Includes 6 Carbon Filter Pads - Enough for approximately 1 year
The activated carbon filter removes odors by absorbing the odor molecules into the filter. Activated carbon can only absorb a certain amount of molecules before it stops working. The easy-to-change carbon filters should be replaced, on average, every 2 months or as needed. Carbon filters CANNOT be washed.
Replace the MARK-15 carbon filter every 2 months.
