Air Oasis iAdapt 2.0 H13 HEPA Filter Purifier Reduces 99% of Viruses, Mold, Dust, Smoke, Pollen & Odors Quietest on The Market WiFi Compatible 2,650 Sq Ft of Clean

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.

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

I have 2 of these now for 3 months. The replaced my Oransi because it was about 8 years old and hard to find filters for. The one I had was recommended by a pulmonary specialist at the time. I was spoiled so I was concerned I needed good ones. This one had some new features that seemed like upgrades. They are so much quieter and very effective. I have 2 cats and you cannot smell the litter or wonky old cat pee haunts with these. Sunday morning bacon doesn’t disgust me anymore either. The filter life seems to be excellent. Breathing is important people. I have found myself much better in the morning with my lung issues. And the dust in the house is lessened. My furnace filter seems to be a lot happier too.

Of the five different brands I have tried, these guys are the best. From the quality of the build to the noticeable difference in air quality. Had some wet dogs and this eliminated the smell in a 500sf area in about 15 minutes.

It was suggested to my husband and myself that we get this unit because our ranch house is dusty, and it does have mold because we are close to the ocean. So far so good, it seems to be very effective
