Filter King AF14x20x1-M11 Merv 11 Air Filter 14x20x1

Product Description

The FILTER KING AF14x20x1-M11 is a MERV 11 pleated HVAC air filter designed for residential and light commercial forced-air systems. With a nominal size of 14x20x1 and an actual size of 13.5 x 19.5 x 0.75 inches, it fits standard 1-inch filter slots found in furnaces, air handlers, and heat pump systems. MERV 11 filtration captures a broad range of airborne particulates including dust, pollen, mold spores, pet dander, and fine lint, making it a solid choice for households with allergy concerns or moderate air quality requirements. This filter is sold in a quantity of 10 per order.

This filter is appropriate for residential furnaces, central air conditioning systems, and air handlers using standard 1-inch filter housings. It suits applications where improved indoor air quality is a priority over the baseline MERV 8 ratings common in builder-grade filters. HVAC technicians and homeowners performing routine maintenance will find this filter a direct drop-in for systems calling for a 14x20x1 nominal filter. The MERV 11 rating balances filtration efficiency with airflow, making it compatible with most residential system static pressure requirements.

Installation Notes

Air filter replacement is a routine maintenance task performed by HVAC technicians and qualified homeowners. Always set the system thermostat to off before opening the filter compartment. Install the filter with the airflow arrow on the frame pointing toward the blower, away from the return air duct. Replace at regular intervals based on system use, occupancy, and indoor air quality conditions — MERV 11 filters typically require more frequent inspection than lower-rated filters in high-dust environments.
