Filter King AF16x20x4-M8 Pleated Air Filter Merv 8

Product Description

The FILTER KING AF16x20x4-M8 is a MERV 8 pleated air filter designed for whole-house HVAC air filtration systems. With a nominal size of 16x20x4 inches and an actual size of 15.5 x 19.5 x 3.75 inches, this filter fits standard residential return-air grilles and media cabinet filter housings sized for the 16x20x4 slot. At MERV 8, it captures a broad range of airborne particulates including dust, pollen, mold spores, and pet dander, making it a solid baseline filter for residential forced-air systems. HVAC technicians and service pros routinely stock this size for common residential applications.

This filter is intended for whole-house forced-air systems in residential settings, including gas furnaces, heat pumps, and central air conditioning systems that use a 16x20x4 media filter cabinet or return-air box. MERV 8 filtration is appropriate for homes requiring improved particulate control over standard fiberglass filters without the static pressure restriction associated with higher MERV ratings. It is sold in a quantity of 10 per order, making it practical for stocking multiple units for seasonal changeouts or multi-unit service routes.

Check and replace filters on a schedule appropriate to system runtime and indoor air quality conditions, typically every 3 to 6 months for MERV 8 filters in residential applications.
