Your cart is empty.Aerostar 20x20x1 MERV 13 Pleated Air Filters (Actual Size: 19 3/4" x 19 3/4" x 3/4") - 4 Pack. MERV 13 filters are comparable to MPR 1500-1900 and FPR 10. 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, spores, pollen, pet dander, fine dust, smoke, viruses, and bacteria. 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. Compatible with furnaces and AC units.

Seems to be a little bit of overkill in my old system - doesn't blow as much air. Next time I'll try something a little cheaper.

I use these to make an air filter for my home. I sleep well knowing that it is scrubbing the air clean.It works very well. If you like to use candles or aromatherapy, this filter will actually clean the fragrance out of the air.

I use these filters for my box fan/air filter. They work quite well in eliminating odors, smoke from cooking and particulates from the air.

These filters are comparable to Filtrete brand at a more reasonable cost. I have dogs in the home so the filters must be changed more often. Happy with these.

I recently moved into an apartment. The people who lived here before had a short haired dog. I have allergies. The place smelled like dog and I was experiencing congestion. After extensivly vacuuming and scrubbing the carpets, I added these filters to the air system. The place smells like a normal home now and my allergies have been relieved. Each day is better. MERV 13 filters are designed with pet dander and other tiny allergens in mind. I'm happy I tried these. They make a difference.
