What Are MERV Ratings and Why Do They Matter?
At Wighton’s, we frequently get questions about air filtration systems and their effectiveness. Since 1953, we’ve been helping Central Coast residents understand the importance of proper air filtration, and one of the most crucial aspects is understanding MERV ratings.
MERV (Minimum Efficiency Reporting Value) ratings range from 1 to 20 and indicate how effectively an air filter can trap airborne particles. The higher the MERV rating, the more efficient the filter is at capturing smaller particles from your indoor air.
Common MERV Ratings Explained:
- MERV 1-4: Basic filtration for large particles
- MERV 5-8: Good for residential use, captures dust and pollen
- MERV 9-12: Excellent for homes, traps smaller particles
- MERV 13-16: Superior filtration, medical-grade
- MERV 17-20: Used in specialized clean rooms and hospitals
For most homes in San Luis Obispo County and the surrounding areas we serve, we typically recommend filters with MERV ratings between 8 and 13. This range provides excellent air quality without putting unnecessary strain on your HVAC system.
Maintaining Your Air Filtration System
To ensure optimal performance of your air filtration system, regular maintenance is crucial. At Wighton’s, we recommend:
1. Checking filters monthly
2. Replacing filters every 3-6 months
3. Professional system inspections annually
4. Keeping vents clean and unobstructed
