AF24x24x4N-M8 Pleated Air Filter Merv 8

Product Description

The AF24x24x4N-M8 is a MERV 8 pleated air filter designed for residential and light commercial HVAC systems. Rated at MERV 8, it captures a broad range of airborne particles including dust, pollen, mold spores, and pet dander, making it a solid general-purpose choice for forced-air heating and cooling systems. The nominal size is 24x24x4 inches with an actual size of 23.375 x 23.375 x 3.75 inches. Licensed HVAC technicians and knowledgeable homeowners install this filter during routine maintenance intervals to maintain system airflow and indoor air quality.

This filter is suited for standard residential furnaces, air handlers, and central air conditioning systems that accept a 4-inch deep filter slot in a 24x24 nominal opening. The pleated media design provides greater surface area than flat panel filters, extending service life while maintaining consistent static pressure across the filter face. It is commonly installed in return-air filter grilles or filter cabinets as part of scheduled preventive maintenance.
