Why is MERV important?
Studies show that central air filtration is the best way to improve indoor air quality. MERV ratings determine how effective that filtration is. Good indoor air quality reduces the symptoms of asthma and allergies, especially in children. For more information on indoor air quality
What Is Merv ?
Mechanical air filters are the most common type of home air filters used in residential HVAC systems.
These filters use synthetic fibers to trap small particles, debris, and dust, among other things — preventing those things from circulating in the air and getting into our lungs.
The effectiveness of a mechanical air filter is measured in MERV ratings (Minimum Efficiency Reporting Value). Generally speaking, the cheaper the filter is, the lower the MERV number is. In other words, you get what you pay for. Air filters with lower MERV ratings need to be replaced more frequently.
MERV Rating System
How The Ratings Work
MERV (Minimum Efficiency Reporting Value) is the industry-standard ratings system used to measure the effectiveness of air conditioner filters. Ratings for residential and commercial AC filters typically fall between MERV 5 and MERV 12. Filters with higher MERV ratings remove more particles and allergens than lower-rated filters.

What MERV Rating is Right for Me?
The American Lung Association recommends using at least a MERV 8 filter. People who suffer from asthma and allergies should use a higher quality MERV filter, at least MERV 11.
