How It Works.
FreshWater IQ combines two innovative technologies, the FreshWater Salt System and our Smart Monitoring System.
The Salt System uses a disposable titanium cartridge to generate chlorine from salt to keep spa water fresh, clear, and natural feeling.
The Smart Monitoring System regularly tests your water every hour and indicates when adjustments are needed for pH, chlorine and salt levels, helping you maintain clean, balanced spa water.
SMARTER
We Put the IQ in Liquid.
Our patented smart monitoring technology, found only in the FreshWater IQ System, automatically tests your water every hour, offering more accuracy than test strips. It displays clear recommendations when adjustments are needed. You’ll enjoy peace of mind knowing your spa is helping you keep your water fresh and ready for your next soak.
CLEANER
Water That Makes You Go Ahhhh.
FreshWater IQ uses the FreshWater Salt System to generate the perfect amount of chlorine from salt. With fewer chemicals required, 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.
