Replacement cartridge for the Premium AOP System by Clear Comfort® used with compatible Bullfrog Spas hot tubs and swim spas. The system operates automatically while the spa filters, using advanced oxidation to help break down contaminants and support clear, soft-feeling water. Bullfrog lists cartridge life at approximately 1–3 years, depending on use. Confirm your spa’s AOP system and cartridge compatibility before ordering.
