Changing the filters in your FM-2000 Commercial Flush Mount Air Filter and Smoke Eater on a regular basis is required to maintain the health of the unit. Pre-Filters (12) - The pre-filter is changed monthly and removes larger particles such as lint, hair, dust, and pollen. 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. For maximum results, pre-filters cannot be washed and must be changed on average every month. Activated Carbon Filter Pads (6) - 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. For maximum results, the Carbon Filters cannot be washed and should be changed on average every 2 months. High Efficiency Filter (1) - The High Efficiency filter removes the very small particles, such as smoke (tobacco, burning wood, oil, rosin), dust mites, spores, mold spores, pollen, spray paint, spray paint dust, ashes, cement dust, auto emissions, textile fibers, fiberglass, hairspray, insecticide dust, copier toner, and most viruses just to name a few. As you can see, the High Efficiency filter is an extremely important filter and when used and maintained properly will dramatically improve your indoor air quality. We cannot stress enough the importance of the High Efficiency filter to our system and the fact the High Efficiency filter must be maintained in order to achieve the maximum results. For maximum results, the High Efficiency filter cannot be washed and should be changed on average every year. NOTE - Recommended filter changes shown are on-average and may not represent every application. Some situations may require filter changes more often than others.
