Furnace Filter Ratings Merv Vs Mpr

When it comes to the average home anything rated merv 7 to 12 is sufficient to filter airborne contaminants.

Furnace filter ratings merv vs mpr.

Learn the differences between merv mpr fpr to choose the best filter for your needs. Mpr micro particle performance rating. Their basic filter is rated at 100 and their most efficient filter is rated at 2800. For example a merv 4 filter removes dust lint and pollen.

The mpr scale however uses much larger numbers. Scientists at 3m believe that merv only tells part of the story. 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. It s why we created a different measurement microparticle performance rating mpr.

Microparticles are not even measured on the merv scale until it reaches merv 11. Fpr rating systems air filter ratings explained. This rating includes microscopic particles not visible to the naked eye. For reference a typical dust particle is between 2 and 8 microns while pollen starts at 7 microns and can get up to 70 microns in size.

Exclusive filtrete brand filter technology focuses on capturing the tiniest particles between 0 3 and 1 micron µm in size. However a merv 13 filter removes those as well as dust mites mold pet dander smoke smog viruses bacteria and more. What is the difference between merv mpr and fpr air filter ratings. While merv ratings reflect a filter s ability to trap both microscopic and macroscopic particles mpr ratings only grade a filter on its capacity to remove particles from 0 3 to 1 microns.
