The Aerostar 20x22x1 MERV 11 Pleated Air Filter is designed for use with furnaces and air conditioning units. This pack has a nominal size of 20x22x1, with an actual size of 19 3/4" x 21 3/4" x 3/4".

The MERV 11 filter is comparable with MPR 1000-1200 and FPR 7. It is made with 100% synthetic electrostatic media designed for high efficiency with low air flow resistance.

The electrostatically charged synthetic material draws and captures allergens between 0.3 and 1.0 microns, including lint, dust mites, spores, pollen, pet dander, fine dust, and smoke.

The filter is designed for simple installation and provides a cost-effective step toward a healthier home environment. Changing the filter every 60 to 90 days, with replacement every 30 days during peak summer and winter months when the HVAC unit is working hardest.
