As someone who is allergic to dust particles, I appreciate your work and the updated tests every year.

You are, without a doubt, my air purifier hero. I can not fathom the amount of wisdom that has been dropped in your air purifier series. You have single handedly made me the most knowledgeable about air purifiers out of anyone i know. You've done me a great service. You deserve a sub

[gonedays]

Bought the Medify from your previous video review. Couldn’t be happier. My air is so much cleaner in my house (2800 sq ft). I used to wear breathe right strips at night to help breathing through nose. I haven’t need to wear once since I bought the Medify.

By far the best and most concise video Ive seen regarding air purifiers. I’ve spent 3 full days reading analysis on air purifiers. This summed it all up. My head was spinning with info until your video! Thanks

[jigarpatel]

Great testing. Wish there was a specific VOC test so can tell how good at removing odors like cat smells

Currently have a Healthway Deluxe Air Purifier but haven’t been able to get filters for it in months. We got it because it’s supposed to be “hospital grade“ but in need of an air purifier to take its place while we wait on filters. What do you recommend for an air purifier that removes pollen, pet dander, etc but capable of large areas? Not concerned about price if it works well. Thanks for the video and thanks in advance for your insight.

I too have sinus issues and appreciate you giving it straight to us and in plain language with tests to prove it.

Test methodology: I’d suggest making air quality measurements from multiple points in room. Suggest ceiling, floor and near intake of air conditioner or heating units, as well as near curtains. Of course air quality measurements next to filter will get the best results.
Also compare it to what I would consider a baseline unit, which would be a box fan with Winix hepa and charcoal filters attached to the inlet.

How do these same filters continue to perform after extended use. I know some filters after awhile such as 8 weeks. Will start leeching particals out or the seal fails from what ive read. So basically im looking for long term testing.

Late to the game, but nicest (best) video testing of these air purifiers I've seen! Nice work!

[yilei]

Wow I am blown away by this test and the detailed list!! Thank you for your work!!

[Dragracer]

I bought the ma 112 because of your test, i thought I will take no auto mode for granted as long as it does its job. But happily surprised my 112 version got auto mode and also a light indicator with pollution level. It even has a pmi 2.5 value display.

Really appreciate these in depth videos. Can be difficult to find up to date videos similar to this.

[docwhoth]

Just wondering for a home with multiple rooms, is it better to have 1 large unit or smaller multiple units to clean the air properly? Can the large units exchange the air in the individual far away rooms, for instance a 3 or 4 bedroom home?

[lorawaloski]

This video singlehandedly saved me so much time I have to give you YT algorithm love with some engagement here as a comment. Props for a well done, well filmed, well edited review video. Btw, do you have affiliate links to those air quality meters you were using? I'd like to test my home to help determine which of these might really impact things the best, and which rooms actually need help!

[Falcon]

Great video. My house is against the freeway wall. My thermostat says poor IAQ. Once I open the windows and get fresh air in the IAQ starts to improve. I want to monitor this closely, would you recommend the Temtop LKC-1000S+ 2nd Gen?

[Mandy-gzxl]

Thank you for all your hard work! It is definitely appreciated! I especially appreciated that you let us see all the data in charts at the end! :)
Which in home air sensor (similar to your’s) is the best value and most accurate—that you recommend? And where can we buy it?

I battle serious health issues, so that would be invaluable to me! Do they test for mycotoxins?

Thanks again!! 😊💕

[sarachallahan]

Hi! New fan!! I have a question. I’m interested in the medify or the iqAir, it looks like medify is at the top of your list? Does it have a large 12 lb carbon filter like iqAir, and why isn’t iqair at the top of the list then? Also, I see that medify112 has a standard version and then an upgrade able version with UV light… what does the UV light do that the filters can’t already do? I have a big budget and price isn’t an issue, so I want to get the very best I can possibly get!! Thank you for answering both my questions!!! :) ❤
