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.

Air Filter

Will be installed tomorrow. I am almost 90 and putting things together is not as simple as it used to be. Serve person will tell me if it is correct. No comment on effectiveness yet.

Top notch filters

Service is always a plus. Received my order pretty fast. At first, I didn’t like the idea of assembling them myself but as it turns out it’s pretty easy. Instructions are right on the filter. Been getting my filters from Air Filters Unlimited for years. Highly recommend.
