LIQUID JUST GOT SMARTER

Introducing FreshWater® IQ, the most intelligent salt water system on the planet.

FreshWater IQ is a smart, in-line water care system that automatically tests your spa water and displays clear instructions to simplify water maintenance. Now you can tell at a glance when chemicals are needed, taking the guesswork out of keeping your spa water balanced and ready to enjoy.

Made for Hot Spring Spas, FreshWater IQ is available on Highlife® Collection and Limelight® Collection spas.

How It Works

FreshWater IQ combines two innovative technologies, the FreshWater Salt System and our Smart Monitoring System.

The Salt System uses a titanium cartridge to automatically generate chlorine from salt to keep your spa water fresh, clear, and natural-feeling.
 

The Smart Monitoring System regularly tests your water 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

Better Water. Fewer Additives.

FreshWater IQ uses the FreshWater Salt System to generate the perfect amount of chlorine. 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. The FreshWater Salt System works with our proprietary 100% no-bypass filtration system to help you experience the best spa water possible.
Hot Spring's hot tub control panel featuring a digital display showcasing hourly saltwater analysis results. The interface provides data on chlorine levels, pH balance, and salt sanitizer concentration, along with smart sensor and cartridge metrics.
