What is MERV rating?
Contents
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% |
| MERV 6 | 3.0-10.0 | 49.9% |
| MERV 8 | 3.0-10.0 | 84.9% |
| MERV 10 | 1.0-3.0 | 50%-64.9% |
| 3.0-10.0 | 85% or greater | |
| MERV 12 | 1.0-3.0 | 80%-89.9% |
| 3.0-10.0 | 90% or greater | |
| MERV 14 | 0.3-1.0 | 75%-84.9% |
| 1.0-3.0 | 90% or greater | |
| MERV 16 | 0.3-1.0 | 75% or greater |
Why is MERV Rating Important?
