Is MERV 11 the Right Air Filter for You?

Learn about how MERV 11 air filters can help improve indoor air quality in your home by removing 85% of micron-sized pollutants.

Is MERV 11 the Right Air Filter for You?

MERV 11 air filters are designed to capture a wide range of particles, from pollen and dust mites to smoke, pet dander, smog, car emissions, bacteria and other fine particles. This type of filter has a higher efficiency rating than MERV 8 filters, meaning it can capture smaller particles and remove more pollutants from the air. But is MERV 11 the right filter for your needs? The MERV 11 filter is ideal for pet owners and people with mild allergies or asthma. It offers more filtration than the MERV 8, but not as much as the MERV 13 (the highest option suggested for residential use).

MERV 11 filters are more efficient than MERV 8 filters because they can capture smaller particles. They provide additional protection against pet dander, dust mites, self-emissions, and dust that can damage the lungs. This is a great option for homes with pets or those looking for improved air quality than what the MERV 8 can provide. It's also our most popular type of air filter.

The MERV 11 will increase indoor air quality by removing 85% of micron-sized air pollutants, while maintaining the efficiency of the HVAC unit. Filter technology has advanced significantly over the years, and MERV ratings are designed to help us determine the most effective and efficient air filter options for heating and cooling systems and more. MERVs 14 to 20 are best for hospital and laboratory applications where as much of the air needs to be captured as possible. If your home's HVAC system is not capable of handling MERV 13, opt for a filter with the next highest possible rating.

While MERV 8 is known to be effective at filtering contaminants such as pollen, dust mites, sawdust, mold spores, and lint from the air, higher MERV ratings will clean the air even more effectively. Technology for HVAC units has progressed since then and most modern units in recent years should be able to have a MERV 8 filter at least.MERV 11 air filters can filter a large percentage of fine particles, but a MERV 8 air filter cannot. The lowest ratings, MERV 1 - 8, are the least efficient at filtering particles, but they do allow the lowest air resistance. If you want it to at least clean the air and handle dust, mold, pollen and bacteria, then a MERV 8 will do the job.

The same applies to homes with smokers or pets, as MERV 11 air filters better eliminate odors.The higher the MERV rating, the greater the overpressure or air resistance the filter could put in your HVAC system. Filter King offers a hassle-free MERV 11 air filter subscription service, so you never forget to replace your air filters.


, also known as the Minimum Efficiency Report Value, is a system used to evaluate the efficiency of an air filter based on its effectiveness in capturing particles of different sizes. Low-efficiency filters are generally within MERV 1-4 and high-efficiency filters are MERV 13 and later.Each air filter has its advantages and disadvantages, but both MERV 8 air filters and MERV 11 air filters are suitable for residential use.

Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in a home without affecting airflow.
