Filter testers determine the efficiency of an air filter by measuring the reduction in particle concentration within an air stream as it passes through the filter. This is typically done using a controlled environment where particles of a certain size range are introduced into the airflow. The initial concentration of particles is measured, and the air is then passed through the filter. Subsequent particle concentration measurements are taken on the filtered side. By comparing the before and after concentrations, the efficiency of the filter in capturing particles is calculated.
