When looking for quality air filters, you may see different abbreviations on the filters and start getting confused about what they all mean. Here at FilterTime, we want to ensure you understand the breakdown and what all those abbreviations mean.

MERV Rating

It is an abbreviation for Minimum Efficiency Reporting Values. The MERV rating system has a range of 1 to 16. MERV rating 1 is the lowest efficiency with minimum filtration in your filters up to 16 which is the highest efficiency and filtration.

To learn more about which MERV rating is best for your home depending on the time of year, allergies, and prone to illness, please review our breakdown of MERV ratings from our article - “What are MERV Ratings?” 

MPR Rating

This isn’t Minnesota Public Radio, instead, it’s another rating. It is the Microparticle Performance Rating. This rating includes the microscopic particles not visible to the naked eye. These particles aren’t measured on lower-rated MERV filters. This is a newer rating to help ensure your filters run at the highest quality.

If you are prone to allergies, the higher the rating the better.

FPR Rating

This is the filter performance rating. This is a specific performance rating developed by 3M for specific filters sold by Home Depot. It is very similar to MERV rating system. Essentially for this filter system, they look at how well a filter catches both large and small particles and rank the filters on a 1 to 10 scale.
