About This Item
⚠️ IMPORTANT: VERIFY YOUR FILTER TYPE BEFORE ORDERING
Freeflow Spas used two different filter styles across model years. This cartridge features a 1-1/2" threaded (MPT) bottom fitting that screws onto a standpipe inside the filter housing. Newer models (approx. 2016 and later) use a non-threaded drop-in cartridge — if your current filter does not have a threaded base, this is NOT the correct replacement. Inspect your existing filter before ordering.

Pro Tip: Before ordering, remove your existing filter and inspect the bottom. If it has a threaded fitting (screws onto a standpipe), the 5CH-45 is your match. If it simply drops into the housing with no threads, check the 4CH-949 instead. When in doubt, match the OEM part number printed on your existing filter's end cap or housing label.
