Mpr micro particle performance rating.
Furnace filter merv vs mpr.
In other words popular brands are using their own rating systems to rate their filters.

Mpr microparticle rating is a rating system that includes microscopic particles not visible to the naked eye.
Whereas merv is a rating that can apply to all air filters mpr is a rating that was created by the company 3m and so it only applies to filters produced by the 3m brand.
Fpr filter performance rating.
Mpr ratings range from 300 mpr basic to 2800 mpr premium.
Their basic filter is rated at 100 and their most efficient filter is rated at 2800.
However of the three merv is the only one considered the industry standard.
Mpr measures ratings based on sizes 0 3 to 1 microns.
Mpr microparticle performance rating.
The others are proprietary names.
Mpr you should know that the one thing they all have in common is that all are different rating systems for hvac air filters.
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.
This rating system was developed by the company 3m designed to rate the manufacturer s filters and their ability to capture airborne particles smaller than 1 micron.
When it comes to the average home anything rated merv 7 to 12 is sufficient to filter airborne contaminants.
At 3m we believe merv only tells part of the story.
The mpr 2800 would qualify as a merv 14 so even though 3m emphasizes the smallest size range of particles their best filter doesn t qualify for the highest merv rating.
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.
