Aerostar 21 1/2 x 23 3/8 x 1 MERV 8 Pleated Air Filter, 4-Pack

Aerostar's 21 1/2x23 3/8x1 AC and Furnace Air Filter is designed to provide superior filtration efficiency and improve indoor air quality. Manufactured in the USA by Filtration Group, a leading provider of filtration solutions, these MERV 8 filters are comparable to MPR 600 and FPR 5 ratings.

Featuring 100% synthetic electrostatic media, the filters effectively capture microscopic particles such as lint, dust mites, spores, and pollen, while maintaining low air flow resistance. This helps keep your HVAC unit running efficiently, reducing energy consumption, maintenance costs, and extending its lifespan.

The nominal size of these filters is 21 1/2x23 3/8x1, with an actual size of 21 1/2" x 23 3/8" x 3/4". This makes them a simple and cost-effective solution for protecting your family and loved ones from airborne allergens and particles that can trigger various allergy and asthma symptoms.

Aerostar is known for constantly innovating and improving their filtration technology to enhance efficiency, effectiveness, and environmental friendliness. By changing the filters every 60 to 90 days during normal times of year, and increasing the frequency to 30 days during peak summer and winter months, you can ensure your HVAC system operates at its best, while maintaining a healthier home environment.

The box contains four Aerostar MERV 8 Pleated Furnace Air Filters, providing a convenient and hassle-free way to maintain your indoor air quality. As a trusted brand in the filtration industry, Aerostar offers a reliable and sustainable solution for your home's air filtration needs.
