Filter King AF24x24x4N-M11 Pleated Air Filter Merv 11

Product Description

The FILTER KING AF24x24x4N-M11 is a MERV 11 pleated HVAC air filter designed for forced-air heating and cooling systems. With a nominal size of 24x24x4 inches and an actual size of 23.38 x 23.38 x 3.75 inches, this 4-inch depth filter fits deep-filter housings and media cabinets. MERV 11 filtration captures finer particulates than standard MERV 8 filters, including fine dust, pollen, mold spores, pet dander, and some smoke particles, making it a solid choice for systems where improved indoor air quality is a priority without significantly restricting airflow.

This filter is suited for residential and light commercial forced-air systems that use a 24x24x4 inch filter cabinet or media box. It is commonly installed in whole-home air handler setups where a high-capacity, extended-surface pleated media is preferred over a 1-inch throwaway filter. HVAC technicians and service professionals install this filter during routine maintenance calls or when upgrading a system from lower-efficiency media.

Compatibility

Designed as an OEM-style replacement for residential and light commercial forced-air HVAC systems that accept a 24x24x4 inch nominal pleated media filter in a dedicated filter cabinet or media air cleaner housing.

Installation Notes

A licensed HVAC technician or qualified service professional should confirm actual filter cabinet dimensions before installation, using the actual size of 23.38 x 23.38 x 3.75 inches as the fit reference. Always power down the air handler or furnace at the disconnect or breaker before opening the filter cabinet. Install with the airflow arrow on the filter frame pointing toward the blower. Inspect and replace on a schedule appropriate to system runtime and local air quality conditions.
