Aerostar MERV 11 Pleated Air Filter, 20 x 21 1/2 x 1, Box of 4, Made in USA

The Aerostar 20x21 1/2x1 AC and Furnace Air Filter is a MERV 11 pleated filter designed to provide superior filtration efficiency. Manufactured in the USA by Filtration Group, a world-leading manufacturer and supplier of filtration solutions, this filter is comparable to MPR 1000 to 1200 and FPR 7 ratings.

The filter is made with electrostatically charged synthetic material that effectively draws and captures allergens between 1 - 10 microns, including lint, dust mites, spores, pollen, pet dander, dust, and smoke. This helps to improve indoor air quality and protect your family and loved ones from airborne allergens and particles that can trigger various allergy and asthma symptoms.

Changing the filter every 60 to 90 days during normal times of year, or more frequently (30 days) during peak summer and winter months when the HVAC unit is working the hardest, can help keep the unit running efficiently. This can reduce energy consumption, maintenance costs, and extend the overall lifespan of the HVAC system.

The Aerostar brand is known for its commitment to innovation and improving the effectiveness and environmental friendliness of its filtration solutions. The box contains four Aerostar MERV 11 Pleated Furnace Air Filters, with a nominal size of 20 x 21 1/2 x 1 and an actual size of 19 7/8" x 21 1/2" x 3/4".

In summary, the Aerostar 20x21 1/2x1 AC and Furnace Air Filter is a high-quality, MERV 11 pleated filter designed to provide superior filtration efficiency and improve indoor air quality. Its cost-effective and environmentally friendly design makes it a great choice for homeowners looking to maintain a healthier home environment.
