In addition to improving indoor air quality, using an Aerostar furnace air filter helps to keep your HVAC unit working efficiently by removing dirt and reducing strain on the motor. This, in turn, leads to lower energy consumption, reduced maintenance requirements, and a longer unit life, ultimately saving you money on utility bills and maintenance costs.

Manufactured in the USA by Filtration Group, a world-leading manufacturer and supplier of filtration solutions, Aerostar filters are constantly innovating and improving their technology to make filtration more efficient, effective, and environmentally friendly.

Each box contains six Aerostar MERV 11 Pleated Furnace Air Filters, with a nominal size of 21 1/2x21 1/2x1 and an actual size of 21 1/2" x 21 1/2" x 3/4". These filters are designed to filter microscopic particles such as lint, dust mites, spores, pollen, pet dander, fine dust, and smoke, and are simple to install.

For best results, it is recommended to change your filters every 60 to 90 days, but you should increase the frequency to 30 days during peak summer and winter months. The filters are made of 100% synthetic electrostatic media for high efficiency with low air flow resistance, ensuring that they are both effective and cost-effective.
