MERV Rating Explained

Minimum Efficiency Reporting Value (MERV).

Other common ratings found within certain brands and stores includes FPR, MPR. They all follow the same basic principal, the higher the number the greater overall effectiveness of the air filter.

FPR - filter performance rating, labels filters based on a number scale from 4 through 10 in addition to a color-coding system. Designed by The Home Depot for brands sold through their stores, including Honeywell, this rating structure is very similar to MERV rating. At the end of the day it adds more confusion and is a way for HD to get customers to only use The Home Depot sold filters.

Other common ratings found within certain brands and stores includes FPR, MPR. They all follow the same basic principal, the higher the number the greater overall effectiveness of the air filter.

MPR, or micro-particle performance rating was developed by 3M. It rates the 3M Filtrete filters and their ability to capture airborne particles smaller than 1 micron. While MERV ratings reflect a filter's ability to trap both microscopic and macroscopic particles, MPR ratings only grade a filter on its capacity to remove particles from 0.3 to 1 microns.

Minimum Efficiency Reporting Value, or MERV for short, is a filter rating system devised by ASHRAE, the American Society of Heating, Refrigeration and Air Conditioning Engineers, to standardize and simplify air filter efficiency ratings for the public. The higher the MERV rating, the higher the effectiveness of the air filter

Microparticle  Performance Rating, or MPR for short, is a filter rating system developed by 3M to rate a filters ability to cature the smallest airborne particles. The higher the MPR rating the better the filters ability to capture particles from the air. This system helps in comparing 3M filters, but is not directly comparable to the MERV rating system.

If your filter at home is rated by the MPR system, here is a table to show you what the comparable MERV rating would be.

MPR - Comparable MERV

300....................6
600....................8
1000..................11
1200..................11
1500..................12
1900..................12
2200..................12

MERV ratings help you choose the right filter for your needs by indicating how effectively a filter can remove airborne particles.

If considering making the switch from a basic fiberglass style filter to a pleated with a MERV rating. We always recommend going with a filter like a MERV 8 to start. See how your systems does with a pleated MERV 8 before making the jump to a higher rating like a MERV 13. Since every system is different we always recommend contacting a local technician if you have concerns.

MERV 1-4 filters capture large particles like dust and lint, while higher MERV ratings capture smaller particles, including allergens and bacteria.

Yes, higher MERV ratings capture smaller and more particles, improving indoor air quality.

Potentially, yes. Higher MERV filters can restrict airflow, so ensure your system can handle it before upgrading.

Yes, MERV 8 filters capture common allergens like pollen and mold spores, making them suitable for allergy sufferers.

MERV 11 filters capture finer particles such as pet dander and dust mites, providing better air quality for homes with pets or allergy sufferers.

MERV 13 filters capture very fine particles, including smoke, bacteria, and some viruses, offering superior air quality.

Standard MERV filters do not typically remove odors, but some specialized filters can help reduce them.

Check your filter every month. If it looks dirty or clogged, it’s time to replace it. Follow the recommended replacement schedule.

HEPA filters have higher efficiency than MERV filters and are capable of capturing 99.97% of particles as small as 0.3 microns.

For most homes, a MERV 8-11 filter is sufficient to improve indoor air quality without overworking your HVAC system.

Yes, but check with your HVAC manufacturer to ensure your system can handle the increased airflow resistance.

Yes, MERV filters are available for both furnaces and air conditioning systems, improving air quality throughout your home.

No, MERV filters are typically easy to install, and you can replace them yourself by following the manufacturer’s instructions.

Yes, higher MERV rated filters can capture airborne irritants and allergens, potentially reducing asthma symptoms.

For commercial buildings, MERV 8-13 filters are typically recommended to ensure good indoor air quality and efficient HVAC operation.

Yes, by improving indoor air quality, MERV filters can help reduce sick days and increase overall productivity.

In industrial settings, higher MERV rated filters can protect sensitive equipment from dust and other airborne particles, enhancing system performance and longevity.

Yes, MERV 13 filters and higher are often used in healthcare settings to capture fine particles, including bacteria and viruses, ensuring a sterile environment.

Using MERV filters in schools can improve air quality, reducing the spread of illnesses and providing a healthier environment for students and staff.

Yes, industrial settings with higher levels of airborne particles may require more frequent filter changes to maintain optimal air quality and system performance.

Yes, using appropriate MERV rated filters can help businesses comply with industry air quality standards and regulations.
