Box of 9 PRB50-IN Proline filters

This is a box of six Proline filters. We also sell these filters individually and in Claralys boxes of 6.

Dimensions
Diameter: 125 mm
Length: 338 mm
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.
