Supporting Statistics: The Impact of MERV Ratings on Air Quality and Efficiency
Health Benefits of Improved Air Quality:
Indoor air can be up to 5 times more polluted than outdoor air (EPA).
Poor air quality contributes to respiratory problems, allergies, and asthma.
Higher MERV filters (MERV 11 or higher) capture smaller particles, improving health.
In my experience, upgrading filters often leads to noticeable symptom reduction for those with respiratory issues.
