Choosing a MERV 11 Air Filter

Choosing a MERV 11 air filter is easy if you know how to compare the nominal and actual size of an air filter. The nominal size is often rounded, and the actual size is in smaller print, usually in parenthesis. Typically, a MERV 11 air filter will last three months, which is about three times longer than the average fiberglass filter. However, it is important to know how to choose a MERV 11 to get the most effective performance.

The MERV rating of an air filter refers to its efficiency at trapping small particles. The MERV rating is based on the effectiveness of the filter against twelve different sized particles that are created in a laboratory. The smallest particles can be as small as a human hair, or 50 um. These filters are divided into three different sizes, with E1 covering particles 0.3 to 1.0 um, and E2 encompassing particles from three to 10 microns.

MERV ratings are determined by testing the effectiveness of air filters on 12 different sized particles. The size of a human hair is fifty um, while the smallest particles recognizable by the human eye are forty um. The filter is rated according to its effectiveness in trapping these tiny particles and preventing them from reaching the air in your home. A MERV 11 air filter should be used in your home to reduce the effects of smog, auto emissions, and pet dander.

When buying a new air filter for your home, remember that a MERV 11 rating is not too high for residential use. Generally, a MERV 13 filter is sufficient to trap most of the airborne contaminants without affecting the airflow in your home. Those with a higher MERV rating should be used for commercial HVAC systems. But this is not always the case. If you are looking for a high-quality, long-lasting air filter, you might want to go for a MERV 11 one.

MERV 11 filters are the highest-quality filters, but the higher MERV number will require a more expensive filter. But, they will help you save money in the long run. By limiting the number of particles in your air, you will be able to reduce the cost of heating and cooling systems. This will also make your home safer as you won’t have to worry about the safety of your family.

MERV 11 air filters are excellent for residential applications, as they are highly effective at trapping dust, pollen, pet dander, and odors. These filters can also be used in commercial buildings to improve the indoor air quality. Regardless of your home’s size, a MERV 11 filter will improve the quality of your air.
