Replacement Activated Carbon Filter Pads for PAC-22 Flush Mount Air Cleaner
The carbon filter in your PAC-22 adsorbs odors & gases. Because it can only adsorb a certain amount of odor & gas molecules, it's very important to maintain the charcoal filter. Basically, the carbon filter stops working once it's full with odor molecules.
6 activated charcoal filters included. Change your carbon filter in the PAC-22 a minimum of every 2 months.
