The Aerostar MERV 11 Pleated Air Filter (19 7/8 x 21 1/2 x 1) is engineered to filter out microscopic particles and allergens that can affect your health. With a nominal size of 19 7/8 x 21 1/2 x 1 and an actual size of 19 7/8" x 21 1/2" x 3/4", this filter is designed to fit most standard HVAC systems. The electrostatic media captures particles as small as 0.3 microns, including lint, dust mites, spores, and smoke, making it ideal for allergy sufferers. For best results, change the filter every 60 to 90 days; during peak seasons, increase the frequency to every 30 days. This filter not only improves air quality but also enhances the efficiency of your HVAC unit by reducing strain on the motor, ultimately lowering your utility bills.
