The pre-filter is important because not only does it remove the larger particles, it also helps prolong the life of the High Efficiency filter in the system. Essentially, the pre-filter is the first line of defense in maintaining your system; therefore promoting better indoor air quality. Pre-filters cannot be washed and must be changed monthly. Activated Carbon Filter Pads - 6 Activated Carbon Filters pads are supplied with each system. The activated carbon filter is changed every two months 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. The Carbon Filters cannot be washed and should be changed every 2 months. High Efficiency Filter - 1 - 12-inch High Efficiency Filter is supplied with each MARK-20 Commercial Air Purifier Smoke Eater and should be changed once per year.
