Filter Ratings Explained

What is APR?

APR, short for Accumulair Performance Rating, is a scale developed by Accumulair Filters to indicate filter efficiency. Higher APR ratings signify better performance in capturing small airborne particles. It's important to note that APR is specific to Accumulair filters and is an internal rating system.


What is MERV?

MERV, or Minimum Efficiency Reporting Value, measures how effectively an air filter removes dust particles and airborne contaminants. A higher MERV rating indicates greater efficiency in capturing these particles, resulting in cleaner air passing through the filter.
