Great video!

Are air purifiers like having an Ac in your room? Do they give out cold air?

Great video, built one using all the techniques you shared…same filters and hot glue; however, while searching for the fan I found an AC infinity the same size and motor, but configured as an exhaust fan AC Infinity Airlift (AC-ALS12). It has an attached shroud that covers the filters with no fabrication. Thanks for the “how to” with the detailed instructions!

Is that a cat behind you looking for face time ? 🙃 ☮️💖🌻

I think we're being exposed to mold but everyone keeps saying everything looks fine. I found mold on about half the lumber in the attic but everyone says it can't affect our health. Even though I can smell it.

I am going to build one similar to yours, but I do have tools so I might use a piece of walnut for the top. I think a person could blow out the filter from the inside with compressed air like mechanics do to automotive air cleaners

Nah man. Build it yourself. It is ridiculously easy even if you go for "fancy" plywood box and PC fans and it is nice Sunday project :)

I'm more surprised that of the PC fans tested, CoolerMaster was the product of choice.

Thank you for making this video. It's also very brave of you to say out loud here that you have mold illness. Some countries would just throw people into mental institutes if they talk about mold illness. Keep it up~ 💪

Wow, Adrian Brody is not only a great actor but also makes really helpful instructional videos.

My allergy has become terrible the past month, i have always had slight allergy this time of year but never this extreme, so i had started to look at air purifiers. I also have a dust problem (maybe more of a too obsessedeith keeping everything dust free problem lol) and wanted one for quite sometime because of that. But i always just had the feeling that this industry had overpriced and unefficent products, though i never expected there to be any source that could help me navigate it or lead me to a better solution, so i mostly just abonded the idea. This video was exactly what i needed, what people like you do is very valuable and i appreciate your commitment and making this video

If you don’t want to measure, draw diagonal lines, instead. It would give you the same center.

Thank you for all the work and time you put into this video! I learned alot. Greetings from Germany

Thanks for all the videos on this stuff. You should do a video where you sum up all the stuff in your home and why it's there (ERV, old HRV, dehumidifier, fans, etc.), your thoughts on what you would have done different, and future projects to make it better. Doesn't need to be in great detail as you have all the other videos.

This is a beautiful video

I've been using single hose in my RV lately. My old and janky RV rooftop A/C's have recently started having issues working correctly under the sun and in the heat (back) and the other one broke down (front) & way to expensive to replace. So I found a way to inexpensively replace air conditioning inside here. But the single hose portables suck and underpowered (found this out the hard way) and why they don't work properly like a dual hose. I found out (the hard way) about what your explaining in this video. So I recently bought a dual hose (the Midea Duo) I hope it cools my inside down better than my weak single hose ones. Its twice as powerful than my single hose units combined. And I bought a heavy duty Window AC that I'm putting in my bedroom window (emergency pop out window of the RV). I'm needing to do a a simple hack modification but its being put in. I like your advice about the filters. thanks for sharing I think that way too along the lines of sucking in mold & dust that help with eliminating or reducing sucking it in both the dust & whatever else polluting inside both the unit and the room. Great video Thanks for sharing. I wish you success for your channel. I'll be watching your videos here on your channel.

I worked in a Hospital that had industrial size Air Purifies but could still smell odors especially around the restrooms, people have to have realistic expectations, you have to make a genuine effort to locate the sources of the bad odors and eliminate it. Don't expect any Air Purifier to do all the work for you

Most appropriate size air cleaners work very well, yeah a lot of them claim HEPA when they are not but they still remove most of the bad air and your much better with one than without

So which air purifier would you recommend for mold spores?

Is the Exhalaron adequate for filtering pollen?

Hey this is the first video I watch from your channel and I'm very impressed with all the information. I'm the founder or AirDeveloppa, we are a Thailand based air quality company that have developed an affordable yet effective air purifier similar to the ones you shared. Biggest difference is that we used a cylindrical filter and a single PC fan. I wanted to share some thoughts from my perspective as someone developing and selling products in this industry. I align with you in searching for the truth trough research and not falling victim of marketing non sense. However I must say that the current situation is a result of standard capitalism. For example, if I were to offer MERV filters and exclude carbon activated (my current filter is H11 with carbon activated), it will be considered inferior by the market. Even thought objectively and scientifically a MERV filter with hight CADR is better. It is sad but it is the truth. People buying in Amazon will compare 99.97% vs 90% fine particles filtration efficiency and immediately choose the one with the highest number. Another thing to consider. Adding more air purifiers doesn't always fix the problem and it can even make it worse if your house is not well insulated and there is polluted air outside. By having a lot of air purifiers you create a lot of negative pressure and as soon as a door is opened, a big chunk of air from outside will be dragged in to equalise the pressure. The best solution for this is a possitive pressure system where you filter the air outside and bring it in. This is better also in terms of CO2 concentration. Of course this system is more expensive and requires opening a hole in a wall. Thanks again for your video, it has been very informative and useful to me

Incredile research and evidence presented! Amazing video!

