Furnace filter merv vs mpr.
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 you should know that the one thing they all have in common is that all are different rating systems for hvac air filters.
The others are proprietary names.
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.
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 micro particle performance rating.

Fpr filter performance rating.
Mpr stands for microparticle performance rating and as the name suggests it rates the filter s ability to filter out micro particles.
At 3m we believe merv only tells part of the story.
When it comes to the average home anything rated merv 7 to 12 is sufficient to filter airborne contaminants.
