25dB on low speed, which sounds like whispering from 5 feet away.  52dB on the high fan setting, which sounds like a quiet conversation, a quiet office, or a quiet refrigerator.

Yes, Air Oasis air purifiers use ionization which has been third-party lab tested to reduce viruses and bacteria by up to 99%. It is of course important to continue cleaning surfaces as one normally would; however, ionization supports the mitigation of these concerns between cleanings and during occupancy.

HEPA and carbon filters reduce airborne particles and odors. However, HEPA filters cannot filter all of the smaller particles such as a virus particle. And much of them are on surfaces rather than in the air. This is where Air Oasis ionization makes a different and sets us apart from filter-only products commonly found on the market. For example, our ionization technologies reduce both the H1N1 strain of the flu (influenza) virus and Middle East Respiratory Syndrome Coronavirus (MERS-CoV) by more than 99% in a third-party party lab test. 

We tested bi-polar ionization against E. coli. After 60 minutes in a test chamber, over 99% of E. Coli was eliminated.

The iAdaptAir purifier employs both True HEPA and carbon filtration to address the particulate matter in smoke as well as the harmful VOCs and annoying odors that comes with smoke. Our True HEPA filter addresses particulate matter in sizes of .1 microns and smaller. The carbon filter absorbs harmful VOCs, reducing them in your indoor air.

The best answer is to avoid ‘undersizing’ a room with too small of a purifier. For classrooms we recommend a Medium or Large size. The benefit of a larger purifier is the larger filter can work to cycle and clean the air at a lower (quieter) fan speed.

We recommend operating the air purifiers throughout the school day. It’s also possible to schedule the purifier to turn on an hour before class starts and let it run through day. The scheduler function and app support various run cycles and durations.
