This is the air purifier that naturally cleans and deodorize the air using reindeer moss, coconut, wood carbon, and nano fibers. Unlike standard air purifiers, this uses biodegradable filters made of natural coconut fibers that capture dust, pollen, mold, pet dander, and bacteria as small as 0.3 microns. The unit is small enough to fit on a table or nightstand and also catches odors and volatile organic compounds (VOCs) including formaldehyde and other toxins emitted from paint, carpets, and adhesives. It filters and circulates a 387' square room in an hour while only producing under 70dB of sound. Includes a set of replaceable filters that lasts up to 12 months. USB plug. 81/2" H x 61/4" Diameter.
