The ProAqua PA-4935 hot tub filter has a closed top with a handle and course female threads on the bottom. It is a compatible replacement for the Pleatco PWW35L, Unicel 4CH-935 and Filbur FC-0170 hot tub filters. This ProAqua hot tub filter cartridge is built to last, with durable materials that can withstand regular use and exposure to balanced hot tub chemicals. To ensure a perfect fit, be sure to compare the dimensions of this filter cartridge to your old one before purchasing.



  • ProAqua P/N: PA4935
  • Diameter: 4-15/16"
  • Length: 9-1/4" (with handle) 8-1/4" without handle
  • Top Hole: Closed with Handle
  • Bottom Hole: 1-1/2" FEMALE SAE Threaded (threads measure slightly larger inside diameter)
  • Brand: Pro Aqua by Magnum Filters


Please note:

Unicel and Pleatco brands of this filter use threads on the bottom that are inside a raised hole. Magnum Filters have developed a new design for the bottom made with stronger PVC plastic, which leads to a more rigid filter and requires less threads to seat properly. The new PVC plastic ends are designed to last longer under the harsh conditions of spa water.
