We Put the IQ in Liquid

Our patented smart monitoring technology, found only in the FreshWater IQ System, automatically tests your water every hour and is more accurate and dependable than test strips. It then provides clear recommendations when adjustments are needed. Relax, knowing your spa will tell you how to keep your water feeling naturally fresh and ready to enjoy!

Purity at the Push of a Button

FreshWater IQ uses the FreshWater Salt System to generate the perfect amount of chlorine. With fewer chemicals, water feels softer and gentler on eyes and skin, and can stay clean and fresh for up to a full year*, conserving water and saving money. Paired with our proprietary no-bypass filtration system, you are soaking in the cleanest water possible, each and every time.
