Replacement Activated Carbon Filter Pads for PR5.0 Flush Mount Air Cleaner
Replace the activated carbon filter every two months. The carbon filter adsorbs odor & gas molecules. 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 PR5.0 every 2 months.
