Air Oasis iAdapt H13 HEPA Filter Air Purifier | Reduces 99% of Viruses, Mold, Dust, Smoke, Pollen & Odors | Whisper Quiet Operation for Medium Size Rooms | 550 Sq Ft of Clean Air

This is not the cheapest but for what it does is the best value for the price. It really works well during my home renovation, killing mold we are ripping out of a leaky wall so no small with this running. Its size is bigger than expected but the noise level is almost zero. You can't even hear the fans running, it's just a very nice soft quiet swoosh of air. The dust and mold and VOC's smell etc are gone within an hour on lowest setting (which I strongly prefer to minimize noise and not blow the dust and stuff around the room). The only drawback is it uses wifi 5, aka IEEE 802.11n, with the ancient security protocols that have all been cracked. My router refused to allow this into my wifi because it does not have any modern wifi encryption standards. So, I had to set it up as a special "Internet of Things" on separate private VLAN with very lax wifi security. I wish they would offer an upgraded wifi 6 chip so people can't get into my home internet. After all that work, the app is fairly lame too. HOWEVER, it's very powerful on what it does it's like a cheap "air scrubber" for the mold that I was so worried about, I can't smell anything with this running while we work on the renovation.

This air purifier is quiet, works well, and gives me peace of mind that mold and mycotoxins are being removed from the air in my home!

The air purifier has worked great since we’ve gotten it. We’ve had a lot of smoke in the area from fires, and it has helped a lot.

Improved air quality was great and easy to use with simple instructions and easy assembly

This was the best rated HEPA air filter that I could find at a reasonable price range. The added UV light treatment to kill any harmful particles is an excellent feature. Using for cleaning a room that was formerly remediated for mold just to be absolutely sure the air is clean again.
