iAdaptAir for Small Room

Purchased an iAdaptAir unit for a chronic Lyme patient (son) who is extremely sensitive to airborne pollutants such as voc's, mold spores, etc. We have been using a brand name hepa air purifier for years, but it wasn't able to adequately clean and sanitize the room air. After only one day of running the iAdaptAir, there was a noticeable improvement in air quality. Our son indicated that he is sleeping better since running the iAdaptAir. We highly recommend this product.

The Best Air Purifier I've Ever Owned

Great customer service. The unit arrived quickly and the product really works! I've tried ionic air purifiers, HEPA air purifiers... Nothing stacks up to the iAdaptAir. It's like they took the best HEPA, the best ionic air purifier...and put them all in one unit.

Frequently Asked Questions About HEPA Filtration

HEPA air purifiers are very effective at removing particulates of a certain size from the air. Using a filtration process, HEPA filters literally trap the particles and remove them from air circulation. Filter-equipped air purifiers, especially ones adding ionization, are a top choice for those wanting to quickly clear their indoor air of airborne particles like allergens, dust and pet dander.

HEPA air purifiers are not all designed in the same way. Some have lower-quality materials or are not rated highly enough regarding the size of the particles trapped. The ASMA U.S. DOE standard for HEPA filtration is that it removes 99.97% of particles from the air. If you want a HEPA air purifier, ensure it also has effective ionization.

HEPA is exceptionally proficient at removing allergens from the air. Particulates that often cause allergic reactions or allergy symptoms include pollen, pet dander, organic materials and dust. All of these can be physically removed from the air as they cycle through (and are trapped by) a HEPA filter.

HEPA filtration may reduce visible smoke in the air but has a limited ability to deal with the smell of wildfire, cigar or cigarette smoke. Air Oasis filters found in the iAdaptAir purifier use both HEPA and carbon filtration. Carbon filtration is a better match for reducing smoke odors and VOCs.
