The Second Stage of Filtration in Airpura Air Purifiers
Carbon Filter - A whopping 18 pounds of carbon is typically found only in commercial grade air cleaners. With the Airpura carbon module, you can expect an odor-free, VOC-free and chemical-free environment. Carbon is a magnet for organic-based pollutants. The 2" carbon ring contains enough carbon to adsorb gases, chemicals, noxious odors and VOC's for up to 2 years!
It may be of interest to know that this same type of carbon is used in military gas masks to protect soldiers from airborne contamination.
This Carbon filter module can be used in the following Airpura air purifier models;
R600, R614, UV600, P600, P600+
