What Is A MERV Rating And Why Does It Matter?Updated 2 months ago
Air filters' ability to capture airborne particles, and their effectiveness, are evaluated and measured byMERV ratings (Minimum Efficiency Rating Value) on a scale from 1 to 16. MERV filters with higher ratings trap finer particles, but might restrict air flow and affect HVAC performance. Your HVAC system will function better if you choose an air filter in the appropriate size with a MERV rating that balances air flow and filtration.
