This Carrier compatible replacement filter fits Mechanical Air Cleaner 1400 and CMF2020.It has a MERV 13 filter efficiency value, which indicates how minute the particles that can be trapped by it. The higher the rating, the finer the filtration and the fewer the particles that pass through it. To further increase filtration, it has a pleated rather than a flat surface, thereby increasing the filtering surface area. This efficiently traps airborne minuscule particles such as dust, pollen, dust mites, lead, animal dander, smog, insecticide dust, mold spores, smoke and even bacteria and microscopic allergen as small as 0.3 microns. An additional benefit is that an air filter will also extend the life of your heating and cooling system by making it work more efficiently by preventing the accumulation of particles that settle on the evaporator and condenser coils.
