How to measure a cartridge
Measure the outside diameter of the filter cartridge in inches.
Measure the length of the filter cartridge from end cap to end cap.
Do not include things like handles or threaded bottoms in the
measurement.
Identify the end cap configuration. Is it threaded with a handle, or
open on both sides? Look at the pictures below to help you better
identify the end cap. If it is open measure the inner diameter of the
whole.
To better identify the cartridge, count the number of pleats. This
allows us to know the square footage of the cartridge in question.
