How to Determine the Right Replacement Cartridge for Your Pool or Spa?
Already have the part number? Simply input the filter cartridge's part number or its replacement number into the search bar on our product page to verify compatibility.
Unsure of the part number? Selecting the appropriate cartridge can be achieved by assessing your current one. Follow these steps:
- Gauge the cartridge's external diameter, ensuring accuracy to within +/- 1/16 inch.
- Measure the cartridge's length from one end cap to the other, excluding any protruding handles or extensions, to within +/- 1/16 inch.
- Determine the top and bottom type. If they're open, measure the inner diameter of the opening to within +/- 1/16 inch. For closed end caps, jot down distinct features (e.g., "Handle", "Cone").
- Note down the filter's manufacturer and model number where the new cartridge will be placed.
- Check if there's a central core (like a PVC pipe) present.
Specifications of PLF4CH-935:
- Length: 8 1/2"
- Outside Diameter: 5”
- Top: Handle
- Bottom: 2" Female SAE Threaded

I own a Master Spa hot tub and my OEM filter model is x268548. The OEM filter has some type of orange charcoal insert. This one doesn't, but I had no issues with the fit and it does the job as a filter should. In my opinion, that charcoal insert was a feeble attempt by the manufacturer to try and steer customers towards buying filters from only them. However I know charcoal is for filtering drinking water, not spa water! They actually told me I should change that charcoal insert every month and it costs $50 a pop! Yeah no thanks. Anyway I never changed it in 3 years. I finally got around to changing the original filter (which I had simply been cleaning with each water change) to this one. This one does the job, water is clean, and it's much less expensive! Win!

I have had my hot tub for 5 yrs now , I always purchased the manufacturer brand filter . I decided to try to save some $ and try something different. So very glad I did ! This filter is by far the best filter I ever used, it has been a month now my water is crystal clear, the best it's ever been !! truly !! Don't hesitate to buy one the onl suggestion is to measure your old one. This filter rinses off so easy and clean !!! I will never buy from the manufacturer again!

I got these for my 4 Winds "Cyclone Series" hot tub. The original filter was 4CH-935. I switched over to the Pleatco PWW35L after they stopped manufacturing my original filter. I am now trying these ones. As you will see, they are slightly skinnier and a tad taller but do fit into the filter of my hot tub. Not sure quite yet on their longevity but they do replace either model filter listed herein. Packaged well in a box and both individual filters are shrink wrapped. The two (2) pack is about the same price I used to pay for just the one (1) filter. This will also allow me to soak/clean one while still having a filter in place. So you got that going for you too!

We will be using the PoolPure PLF4CH-935 for our MasterSpa filtering needs from now on! No installation issues with sizing, quality or filtration. I will update when it's time to change it out to see how it compares with the Pleatco factory filter.

This filter was a little taller than my original filter. It fit in the compartment and seems to be doing a great job.

Very happy to have found this filter fits Clarity Spas and is a great replacement for the PMA-R3 X268548.This doesn't have a spot for the Eco Pur Charge but if you just want to change the filter this is great, and at a much lower price. The unit is slightly taller than the original but still fits.I will update this review after a month or two to add info about performance,
