When the air filter is clogged, your HVAC system will strain harder to remove dirt, dust and debris present in your indoor air, resulting in increasing your utility bills and shortening your HVAC equipment’s life. So, it’s important to routinely monitor them. Replacing a furnace filter regularly not only maximizes the efficiency of your heating and cooling system, but also help purify your home’s air.

Merv Filters LLC 12x12x1 MERV 11 furnace filter is effectively designed to remove 91% of airborne particles, including dust mites, pollen, mold spores, pet dander, dust, and smog. Served in a pack of 4, 6, 12 filters. Our pleated high-capacity filters are made by using electrostatically charged filter media that captures even smaller particles of 1-10 microns in size, making 12x12x1 MERV 11 filter an ideal choice for homeowners living with pets, especially cats.

Important Note: When it comes to replacing 12x12x1 MERV 11 air filter, make sure you get the right size filter, as our filters are sold by their rounded up number referred to as nominal size, which is labeled on filter packages. The nominal size is a bit greater than the actual size. If the ‘nominal’ size of the filter is 12x12x1, then the ‘actual’ size is 11.5×11.5×0.75
