Max CFM based on 600 FPM
# CFM -- Cubic Feet Per Minute airflow. Filter required for each return--air inlet.
Airflow perfomance includes 1” washable (600 FPM max) filter media.
Disposable filters are typically rated at 300 FPM and only allow half of the airflow when compared to 600 FPM filters.
Example 20 x 25 @600 FPM = 2000 CFM, @300 PFM = 1000 CFM.
