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.
Air filter merv rating vs mpr.
It is an acronym for high efficiency particulate air filter as officially defined by the u s.
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.
Merv stands for minimum efficiency reporting value.
The range is from 1 lowest efficiency to 20 highest efficiency.
What is the difference between merv mpr and fpr air filter ratings.
See why the mpr system is superior to the industry standard.
A merv rating chart shows a numerical value.
All filters sold must meet basic safety expectations and most brands have higher level filters to address particular needs and situations.
The three rating systems were created by separate organizations.
See screenshot below this filter for sale on the home depot shows fpr 10 as equivalent to either merv 8 or merv 13.
Use this rating system compare filters made by different manufacturers.
Mpr microparticle performance rating.
Merv 17 through merv 20 filters are typically used in surgical operating rooms.
Mpr measures ratings based on sizes 0 3 to 1 microns.
Mpr ratings range from 300 mpr basic to 2800 mpr premium.
Merv ratings extend from 1 to 16.
This is an industry standard rating system.
Mpr microparticle rating is a rating system that includes microscopic particles not visible to the naked eye.
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.
The merv filter rating is the domestic and international industry standard rating system established by the.
Fpr ratings are on a scale from 4 through 10.
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.
Hepa is a type of pleated mechanical air filter.
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.
Mpr rating scales filter rating scales indicate not only the quality or the air filtration but also the specific types of particles removed.
Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings.
At 3m we believe merv only tells part of the story.
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.
The three air filter rating systems differ in ranges and were created by separate organizations.
This rating system reports how well the filter captures and holds.
