Flat air filters are the standard-sized air filters used in residential and commercial buildings, typically inserted into the flow of air as it passes through the HVAC system. These polyester air filters, fiberglass air filters and poly/glass air filters are changed at least monthly, unlike some some premium pleated air filters, which may be changed less often. Filters may vary by dimensions, media type, air flow (in FPM), filter efficiency and Minimum Efficiency Reporting Value (MERV - the higher the MERV, the finer the filtration). For higher indoor air quality, check out our ring link panel filters.
