - not very well due to low CFM.
@Albert J. Mendoza My testing indicates that the Home Depot number is fairly accurate. The actual CFM is right around that number.
Look at this czcams.com/video/8he8afjQyd8/video.html
@@consumer-analysis surely the time it takes to filter the air in an area is a consideration, which you don't mention in the video.
Anyone know of any non-Dyson air purifiers that double as a fan?
Molekule
@@FeldOtto55 Thank-you, too bad it costs even more than the Dysons though
Let’s say a dyson was at least 50% off it’s original price and is a 2 or 3 year old model. Would it be worth it then. Like a $400 dyson HPO1 on sale if $179? Worth it then?
Only if you really care for its aesthetics, fan functionality, and technology. Otherwise it still offers low CFM compared to top rated air purifiers by other brands at the same price (around $180).
My house smells like cat litter dust ( well... because of my cat’s litter). Do you think something like this will help if I put it in the same room as the litter box? I am desperate to get rid of the litter dust smell.
Yes, given sufficient time a Dyson air purifier will work. Top rated models will simply get the job done quicker.
Consumer Analysis Thank you so much!
@@KarinCohen_ Consider switching litters. We switched to a silicate cat litter through KittyPooClub and it is night and day difference. Won't go back.
Dom G we actually tried sooo many different cat litter, it’s insane. But I don’t think we tried that one, I’ll look it up. Thank you!
You description of the Air Multiplier technology is incorrect.
The small amount of filter air that is forced through the slit around the ring causes a low pressure area which sucks in more air from behind the unit through the hoop.
What this means is that the air coming from the device is not fully purified, some come from the filter and the majority comes from the back of the unit being sucked though by the air multiplier. Hence the low throughput.
On another note I have 3 of these device and 2 have had major faults which needed repairs.
I appreciate your insight here. I didn't consider the pressure differences you described in my analysis.
You can check this one www.safeair.ae
This is Industrial device. Much better than these toys
@@bartoszjankowski6234 Only $3,000 USD (for the greater than 170CFM unit) and as pretty as a 1980s Volvo 😂 . Love it.
👏🏾👏🏾👏🏾
@@ABG2412 Yes, But when it comes to air purification, it is a completely different shelf. The devices that are presented here do not even half of what safe air can filter. If you're looking for a home device, then probably a solution for a few hundred dollars is fine. However, if you need a device for industrial applications, it is definitely SAFE AIR.
Not much is also said about tightness of filters, and most of these designers blow up the reverberation, and instead of filtering. These devices here are very nice. That's a fact. But that's where their advantage ends.
I think the CFM may not be directly proportional to the cleaning capacity which may be missed. If you do not mix the air efficiently you can reprocess cleaned air. What Dyson does, in my opinion, is increase mixing and therefore perhaps avoid reprocessing the same cleaned air. I'm not an engineer but efficiency may not just be directly proportional to the amount of air drawn through if the same air is just reprocessed. That's just my logic for the design and the increased velocity and oscillation would be intresting to test the actual cleaning capacity of a fixed volume in a domestic setting with plenty of obstacles to flow.
Stop trying to defend your dumb purchase, you need to face the fact that you wasted your money.
What would you say about Xiaomi mi air purifier 2s?
The unit has low CFM (under 200 CFM) for its price. I would recommend a top rated unit like the Winix 5500-2 or Coway Mighty instead.
Before buying my Dyson, I watched this video (or one like it) and bought a cheaper air purifier. Here's how I came to regret that purchase, and ultimately bought a Dyson. I had a more traditional large purifier and switched to a Dyson. I noticed how over time, the Dyson seemed to make the whole room a *bit* cleaner. The previous unit I had just made half the room very clean. Yes, Dyson's specs are not technically as impressive, but the unit works better. It smartly moves air around, rather than just looping the same air back around the filter and killing the motor...
For example: My Dyson would pick up the smell of a steak from the other side of the room instantaneously, loudly blast the smell out of the apartment entirely within 5 minutes, and then continue filtering for another 30-45 minutes, providing sensor data on its display as it did so. The other filter (which was a good brand) picked up the smell after 5 minutes, worked hard for about 5 minutes, and then stopped. It only actually cleaned the smell from half the air in the apartment.
Technically the air purifier had better specs, but its motor crapped out after the 2 year warranty period, because I forgot to replace the filter, and it frankly overused the filter for the environment. The Dyson, by contrast, often keeps its fan off, but occasionally lances bad air from around the apartment using that jet effect, keeping things moving just enough to keep it just clean enough. It tells you when the filter needs replacing, which prevents undue stress on the motor. It collects dust better too. An absolute life-saver during the Australian bush fires, it did a great job of keeping the entire place free from smoke.
