Freeflow Pleated Filter

The Freeflow Pleated Filter (PFF50P4 / PFF42TCP4) is a replacement pleated cartridge filter for Freeflow brand spas. If your spa is a Freeflow (not an Arctic Spa) and the original filter cartridge has reached end of life, this is the direct OEM-spec replacement.

When to replace your spa filter: Pleated filter cartridges typically last 12-18 months of normal use before the pleats break down, water flow drops noticeably, and even thorough cleaning doesn't restore performance. Symptoms of a tired filter: weaker jet pressure than you remember, persistent cloudy water that won't clear despite balanced chemistry, or visibly grey/permanently dingy pleats that don't come clean with a hose-down.

Will this fit my spa? Yes, on Freeflow brand spas using the PFF50P4 / PFF42TCP4 filter spec. If you have an Arctic Spa, you need a different filter — see the Pleated Filter 50' Thread-In family or the Silver Sentinel Thread-In disposables. Bring your old filter to one of our three Ontario showrooms if you're not sure of fitment.

Care: Rinse the pleats top to bottom with a garden hose every 2-4 weeks. Once a quarter, soak overnight in a filter-cleaning solution like Aqua Finesse Filter Cleaner, then rinse thoroughly. Never use a pressure washer; it shreds the pleats.
