Understanding MERV Ratings: Your Guide to Better Indoor Air Quality

When it comes to maintaining your indoor air quality, few components are as crucial as your HVAC system’s air filter. At Oakmont Mechanical, we often field questions about MERV ratings and their significance in maintaining optimal air filtration.

What is a MERV Rating?

MERV (Minimum Efficiency Reporting Value) represents the standardized measurement system for air filter effectiveness. The scale runs from 1 to 20, with higher numbers indicating better filtration of smaller particles.

Common MERV Ratings Explained:

  • MERV 1-4: Basic filtration for large particles
  • MERV 5-8: Medium filtration, good for residential use
  • MERV 9-12: Superior residential filtration
  • MERV 13-16: Hospital and general surgery level
  • MERV 17-20: Clean room and surgical operating room grade

Choosing the Right MERV Rating

Most residential HVAC systems work best with filters rated between MERV 8 and MERV 13. Going too high can restrict airflow and strain your system, while too low may not provide adequate filtration.

Important Considerations:

  • System compatibility
  • Local air quality
  • Presence of allergies or respiratory conditions
  • Energy efficiency goals

Regular maintenance of your filtration system ensures optimal performance and longevity of your HVAC equipment. Remember to check and replace filters according to manufacturer recommendations, typically every 3-6 months depending on usage and environmental conditions.