It doesn't keep things clinically clean for no purpose, it just does a nice job of creating a nice environment in a sustainable way. It also doubles as my clothes dryer (I just point it at the drying rack with the heat function on for 30 minutes), and a nice fan - it's been a much better, much greener, much longer lasting purchase than a dumb single use appliance that craps out when you lose interest in it.
Hmm, The volume of air sucked in the dyson is lower so less particules will reach the dyson unless the room is very tiny and the cfm of the dyson is more than enough, compared to non cooler purifier it will only push air further. So i m guessing that the dyson only made your room cleaner by pushing the dirt that disappeared from your room in the corners.
You could probably have the same or better effect by buying a $50 regular fan which will blow harder than the dyson and using it along the other purifier for a much lower cost than the dyson.
You’re not taking the air multiplier effect into account. It creates generalised airflow, dispersing the smell throughout the room, then cleans the air in the room over time using that airflow to mix it up.
@@alirobe the air multiplier effect just help push the weaker wind created by the dyson further away it doesn't help suck more particules. here is a comparison to just a cheap $15 fan, the dyson beats it in utility but lose in performance. czcams.com/video/dS0oFmzU06g/video.html
And there are much better fans out there than that cheap fan both in performance and utility for less than $100.
@@zifnab7691 air moves around in circles
So the Dyson units are basically just fans plus some air purification to boot. Theoretically, if the purifier is being ran all the time, couldn't it get an 800 Cubic Feet room purified eventually?
Or would the airflow coming in from other rooms just make it impossible?
Yes, in a completely sealed static room it could eventually process all of the air in the room. But in a real world application particles are constantly being introduced into the air - not just from other rooms but also from movement (e.g. walking across carpet or sitting on a sofa), appliances (e.g. cooking or even just bringing food into a room), etc. The net result is that you need to process all of the air in a room constantly at as high of a rate as possible to keep particle concentration as low as possible in the room.
Do the Dysons have pellet-based carbon or the regular fibrous sheet type carbon?
Fibrous - at least the older models. I'm not sure about the new Cryptomic units.
Consumer Analysis the HP/DP/TP04 series uses pellet style. Can’t attest to the HP/DP06 though
Just got my Dyson Humidify + Cool, i love this thing.
My biggest issue with the non Dyson devices is the optic. I wanted one for the Living Room, and the most of the other brands looked like s**t, like a refrigerator or something. I dont want one in my living room, lol.
Trusens z-2000 is nice! Suss it out
OFFdaHeazy suss it out?😄
Yeah the z2000 looks okay, but I don’t need it anymore, I am very happy with my Dyson.
@@Nookiezilla do you notice a difference in air quality?
Thanks dude
You're welcome!
Need to review the new gen ones. This is a old one, gen 2 I think
Nope. This is actually the 1st generation. The Dyson air purifier has improved drastically (night and day difference) since the 1st generation.
Dyson sent me an HP04 in a plain box, missing remote, no padding whatsoever. It was scratched up and the box was badly damaged. They said it would be 7-10 business days for a replacement because they're out of stock and 15-21 days for a refund. For $650.00 you would think they would care about their product enough to at least pack it with more than just 1 layer of thin cardboard for protection. Some air packs, anything. If they don't care about their products, why should I?
Needless to say, I opted for a replacement which turned into a refund because I simply couldn't wait that long. I bought 2 Winix air 5500-2s, one for me and one for my mom. It was still half the price of that one Dyson.
My experience with Dyson has just been an all around nightmare. Save yourself the hassle.
Sounds like a fake story
@@Bluefalcon888 -- 2nd that, or bought on eBay open box from a sketch source
I'm so late to this video it doesn't matter what I say but he is saying that this model represents all dyson fan/purifies basically but the tp04 did almost as good in some test and better in some in real world testing against the honeywell hpa300 which this person gave a 320 CFM rating and the dyson he give 100-150. If that was true how did it beat the honeywell in some of the test go watch vacuum wars review if you want to actually see the results. I would of been ok and never made a comment if this guy stuck to saying that these results only pertain to this model but no he grouped them all together without any testing of other models
The concern for me is that it’s neither a great purifier or a great fan. As a compromise device I’m thinking it’s better to get separate.
How do you qualify them as not great purifying?
@@j.ballsdeep420 there’s a measure, CADR, used to say how many times it can clean a room in one hour. If like me you are hoping to avoid spread of infections, Dyson does this less than good air purifiers that solely do that job, in my understanding.
