CleanAirKits - Clean Air Kits

CleanAirKits is the quietest. Dyson second quietest. My Medify MA-112 is pretty quiet too.

CleanAirKits. None of these or any air purifier can deliver 200 CFM CADR at a reasonable sound level. A computer fan powered air purifiers like one from CAKs can deliver over 300 CFM and be completely quiet and use less than 10 watts. I've had all the expensive air purifiers and they all disappoint. IQ Air, Austin Air, Intellipure, Winix, Air Oasis, etc. Austin Air is my favorite out of those but even that one at a reasonable sound level on medium is only like 100 CFM. It is shown by many testers that a higher CFM air purifier always out performs the others. No matter the MERV or HEPA rating.

As others have mentioned, build yourself a Corsi-Rosenthal cube or get a cleanairkit that uses MERV 13 filters. I'm severely allergic to dust and dust mites and I have been astounded at the amount of dust my cube picks up. We even bought a 3d printed frame for ours off of Etsy so it looks a bit nicer than a bunch of air filters with tape. I've had one running in my home continually for 2 years. Equally if not more important: get rid of every shred of carpeting and decorative rugs in your home. I have a small rug under my desk chair to protect my hardwood floor and that is all.

They work very well. When covid hit i looked for a way to try and address aerosol transmission as someone who has never caught a light cold or had a touch of the flu in my life. If i get sick i get very sick. I put together 2 of these and bought a CO2 and a particulate air monitor and i was amazed at how dirty those filters would get in just a matter of months. After a while i bought filters that use PC fans because they are much, much quieter. I was lazy and bought them but if you are a little bit handy you can put them together yourself.
