80% of all HVAC systems will accept the 5″ MERV 10 filter which reduces "filter bypass" and increases air quality in your home. Gaps between the filter and filter frames ("filter bypass") allow particles to be pulled around the filter, entering the duct system and ultimately, your home or office. Particles that by-pass the filtering process, can accumulate on the evaporator coils. A 0.05-inch accumulation of these particles can reduce efficiency and increase utility bills up to 37%. These same particles provide nutrients for mold, mildew and other biological contaminants that can breed and grow in the ventilation system. Our 5" filter’s self sealing gasket conforms to imperfections in the filter track, eliminating filter by-pass, and preserving the integrity of the MERV 10 rating. Reduced resistance to airflow also allows your air-conditioning/heating system to operate more efficiently reducing energy consumption by as much as 300% compared to one-inch pleat filters. Your 5" filter only needs to be changed twice per year. For maximum efficiency, we recommend the Air One Value Protection Plan which includes changing your filter as well as inspecting your heating and cooling systems to ensure they are running at maximum efficiency.
