Box of 6 Claralys CWL25P4 filters

This is a box of 6 filter cartridges !
We also sell this filter individually.

Dimensions
Diameter: 143 mm
Length: 174 mm
Top: Handle
Bottom: 1.5" MPT thread (46-47 mm outside diameter)

Measure the length of the filter excluding the handle and the threaded pipe.

Filters from different manufacturers all have slightly different handles. The most common are a cone-shaped handle (Unicel) and a D-shaped handle (Pleatco), but they are all compatible with one another. If the length and diameter match, then this is the correct filter for your spa.

This filter is fully interchangeable with the PWL35P4-M. The only difference is the number of folds in the filtration fabric, and therefore the filtration surface area. The CWL25P4 filter has a surface area of 25 square feet, and the PWL35P4-M has a surface area of 35 square feet. If only there was a way to figure out the surface area directly from the part number, it would save us a lot of time looking this stuff up...
