MERV 11 air filters are designed to capture pollen, dust mites, pet dander & other fine particles from the air. Learn how they help improve indoor air quality.

What is a Merv 11 Filter and How Does it Help Improve Air Quality?

MERV 11 air filters are designed to capture a wide range of pollutants, from pollen and dust mites to pet dander and car emissions. With a higher efficiency rating than other filters, MERV 11 filters can trap finer particles and remove more pollutants from the air. But is the MERV 11 too tall for your needs?The Minimum Efficiency Values (MERV) indicate the ability of a filter to capture larger particles between 0.3 and 10 microns (µm). All air filters require regular cleaning and filter replacement to work properly.

A MERV 11 filter is capable of trapping all of these substances, in addition to pet dander, smoke, smog, and airborne particulates produced by coughing and sneezing. It is an ideal choice for those with children or pets, as it will filter many of the most common air pollutants and irritants. Allergy sufferers should also consider investing in a MERV 11 filter. In the usual cases, a MERV 8 air filter is considered a more than adequate option. However, it may not be enough when it comes to combating the increase in outdoor air pollution, pet fur and dander, or the triggers of asthma and allergies.

Although the ratings don't exceed those of the MERV 16, high-efficiency particulate air (HEPA) filters trap the smallest particles at a faster rate than even the MERV 16 and are typically used in surgical operating rooms, clean rooms, and other contexts that require absolute cleaning. The MERV 11 will increase indoor air quality by eliminating 85% of air pollutants the size of a micron, thus maintaining the efficiency of the air conditioning unit. Filter King offers a simple subscription service to the MERV 11 air filter so you never forget to change them. MERV 11 air filters block at least 65% to 79% of airborne particulates in a size range of 1.0 to 3.0 microns. Newer units shouldn't have airflow problems with higher MERV ratings, although older models can work harder with a MERV 13 filter installed than when they originally had a MERV 6 filter in the air intake. In these cases, a MERV 11 air filter can offer additional benefits and capture a wider range of particles that would pass through a MERV 8 filter. If someone has an allergy or a respiratory problem, opt for a MERV 11 air filter or even a MERV 13 air filter.

Using an air filter with a MERV rating that is too high is just as bad as using one that is too low. While MERV ratings reflect a filter's ability to trap microscopic and macroscopic particles, MPR ratings only qualify a filter based on its ability to remove 0.3 to 1 micron particles. Air filters with higher MERV ratings may filter more but the thickness of the filter material may restrict airflow. It is important to follow the manufacturer's recommendations on maintenance and replacement for your specific unit in order to ensure optimal performance.
