How to Locate NSF Certification Information?
Step 1: Visit pld.iapmo.org.
Step 2: Choose the search category as 'Listed Model / Additional Company'.
Step 3: Input "PLFPRB50-IN-M" into the 'brand name/model' field.
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:
1. Gauge the cartridge's external diameter, ensuring accuracy to within +/- 1/16 inch.
2. Measure the cartridge's length from one end cap to the other, excluding any protruding handles or extensions, to within +/- 1/16 inch.
3. 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").
4. Note down the filter's manufacturer and model number where the new cartridge will be placed.
5. Check if there's a central core (like a PVC pipe) present.

High Chlorine Resistance End Cap

Extended Lifespan, Greater Savings
With the right care and maintenance, the POOLPURE filter is designed for repeated use. This not only prolongs the filter's life but also offers significant cost savings over time.

I took a chance in buying these filters because they say they are 13x5 inch size. But in actuality they were slightly taller by about a 5/16 inch. I have a Dr wellness x10 spa but even though the new filter was slightly taller than my original filter they still fit perfect and work great. Significantly less cost than the original filters I was getting. Would definitely recommend.

This replacement filter was for my spa. It was a perfect fit and keeps my water crystal clear. This will be my go to replacement filter from now on. It was half the price of of the pool store and it's quality and build is the same if not better.

Sturdy, solid build and will likely stand up to the abuse but will update in 6 months.

We had a hard time finding filters to fit our hot tub. These were perfect. The price is good too. Our water has never been cleaner. These were easy to install as well.

No complaints! For a few additional dollars the filter quality and functionality are noticeable. Only time of service will provide longevity.
