Includes 12 Carbon Filter Pads - Enough for approximately 1 year
Activated Carbon Filter Pads - 12 Activated Carbon Filters pads are supplied with each MARK-25 Smoke Eater. The activated carbon filter is changed every month and removes odors by absorbing the odor molecules into the filter. Since the activated carbon can only absorb a certain amount of molecules, it will begin releasing the trapped molecules, once it is full, back into the air if not properly maintained.
Carbon filters cannot be washed and must be changed every month.
