Understanding MERV Ratings
MERV (Minimum Efficiency Reporting Value) is the industry standard used to measure an air filter's ability to capture airborne particles. As MERV ratings increase, filters become more effective at capturing smaller contaminants that can affect indoor air quality.
MERV 6 filters provide basic protection against lint and large dust particles. MERV 8 filters are the most common choice for residential HVAC systems and help capture mold spores and dust mites. MERV 11 filters offer increased protection against pollen and pet dander, making them a popular option for households with pets or allergy concerns. MERV 13 filters provide the highest level of residential filtration by capturing finer airborne particles such as smoke, smog, and bacteria carriers.
Before upgrading to a higher MERV rating, always verify that your HVAC system is designed to accommodate increased filtration efficiency while maintaining proper airflow.
Frequently Asked Questions
What is the difference between nominal and actual filter size?
Nominal size is the rounded filter size used for identification and ordering. The actual dimensions of this filter are approximately 19.75" x 24.75" x 0.75".
Is a MERV 8 filter good for allergies?
