Understanding MERV Ratings: Your Guide to Better Indoor Air Quality
2 min readThe Hidden Impact of Air Filtration Systems
When it comes to maintaining your home’s indoor air quality, understanding MERV ratings is crucial. At JTR Energy, we frequently encounter customers who are unsure about which filtration system best suits their needs.
What is a MERV Rating?
MERV (Minimum Efficiency Reporting Value) ranges from 1 to 20 and indicates how effectively an air filter captures particles. The higher the MERV rating, the smaller the particles it can trap.
Common MERV ratings and their applications:
- MERV 1-4: Basic filtration for residential systems
- MERV 5-8: Better residential filtration, capturing mold spores
- MERV 9-12: Superior residential filtration, ideal for allergy sufferers
- MERV 13-16: Hospital general surgery level
- MERV 17-20: Clean room and surgical facilities
Choosing the Right Filter
Most residential HVAC systems work best with filters rated MERV 8-13. Higher ratings can restrict airflow and strain your system unnecessarily. When selecting a filter, consider:
- Your HVAC system’s specifications
- Family members with respiratory issues
- Local air quality conditions
- Pet ownership
Regular maintenance and proper filter selection ensure optimal system performance and healthier indoor air. Remember, the most expensive filter isn’t always the best choice for your specific situation.
Professional Recommendations
For most homes with standard HVAC systems, we recommend starting with a MERV 8 filter and upgrading based on specific needs. This provides excellent filtration while maintaining proper airflow through your system.
