MERV 11 Air Filters


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.