1:39

Oh wow, this is interesting. *goes to look at cleanairkit prices* Welp, HEPA filters it is...

The research put into this kept me hooked and interested, you've convinced me too!

I really enjoy and learn alot from your videos. Have you experimented with Algae air purifiers which scrub out the co2 and other particulates?

I love the design. Only thing it’s missing is a uvc light. It should be too hard to add one to the bottom.

I wished I had found this channel sooner, but better late than never. Great information and going to check out the Clean Air Kits.Thank you. Have a great day! Maybe now I will feel better. :-)

I think the fallacy here is you're comparing the airflow between the two filters for the same size. To get the same amount of airflow as the MERV13 filter, I would need a larger HEPA filter. If we get big enough HEPA filter which gives us as much air flow as that of the (smaller) MERV13 filter, won't we get the best of both worlds?

Does it help to insulate the vent going out to keep more heat out of the room?

I love to agitate carpet with an old worvick

Did u see the video of scientist comparing/having a co2 sensor vs voc sensor in classrooms, and sistem with vocs did better controling the fan speed than with co2

Whoa, I had to put down my cigarette for a moment when I saw this.

Can I just use a dual hose portable ac that uses fresh air? A good one with a variable speed inverter costs around $400.

What you need is something like an Airthings sensor. To quantifiably measure the particulate matter in the air. I know that my HEPA filter sometimes reduces the PM 2.5 to below measurable levels.

CADR is like with cars where faster cars may have lower MPGs but if what you want is fast acceleration then you'll want the car with more horsepower even if it's less efficient per mile. Why would you buy a really efficient car if it's slow and what you're going for is fast acceleration?

Have you done any research on Triad Aer Systems?

First, I want to start with the good, I love how you attacked the issue.. Clean air is a huge talking point in the wood working world but no other space I've ever occupied. Matt Risenger another youtuber does talk about it with construction from a building science perspective, I would check out his content, there are tons of things off gassing in our houses killing us slowly. I am currently in the process of remodeling my kitchen to get rid of my gas appliances. So back on track, the research was great, you're spreading wisdom and awareness, in service to your fellow consumer/humans. I dig it. A lot. Thank you. My nitpicks... I feel like you're a little harsh, sure some of these companies lie and mislead. But most people don't give a flying F about this topic. Even once aware. Most manufacturing is not a massive lab doing hard science leading to high quality products. Things would be a lot more expensive in general (and that sucks) all life is a balance between making things better, and giving people what they want. Car guys cry about how poorly cars are made. I point out all the time that these companies have INSANE ability to produce engineering marvels. The problem is not the car companies them selves. Its what people are willing to buy. Most people are not willing to buy something for 10X the cost, and even at the prices these companies are hiring people at, its till hard to find qualified staff. No one wants to work for free. So do companies slap lip stick on a pig to get us to part with our money? Yes, you're not wrong. I think the problem is not the companies its the consumer. This research has been going on a while, this problem didn't pop up today, people just don't place value in the correct places. Most people are excited to get a new set of Nike's or a new Purse they don't need. I would take the anger you have and redirect it towards your fellow man. Because one thing I could bet you a million dollars on. If all the sudden in door air quality became important to most Americans, with in 24 hours we would see a dozen manufactures making beautiful, low cost (relatively speaking) well functioning air purifiers that beat the breaks off what we have now. We just need more awareness.

At least where I live, the air purifiers list the CADR and the recommended maximum room size for these purifiers. I thought this should be mandatory everywhere.

I've kinda already invested 2 years ago in a Blueair blue pure 211, 2 Blueair Health Protect 7770is and an Alen breathesmart 75i which altogether was literally an arm and a leg, are you saying it was all for nothing?

Great video! Just saved me sooooo much money!

Ordered the clean air kit. Have been concerned about my hepa for a long time, and replacement filters are up to 60 dollars every time. I thank you for the cadr info, it resonated immediately.

So make a DIY air box

I don't trust a man who doesn't own powertools

Interesting that they dont have stuff like the IQ Air Health Pro Plus on any of these charts. Systems like that have high surface area and powerful motors. Granted they are expensive systems but those are HEPA air filters that work.

The majority of those HEPA filters on places like Amazon just are not well designed for filtering. Especially those like Levoit (and many many others) that have that design, have flow by (air that goes through the motor but doesnt actually get filtered), and are really just designed to be maketable.

Glutathione IV's in high doses will bee your best friend in detoxification of mold. Took my two years to start feeling my best and its a job everyday to stay healthy. Good Luck🙏🏼

Thank you Dude fellow chemical sensitive mold warrior here. Have had so many air cleaners in my life and I am going to give these a try as well. I hope this is accurate info, I like all the sources you provide. Hopefully you will get a discount if wee give them your name. Thanks and good luck with the mold healing 🙏🏼

Enjoyed all the info in your video and appreciated that it wasn't another stupid A.I. voice-over video... lol thanks again

so if its air volume ? Why not use a HEPA in the CR box , wouldnt that be the best of both worlds
