The Science Behind Clean Indoor Air
When it comes to maintaining optimal indoor air quality, understanding MERV ratings is crucial for every homeowner. At Coastal Comfort Inc, we regularly educate our customers about the importance of proper filtration in their HVAC systems.
MERV (Minimum Efficiency Reporting Value) ratings range from 1 to 20, with higher numbers indicating better filtration capabilities. Here’s what you need to know:
MERV Rating Breakdown:
- 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 commercial grade
- MERV 17-20: HEPA grade filtration
Most residential HVAC systems work best with filters rated MERV 8-13. Going too high can restrict airflow and strain your system, while too low won’t provide adequate filtration. The key is finding the right balance for your specific system.
Filter Maintenance Tips:
- Check filters monthly
- Replace every 60-90 days
- Consider more frequent changes during high-use seasons
- Monitor system performance after filter changes
Remember that proper filtration not only improves air quality but also helps maintain system efficiency and longevity. Regular maintenance and appropriate filter selection are essential components of a well-functioning HVAC system.
