PWL35P4-M filter

Dimensions
Diameter: 145 mm
Length: 173 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 is a Pleatco Microban filter. Microban inhibits the growth of bacteria on the surface of your hot tub filter. Microban filters stay clean longer and last longer than conventional spa filters.

This filter is fully interchangeable with the PWL25P4-M. The only difference is the number of folds in the filtration fabric, and therefore the filtration surface area. The PWL25 has a surface area of 25 square feet, and the PWL35 has a surface area of 35 square feet.
