PRB50-IN filter

We also offer the equivalent Claralys filter, manufactured in France with a honeycomb-textured fabric that does not fray over time and captures more impurities than generic filters, ensuring optimal filtration.

Dimensions
Diameter: 125 mm (5")
Length: 338 mm (13 1/4")
Top: 54 mm hole
Bottom: 54 mm hole
Filtration surface area: 50 square feet (212 pleats)

This filter has exactly the same dimensions as the C-4326/PRB25, but has twice as many pleats and therefore twice the surface area. The two models are completely interchangeable, but if you are in any doubt about which filter to use, we suggest that you stick with the version that was originally supplied with your spa.

This filter is also available in Microban
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.
