What is MERV rating?
MERV, which stands for Minimum Efficiency Reporting Value, is a rating that was developed by ASHRAE (the American Society of Heating, Refrigerating, and Air-Conditioning Engineers) and it is used to assess the filtering power of an air conditioner or furnace filter.
The MERV scale consists of ratings from 1 to 16, with filter performance being greater as the number increases. On the MERV scale, dirt particles are graded from 0.3 microns to 10 microns.
A micron is 1 millionth of a millimeter, and just to give you an idea of just how small that is, you can look at the size of a single human hair.
The average strand of human hair is about 100 microns thick, so imagine just how small 0.3 microns of dirt is!
MERV rating efficiency chart:
|MERV Rating||Average Particle Size||Efficiency in Microns|
|MERV 1-4||3.0-10.0||less than 20%|
|3.0-10.0||85% or greater|
|3.0-10.0||90% or greater|
|1.0-3.0||90% or greater|
|MERV 16||0.3-1.0||75% or greater|
