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 grit particles your home ac air filter can capture.

Dust
Pollen
Fume
Pet dander
Hair
Odors
Bacteria
Airborne viruses

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

Micron sizes can range anywhere from microscopic to visible to the man eye. Here's a handy nautical 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 tin can reach deep into the lungs by being inhaled. Whatsoever particulates under effectually 100 microns tin can actually be inhaled into the olfactory organ.

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

MERV ratings run on a 1-20 calibration that designates the effectiveness of filters to capture sure particle sizes. The college the MERV rating, the more particles information technology captures.
