Bullfrog Hot Tub Replacement Filters
Bullfrog Spas (also Watkins Wellness, also based in Utah) is best known for the JetPak system, where you can swap jet panels around the tub. The filtration is more conventional: most Bullfrog A-series and R-series tubs run a single Pleatco cartridge in a standard housing.
The 5 Bullfrog models below are mostly 2013-and-later. If yours is older or you've installed an aftermarket JetPak that came with its own filtration, double-check against your existing cartridge.

Quick tip: the fastest way to confirm the right cartridge is to pull yours and read the part number off the end cap. The owner's manual is the backup if the printing has worn off.
