This all-new FROG® @ease® Simplicity cartridge system is designed specifically for Bullfrog Spas models with the Simplicity Filtration System (flat rectangular filter). This includes all M Series models and 2023 and later A Series models. The Regular quantity cartridges included are recommended for up to 1 month of use in models in 5, 6, & 7-sized spas.
FROG @ease systems offer a self-regulating water care experience that is easier than ever.* SmartChlor® technology uses up to 75% less chlorine, maintains chlorine at significantly lower levels, and reduces the frequent need for hot tub maintenance.

The package includes 3 SmartChlor replacement cartridges in Standard quantity.

Fits in spas with the updated Simplicity Filter Housing (Part # 10-04669). If your spa was manufactured before 2024 or does not have this part, the updated Simplicity Filter Housing may be ordered here and is retrofittable in any spa with the Simplicity Filtration System.
