Each filter measures 20 inches x 25 inches x 2 inches and is designed to capture airborne allergens including pollen, mold spores, and dust mite debris from residential forced-air HVAC systems. The 1000 MPR rating positions this filter between standard fiberglass media and high-efficiency MERV-rated hospital-grade units, making it a practical choice for residential systems where occupant allergy concerns are a priority without over-restricting airflow.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential split systems, heat pumps, and gas or electric forced-air furnaces that accept a 20 x 25 x 2-inch filter size.
