The Airpura V600 air purifier not only does an excellent job at removing irritating particles like pet dander, but it excels with its ability to absorb and neutralize strong chemicals, gases, and odors, particularly formaldehyde and ammonia. The Airpura V600 is our favorite 'pet air purifier' for a large room or homes with multiple pets providing superior dander and odor control. It is also one of our top picks for rendering chemical and VOC off-gassing issues from new home furnishings, renovations, office equipment or Chinese dry wall.
