What is MERV Rating?

Top 3 Reasons Why MERV is Important

You may have heard a lot of buzz about MERV in your search for air and furnace filters, but what is a MERV rating exactly? First off, MERV stands for:

  1. The higher the MERV rating on a filter, the fewer dust particles and other contaminants can pass through it. What does this mean for you? As a homeowner, you want to be sure your family is safe and healthy, right? Well, changing your filters regularly will certainly help with that, but the MERV rating on the filters you buy is also important.
  2. MERV ratings dictate the price you pay. While you may think on the surface that MERV 11s are inherently better than MERV 8s, you may be wrong. This isn’t always the case – in fact, it may all depend on where you buy them! Learn more about MERV 8 vs MERV 11
  3. For optimal home comfort, adequate airflow is necessary to regulate temperature and keep allergens out. For most homes, a MERV rating between 8 and 11 is perfectly fine. Higher MERV ratings may be more desirable to you if you have family members, particularly children and older folks, who suffer from allergies and asthma.

Doing your research on any filter before you buy it is imperative. According to the United States Environmental Protection Agency, medium efficiency filters with a MERV rating between 8 and 11 are reasonably efficient at filtering small to large airborne particles.

The Bottom Line

Considering the MERV rating on your air or furnace filters in Canada is a helpful way to identify the capabilities of different large air cleaners. Determined through rigorous testing and given the worst-case performance of the filter, the MERV number remains true and uninflated, providing a good indicator of performance. That being said, there are other factors at play here as well, so don't assume that buying the right air filtration system is a simple matter of choosing the unit with the highest MERV. For example, most brands out there today use electrostatic charges to boost the filter's rating. However, like a balloon that you rub on your head and place on the wall, that charge will only last a few hours. Same with filters: the electric charge eventually dissipates and reduces the filter's efficiency after just a few hours of operation within a system. The MERV 8 30/30, however, is a mechanical vs. electrostatic filter, meaning it will retain its efficiency consistently over time.
