Bullfrog Spa Simplicity Filter

These filters are specifically engineered for Bullfrog Spa Swim Series, M Series, and A Series models from 2023 and newer. Always check your spa's manual or current filter housing to confirm the model year and series before purchasing.

For optimal water clarity and to prevent strain on your spa's pump, we recommend replacing these filters every 3 to 4 months. If you use your spa frequently or notice a decrease in water flow, you may need to replace them sooner.

While you can rinse the pleated media with a garden hose to remove surface debris, these cartridges are designed for replacement rather than long-term cleaning. Over time, oils and fine particles become embedded in the polyester, which reduces filtration efficiency.

Yes, this box contains four filters. If you follow the standard replacement schedule of every three months, this pack provides exactly one year of filtration for your spa.

Installation is straightforward: simply turn off your spa's power, remove the old cartridge, and slide the new one into the filter housing. Ensure it is seated firmly to prevent water from bypassing the filter media, which would allow debris to circulate back into your spa.
