Why Are Air Filters Rated?

The quality of an air filter is assessed by its rating, which tells you lot what capacity the filter has in blocking our particulates in the air. The higher the rating (for MERV, FPR, and MPR), the smaller the air and dust particles your home ac air filter can capture.

Without a standardized air filter rating method, homeowners and other HVAC enthusiasts are left in the dark on how well their air filter works confronting a wide range of airborne particles, including:

Dust
Pollen
Smoke
Pet dander
Hair
Odors
Bacteria
Airborne viruses

When it comes to assessing air filter filtration capacity, nosotros use a term "micron" which allows us to know how the smallest size of particle that an air filter can block.

Micron sizes tin can range anywhere from microscopic to visible to the man centre. Here's a handy chart to give y'all an idea of the range of micron sizes:

different micron sizes for air particulates - filterbuy

It's important to annotation that anything in the size range between .001 microns and 10 microns can reach deep into the lungs past being inhaled. Any particulates nether effectually 100 microns can actually be inhaled into the nose.

The MERV, MPR, and FPR rating systems each consist of a range of numbers that stand for the filtration effectiveness based on the micron size that it can filter out. Beneath, nosotros'll interruption down where the rating systems come from and how to utilize them when shopping for your next filter.

MERV Air Filter Ratings

MERV stands for "Minimum Efficiency Rating Value."

Every air or furnace filter in the US carries a MERV rating, which is the only nationally regulated rating system for air filters. Established past the ASHRAE (American Social club of Heating, Refrigerating, and Air Conditioning Engineers), the MERV rating system specifies a filter'southward ability to capture air particles and pollutants.

MERV ratings run on a ane-20 scale that designates the effectiveness of filters to capture certain particle sizes. The higher the MERV rating, the more particles it captures.

If the MERV rating is too high (to a higher place MERV 13), however, it can increase organization backpressure and cake air flow through your primal air system, worsening the effectiveness of your HVAC system.

MPR Air Filter Ratings - Microparticle Operation Rating

MPR stands for "Microparticle Performance Rating."

Created by 3M, only filters designed by the 3M/Filtrete make comport an MPR rating, which rates the filter'due south power to trap air particles smaller than one micron. MPR ratings range from 300 MPR (Basic) to 2800 MPR (Premium).

Below is a chart showing the MPR rating organisation:
