Bestair Pro Furnace Air Cleaner Furnace Air Cleaner Filter, 20x25x5, MERV 13, High Capacity, Synthetic

These pleated air filters are sized to install into compatible air cleaner box on a furnace to remove contaminants from the air stream. They reduce indoor air pollution in commercial and residential spaces.

Pleated air filters capture airborne contaminants more effectively than non-pleated air filters because the pleated filter media provides more surface area for trapping contaminants than non-pleated media. These filters are commonly installed in HVAC systems in food and beverage, healthcare, hospitality, education, and industrial facilities to remove contaminants from the air stream and improve the quality of the air. They also prevent the contaminants from building up in the equipment and causing damage to it. The filters are designed to be discarded when they are spent. They typically have a MERV (minimum efficiency reporting value) rating of between 7 and 13. A filter's MERV rating measures how efficiently it removes contaminants from the air stream based on the size of the particles it can effectively capture. The higher the MERV rating is, the more effectively the filter traps small particles.
