It is an acronym for high efficiency particulate air filter as officially defined by the u s.
Air filter merv rating vs mpr.
This type of air filter can theoretically remove at least 99 97 of dust pollen mold bacteria and any airborne particles with a size of 0 3 microns µm.
At 3m we believe merv only tells part of the story.
Merv ratings extend from 1 to 16.
Mpr measures ratings based on sizes 0 3 to 1 microns.
Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings.
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.
Mpr rating scales filter rating scales indicate not only the quality or the air filtration but also the specific types of particles removed.
Mpr microparticle performance rating.
Mpr microparticle rating is a rating system that includes microscopic particles not visible to the naked eye.
See screenshot below this filter for sale on the home depot shows fpr 10 as equivalent to either merv 8 or merv 13.
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.
Hepa is a type of pleated mechanical air filter.
Fpr filter performance rating.
Mpr ratings range from 300 mpr basic to 2800 mpr premium.
This rating system reports how well the filter captures and holds.
The merv filter rating is the domestic and international industry standard rating system established by the american society of heating refrigerating and air conditioning engineers.
The merv filter rating is the domestic and international industry standard rating system established by the.
Use this rating system compare filters made by different manufacturers.
The three rating systems were created by separate organizations.
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.
Fpr ratings are on a scale from 4 through 10.
The range is from 1 lowest efficiency to 20 highest efficiency.
Merv stands for minimum efficiency reporting value.
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.
