What Are MERV Ratings and Why Should You Care?
If you’re like most homeowners in the Orlando area, you probably don’t think much about your air filter until it’s time to change it for better air quality. However, understanding MERV ratings can make a significant difference in your home’s air quality and your HVAC system’s efficiency.
MERV (Minimum Efficiency Reporting Value) ratings range from 1 to 20, with higher numbers indicating better filtration. Here’s what you need to know:
MERV Rating Categories:
- MERV 1-4: Basic filtration for larger particles
- MERV 5-8: Better residential filtration
- MERV 9-12: Superior residential and basic commercial
- MERV 13-16: Hospital and general surgery level
- MERV 17-20: Clean room and surgical level
For most homes in Winter Park and surrounding areas, a filter with a MERV rating between 8 and 13 provides excellent air quality without straining your system. Higher isn’t always better – using a filter with too high a MERV rating can restrict airflow and make your system work harder.
Regular maintenance of your filtration system is crucial for maintaining optimal indoor air quality. When choosing a filter, consider factors like:
- Local pollen counts
- Presence of pets
- Family members with allergies or respiratory issues
- Age and capacity of your HVAC system
Remember to check and replace your filters regularly, especially during peak allergy seasons in Central Florida. Your HVAC system will thank you with improved performance and longer life.
