Filter King AF12x12x1-M11 Merv 11 Air Filter 12x12x1

Product Description

The FILTER KING AF12x12x1-M11 is a MERV 11 rated pleated air filter designed for residential and light commercial HVAC systems. With a nominal size of 12x12x1 inches and an actual size of 11.5 x 11.5 x 0.75 inches, this filter fits standard one-inch filter slots across a wide range of forced-air systems. MERV 11 filtration captures finer particulates than basic fiberglass or lower-rated filters, making it suitable for households with pets, mild allergy concerns, or elevated indoor air quality requirements. Installation requires no tools and is handled directly by the homeowner or the HVAC technician servicing the system.

This filter is appropriate for use in residential furnaces, air handlers, and central air conditioning systems that accept a standard 12x12x1 inch filter. The MERV 11 efficiency level balances airflow with particle capture, targeting dust, pollen, mold spores, pet dander, and some fine dust particles. It is well-suited for single-family homes and light commercial spaces where improved filtration is needed without significantly restricting system airflow.

Installation Notes

Power down the HVAC system at the thermostat before replacing the filter. Note the airflow direction arrow printed on the filter frame and orient it so the arrow points toward the blower or air handler. Slide the filter fully into the track to ensure a complete seal with no bypass gaps around the edges. Filter replacement intervals vary by system usage and indoor air quality conditions; consult the equipment manufacturer guidelines for recommended change frequency.
