What Are the Differences Between Each MERV Ratings?

MERV Rating

Our HVAC professionals know the importance of using a good air filter. Before you purchase an air filter, you need to understand the MERV rating system. The numbers describe the quality of the air filter. The ratings are divided into separate categories. You may need a MERV 1 filter if you have moderate allergies. A MERV 16 filter is ideal for severe respiratory issues. If you do not have any health issues, you may not need an expensive filter. The most expensive filters can remove tiny particles from the air. The rating system will help you choose a filter that is ideal for your home.

MERV 1-4

  • Filters in this category can remove large particles.
  • They are usually the most inexpensive option.

MERV 5-8

  • Filters in this category are slightly better than MERV 1-4 air filters.
