FAQ

Frequently asked questions regarding HVAC air filters and our filter delivery service.

 

What is a MERV rating? 

MERV stands for Minimum Efficiency Reporting Value. It basically is a measure of how effective your air filter is. MERV ratings can range from 1-16. The higher the rating, the smaller the particles your air filter will be able to clean.

 

Shouldn't I just use the highest MERV rating if I want the cleanest air?

Higher MERV ratings remove more harmful contaminants from your home, but they can also not work well with your HVAC system. Stronger MERV ratings do catch more particles due to their more dense nature, but this also can cause your system to work harder to circulate air. In some cases, your system may be unable to circulate air through certain filters. This will actually reduce the indoor air quality in your home.
