HEPA Filters & MERV Ratings

The iAdaptAir® contains True HEPA filters. (The filter cartridge also includes a layer of Activated Carbon to help filter out VOCs.) Filter efficiency is often compared with the MERV rating scale. HEPA air filters exceed the ASHRAE test protocol 52.2 used in determining the MERV ratings. Air Oasis iAdaptAir HEPA filters are tested and certified to have at least 99.97% efficiency in removing particles as small as 0.1 microns.
