What Does MERV Rating Mean?

What is a MERV Rating?

MERV stands for Minimum Efficiency Reporting Value and is the primary rating system used for air filtration in the United Stated and around the world. It is designed to measure a filter’s ability to capture and hold particles and pollutants. The higher the MERV rating, the more particles - dust mites, pet dander, air allergens, etc - your filter will capture.

Matching the right MERV rating to your needs will improve your home's air quality and will extend the life of your furnace or air conditioner.

The MERV Ratings are as follows:

  • MERV 6: Change every 30 Days
  • MERV 8: Change every 60-90 Days
  • MERV 11: Change every 60-90 Days
  • MERV 13: Change every 60-90 Days
