MPR stands for Microparticle Performance Rating, and it’s how Filtrete™ Brand reports a filter’s ability to pull in and trap tiny particles between 0.3 and 1 micron in size. For reference, an average strand of human hair is about 70 microns in size.
What is a good MPR rating?
A good MPR rating to start at is MPR 600. Filters with an MPR 600 rating strike a good balance between filtration efficiency and airflow. If you are susceptible to allergens such as fine dust or pollen, moving up to an MPR 1000 filter is the next step in air filtration efficiency.
Is MPR or MERV better?
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.
What is a good MERV rating for air filters?
We do recommend that everyone uses filters that have at least an 8 MERV rating. These filters will remove the majority of pollutants from your indoor air. If you have serious medical conditions making it difficult to breathe, you might want to get a filter with MERV 9-12 rating.