Dyson uses the POLAR system. It's supposed to be way more accurate than cadr, but we have to trust them since they invented it. They don't care about how fast the purifier purified, they care about how well it purifies. Purifiers aren't supposed to get rid of smoke, that is what your HVAC system is for. Although Dyson purifiers can definitely get rid of smoke and everything else, the filtration focuses on ultra fine particles HVAC systems can't get, particles that cause premature death, asthma attacks, etc. Does that mean Dyson is better? Can't really say, one company that produces air purifiers in china to help people who can't afford expensive air purifiers and educate others on misleading claims, etc called smartair, had an article about dysons opinion on CADR. To summarize, Dyson had a couple of things wrong. So it's up for you to decide. I own a tp01, I truly enjoyed it. I'm gonna switch to a Honeywell insight, just for filter affordability and the auto feature. But I honestly can say it was a good product.
Why does mine say 800 sq ft?! HP04
I address manufacturer square footage claims near the beginning of this guide: www.consumeranalysis.com/guides/air-purifiers/best-air-purifier/
I think technically speaking, he’s right about the low CFM. But if you think carefully, Dyson air filter enables filtered air to be blown further away from
the unit, unlike dedicated air purifiers that only purifies the air around it. So the question is which air purifier is able to purify all parts of the room.every part of the room.
This is not DP04 , the one he shows in video is a old model than DP04 ,
Bro just tell me it Purifies the air
No but it has a great time display
I was searching for reviews for the Dyson Hot+cool purifier that I got just a couple of days ago. I was surprised that it wasn’t cleaning air fast enough and wouldn’t dip below “very poor” to “poor” Air Quality Index. You’ve explained it very well, sir. I may now end up returning this as for approx the equivalent of US $675 that I paid for it in India, I can get 5 Xiaomi Mi 3 purifiers and put them in almost every room of my house or more than one in one room. Clearly from a value standpoint, the Dyson just isn’t worth it. It’s CADR is too low and as a result the time taken is too high and the extent to which it can purify air is too low. Overall a bad purchase. Thank you for bringing the truth out. I can vouch for the validity of your claims as this is exactly what I’ve experienced.
Also, if anyone still wants to buy the Hot+Cool model, it does work well as a room heater. The air circulation is good for spreading warm air evenly all over the room. Think of it as a room heater first, and an air purifier second. From this point of view it can make sense. But again you can buy both of those separately and still save money. Remember with the Dyson we’re having to pay for the social media influencers and celebrities that are roped in to advertise for it. The price in this case doesn’t truly reflect the quality of the product. This once, you don’t actually get what you pay for.
Dyson are very good at marketing and aesthetics but always let down on performance. Remember talking to a PhD technician after testing a Dyson vac, failed all tests but she went and bought one anyway - asked her why, she said just couldn't resist the advertising !
I'm gonna file this under 'Never Happened'
when did this came out? dyson has beaten me to this idea. Xiaomi should make a similar one.
Not all Dyson products have the same design. You couldn't use their filters interchangably.
The Dyson air purifier that you show in your review is YEARS old. It is their 1st generation air purifier. Your review would have been far better if you had used the latest Dyson air purifier for 2020. The newest Dyson air purifiers have improved drastically since the 1st generation air purifier that you show.
The most prominent downsides of Dyson air purifiers - low airflow (CFM) and poor value - still apply to newer units.
A couple of things to point out:
This is Not an air purifier. The problem with every single review is that these dyson Fans are compared to air purifier only. It is a freaking fan and air purifier. Unfortunately there's nothing in the market to compare to.
My wife and son like to sleep with fans on in the room,they like both the noise and constant air and there are many people in the same situation,fir years we had ugly fans pointing at us blowing air at us, blowing clean air and also dust,hair, whatever is in the air. These dyson fans can do the same but they can filter the air that's blown towards us while keeping it self clean,not more taking apart dirty dusty parts and washing. Plus extremely safe around kids, can't tell you how stressful it is to have little kids in the house walking by a regular fan that's running and the first thing in your head is, please stay away, don't stick your fingers in there !!
If you are looking for air purifier only this is not fie you. If you want an elegant modern fan,that can clean the air that's blown towards you plus it is safe around kids since they don't have moving parts then my friend Dyson is your only choice. And is not a bad one. They are expensive but they last a very long time.
All these being said, they certainly can do better in price ,but why would they? Again they have no competition.
I had a fan in my room when I was 4 and it have moving parts and it was safe unlike the ones with the huge gaps in the grill and the air quality of the dyson is not 100% clean due to that regular air moves through it with the filtered air at the same time and time has not been there yet to tell if these things will last along time and a dyson fan is no where near vornado
They're not making so many now. New ones have less airflow.
Thanks for info and I do believe all dyson products are Over Hyped.
Go cry about it, they’re the apple of home appliances… no cap
