When it comes to maintaining a healthy and comfortable indoor environment, your HVAC system’s air filter plays a crucial role. At Grissom Service Company, we often encounter homeowners who are confused about MERV ratings and their importance in air filtration. Let’s dive into this topic and help you make an informed decision for your home.

What is a MERV Rating?

MERV stands for Minimum Efficiency Reporting Value. It’s a standardized rating system that measures an air filter’s effectiveness in trapping particles of various sizes. The scale ranges from 1 to 20, with higher numbers indicating better filtration.

MERV Ratings Explained

Here’s a breakdown of MERV ratings and what they mean for your home:

  • MERV 1-4: Basic filtration, captures large particles like dust and pollen
  • MERV 5-8: Medium filtration, traps smaller particles like mold spores
  • MERV 9-12: Superior filtration, catches fine particles like auto emissions
  • MERV 13-16: Hospital-grade filtration, removes bacteria and smoke
  • MERV 17-20: HEPA filtration, used in cleanrooms and surgical settings

Choosing the Right MERV Rating

While it might seem logical to opt for the highest MERV rating possible, this isn’t always the best choice. Higher-rated filters can restrict airflow, potentially causing your system to work harder and less efficiently. For most residential HVAC systems, a MERV rating between 8 and 13 provides an excellent balance of filtration and efficiency.
