Our MERV 11 air filters are a great upgrade from MERV 8 air filters if you have pets in your home or suffer from allergies or asthma. These air filters are 85% efficient at capturing particles in the 3-10 micron range and up to 80% efficient at capturing particles in the 1.0-3.0 micron range. The filter frame is constructed of heavy-duty beverage board to insure it maintains its integrity for the duration of its service life. The pleated media won't support microbial growth due to its 100% synthetic construction. Our MERV 11 air filters last up to 90 days depending on the conditions in your home. Check out our "Air Filter Change Frequency" page for additional information.

Ok I guess. My husband changes out the used filter and replaces it with a new one and the A/C works fine. Your price is better than those locally.

Experience ok, but I should have bought Merv 8. Much cheaper and fine for my house.

OEM Air Filter at Discount prices

Overall the experience was good. Be sure to orient the two pieces properly so you can engage each of the tabs. This will give great stability, once fully assembled. I have been buying these the last two to three years and they work just as good as the more expensive comparable filters from the dealer.
