MERV 11Air Filters

Measuring and Replacing Your Air Filters

MERV 11 synthetic media (comparable with MPR 1000-1200 & FPR 7) is recommended if you have additional filtration needs because of factors like pets or allergies with its capability to defend against 95% of airborne particles, protecting your home or business from smoke, smog, debris, lint, pollen, mold, dander, and other forms of dust without impacting air flow.

As the filtration (MERV) rating increases, so does its ability to capture finer particles from the air. MERV 8 air filters are our best sellers, as they offer professional protection at a reasonable cost, meaning they will be more than sufficient in almost every scenario. Upgrading to a MERV 11 or MERV 13 air filter will provide extra levels of efficiency that may be preferred in certain situations. Choosing a MERV 11 filter can better help combat allergies while MERV 13 alternatives are strong enough to trap bacteria. At the end of the day, all three filtration ratings will work with your system, so picking the right one just depends on your lifestyle and air quality needs.

All air filters have a nominal size and an actual size. The nominal size is a shorthand number rounded to the nearest whole or half inch, normally in a larger font, that helps simplify the purchasing process (ex: 20" x 20" x 1"). Whereas the actual size is an exact measurement, usually in a smaller font, that depicts the precise dimensions of the filter (ex: 19.5" x 19.5" x .75").


If your current air filter does not have a dimension listed on the frame, grab a tape measure, and record the height x length x widthto find the actual size. You can then round these measurements up to the nearest inch to find a corresponding nominal size, which will be easier to locate when searching online.

As a rule of thumb, we recommend replacing your filter every 90 days to keep your system running efficiently and your air clean. However, this is subject to change depending on the filter size as well as other variable factors for pet owners, allergy-sufferers, households with children, etc.


Once you receive your new filter, installation is made simple with the inclusion of easy-to-understand arrows on the frame that help identify the direction of air flow and subsequently the way the filter needs to be placed.
