To determine the size of your Pentair pool filter, check the label or nameplate on the filter tank, which usually lists the model number and filtration area (in square feet) or flow rate (in gallons per minute). If the label is missing or unclear, you can also look up the model number in your owner’s manual or on the Pentair website for specific sizing information.
