MERV 8, MERV 11, and MERV 13 are common air filter efficiency ratings used in HVAC systems. MERV (Minimum Efficiency Reporting Value) gauges the filter's ability to capture and eliminate airborne particles.

A MERV 8 filter targets particles larger than 3.0 micrometers, like dust, pollen, and mold spores, capturing 70-85% of them.

A MERV 11 filter focuses on particles larger than 1.0 micrometers, including finer dust, pet dander, and some bacteria, with an efficiency of 85-90%.

A MERV 13 filter aims at particles larger than 0.3 micrometers, like bacteria and some viruses, removing 90-95% of them.

Each MERV rating offers distinct filtration capabilities for tailored air quality enhancement.
