Filter King AF16x20x1-M11 Merv 11 Air Filter 16x20x1

Product Description

The FILTER KING AF16x20x1-M11 is a MERV 11 pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 16x20x1 inches and an actual size of 15.5 x 19.5 x 0.75 inches, this filter fits standard 1-inch filter slots found in furnaces, air handlers, and return-air grilles. At MERV 11, it captures finer airborne particulates than basic fiberglass or lower-rated pleated media, making it a solid choice for systems where air quality and equipment protection both matter. Licensed HVAC technicians and experienced service pros typically specify MERV 11 when a household has moderate dust levels, pet dander, or occupants with mild respiratory sensitivities.

This filter is suited for forced-air heating and cooling systems in residential applications and smaller commercial settings that use standard 1-inch filter housings. The 16x20x1 nominal size is one of the most common filter slots in the field, appearing across a wide range of gas furnaces, heat pumps, and split-system air handlers. Each purchase includes a quantity of 10 filters, making it practical for stocking multiple units on a service route or maintaining a supply at a single property.

Installation Notes

Air filters of this type are installed by HVAC technicians or qualified service personnel. Always shut down the system at the thermostat and disconnect power at the breaker before opening the filter compartment. Install with the airflow arrow on the filter frame pointing toward the blower, away from the return-air side. Replace at intervals appropriate to system runtime and indoor air quality conditions, typically every 60 to 90 days in residential service.
