Aerostar MERV 8 Pleated Air Filters, 6 Pack (Various Sizes)

Aerostar 20x25x4 MERV 8 Pleated Air Filters (Actual Size: 19 1/2"x 24 1/2" x 3 3/4") - 6 Pack are designed for superior filtration efficiency. These filters are made with electrostatically charged synthetic material that draws and captures allergens between 0.3 - 1.0 microns, including lint, dust mites, mold spores, and pollen. Aerostar filters are a simple and cost-effective step towards a healthier home environment, free of airborne allergens and particles that can trigger various allergy and asthma symptoms. They also improve the efficiency of your HVAC unit and therefore reduce maintenance and utility costs by removing dirt and reducing strain on the motor. For best results, change the filter every 60 to 90 days, but increase frequency to 30 days during peak summer and winter months when your unit is working the hardest. Aerostar 16x20x1 MERV 8 Pleated Air Filters (Actual Size: 15 3/4"x 19 3/4" x 3/4") - 6 Pack are also designed for superior filtration efficiency, using the same electrostatically charged synthetic material. These filters are compatible with furnaces and AC units, and are a simple and cost-effective step towards a healthier home environment. For best results, change the filter every 60 to 90 days, but increase frequency to 30 days during peak summer and winter months. Both the 20x25x4 and 16x20x1 MERV 8 filters are comparable to MPR 600 and FPR 5, and feature 100% synthetic electrostatic media for high efficiency with low air flow resistance.
