The Impact of Filter Ratings on Your Home’s Air
When it comes to maintaining optimal indoor air quality, one of the most crucial yet often overlooked components is your HVAC system’s air filter rating. At Farley & Hysaw, we frequently discuss the importance of proper air filtration systems with our customers.
What is a MERV Rating?
MERV (Minimum Efficiency Reporting Value) ratings range from 1 to 16 for residential use, with higher numbers indicating better filtration. Here’s what you need to know:
- MERV 1-4: Basic filtration, catches large particles
- MERV 5-8: Mid-range filtration, good for residential use
- MERV 9-12: Superior residential filtration
- MERV 13-16: Hospital-grade filtration
Choosing the Right MERV Rating
Most residential HVAC systems work best with filters rated MERV 8-11. Higher ratings aren’t always better – they can restrict airflow and strain your system if not properly matched to your equipment’s specifications.
Maintenance Considerations
Remember these key points:
- Check filters monthly
- Replace every 3-6 months
- Consider humidity levels when setting replacement schedules
- Monitor system performance after filter changes
Understanding MERV ratings helps ensure your heating and cooling system operates efficiently while maintaining healthy indoor air quality. Regular maintenance and proper filter selection are essential components of a well-functioning HVAC system.
Remember to consult with qualified professionals when making decisions about your home’s air filtration needs to ensure optimal system performance and longevity.
