Filter King AF19.88x21.5x1A-M8 Merv 8 Air Filter

Product Description

The FILTER KING AF19.88x21.5x1A-M8 is a MERV 8 rated pleated air filter designed for residential and light commercial HVAC systems. It captures airborne particulates including dust, pollen, mold spores, and lint, helping maintain indoor air quality and protecting system components from debris buildup. With a nominal size of 19.88 x 21.5 x 1 inch and an actual size of 19.88 x 21.5 x 0.75 inches, this filter fits standard 1-inch filter slots. MERV 8 performance makes it a solid choice for most forced-air applications where balanced filtration and airflow are both priorities.

This filter is suited for use in residential forced-air furnaces, air handlers, and central air conditioning systems that accept a 1-inch pleated filter. It is typically installed by HVAC technicians during routine maintenance or filter change intervals, and is also accessible to knowledgeable homeowners performing self-service maintenance. The MERV 8 rating positions it above basic fiberglass filters while maintaining adequate static pressure for most residential blower configurations.

Installation Notes

HVAC technicians and qualified service personnel should power down the air handler or furnace at the disconnect or thermostat before replacing the filter.

Inspect the filter housing for gaps or bent tracks that could allow air bypass around the filter media. Filter replacement intervals vary by system load and environment but should be checked at regular service intervals.
