Keep your water sparkling clear with genuine Bullfrog replacement filters

These filters only fit Bullfrog STIL models.

• To get clean water with minimal effort, Bullfrog also recommends the official Frog @Ease Mineral Sanitizing System.
• Some Bullfrog hot tubs ship from the factory with white Wellspring filters. We don’t know why, but all replacement Wellspring filters are blue. Blue or white, these are genuine Bullfrog factory parts.
• We are factory-authorized Bullfrog dealers, so we take pride in our knowledge of Bullfrog’s catalog. If you’d like to talk to someone before you place your order, just give us a call.
• Part # 10-00281 is a genuine Bullfrog part, so you know it was designed with your STIL spa in mind.
• Modern filtration media trap dirt, pollen, and microbes while allowing clear water to pass through.
• Use less chlorine with a fresh filter.
