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!

Why is MERV Rating Important?

When you’re purchasing an air conditioner or furnace filter for your home, you want to be sure that you are buying a filter that will keep the air in your home clean. While all of our filters will provide you with the filtering efficiency needed to improve the air quality of your home, depending on the particular needs of your family, you may require a filter that has a higher MERV rating. Cases in which this is likely are those when you or someone in your home suffers from allergies, respiratory problems, or other similar incidences. Then again, you may just want to get the best filter for your family so that the indoor air quality around your home is the best it can be.

Below is a chart that will show you the efficiency of each MERV rating:
