At 3m we believe merv only tells part of the story.
Air filter merv rating vs mpr.
Mpr microparticle rating is a rating system that includes microscopic particles not visible to the naked eye.
Mpr ratings range from 300 mpr basic to 2800 mpr premium.
Mpr rating scales filter rating scales indicate not only the quality or the air filtration but also the specific types of particles removed.
The range is from 1 lowest efficiency to 20 highest efficiency.
Mpr measures ratings based on sizes 0 3 to 1 microns.
Use this rating system compare filters made by different manufacturers.
The three air filter rating systems differ in ranges and were created by separate organizations.
Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings.
Created by 3m only filters designed by the 3m filtrete brand carry an mpr rating which rates the filter s ability to trap air particles smaller than 1 micron.
Hepa is a type of pleated mechanical air filter.
It is an acronym for high efficiency particulate air filter as officially defined by the u s.

The merv filter rating is the domestic and international industry standard rating system established by the.
Filters with a merv rating of 1 4 mostly filter out dust lint and pollen among other larger common particles they do very little to trap small microparticles.
See why the mpr system is superior to the industry standard.
This rating system reports how well the filter captures and holds.
Fpr filter performance rating.
Fpr ratings are on a scale from 4 through 10.
In general filters with a rating of merv 16 or below are considered to be hvac system grade filters for residential commercial and general hospital use.
What is the difference between merv mpr and fpr air filter ratings.
Merv stands for minimum efficiency reporting value.
When you want the best possible air filter for your home microparticles matter most they make up 99 of the particles that are in the air.
Some filters on their website that have both an fpr and a merv rating and at least one with an fpr of 10 is shown as equivalent to either merv 8 or merv 13.
