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.

I needed a replacement filter for my hot tub as the regular brand was out of stock. This two pack of filters was a good price. The first one was installed last week, fit perfectly & is doing its filter thing.

I am only giving 4/5 stars because these filters cannot actually be screwed into my filter slot though it is the correct thread type and filter size... So it's a close but no cigar situation for us personally. I'm starting to see all these spa makers basically have made tiny little changes to whatever they can to keep you buying their rip off crazy priced brand name filters specific to their spa brand. Well my spa brand can suck it because these are still able to be pressed into place instead of screwed in and are working just fine for the free hot tub my kind friend gifted myself and my spouse with for our chronic arthritis and we couldn't be more pleased with them. I will keep on purchasing as long as the price stays affordable and they keep fitting! I do thank the manufacturer for actually having a website to check sizing/thread types available so that I could even find and figure out how to replace said crazy priced original brand spa filter so my pocketbook and sore back and joints thank you kindly!

This filter worked on my Free Flow spa perfectly at half the cost of other filters from Free Flow spas.

Great replacement filter, my spa tub is discontinued and replacement filters difficult to find, this fits perfectly and is good quality, expensive so hopefully it lives up to the advertising and lasts longer than ordinary filters
