Water Care That Works For You
Three Innovative Technologies.
One Seamless Experience.
FreshWater IQ combines three game-changing innovations, FreshWater Salt, Smart Monitoring, and new Dosing Systems into one integrated solution.
NEW! Dosing System
Our latest innovation, this delivers accurate
doses of pH Up, pH Down, and Phosphate
Remover with a simple tap, using refillable
cartridges tucked discreetly under the spa’s
filter lid.
Smart Monitoring System
The brain behind the system, this checks pH,
chlorine, and salt levels every hour, and
displays updates and actionable
recommendations on your screen.
Salt System
The foundation of the system, this
generates chlorine from salt using a
replaceable titanium cartridge to keep spa
water fresh, clear, and natural-feeling.
- Our new Hot Spring® Spas app lets you manage, balance, and monitor your spa water anytime, from anywhere. With just a touch, you’ll enjoy added convenience and peace of mind, whether you’re at home or on the go.
FreshWater IQ (Salt System with Smart Monitoring and Dosing) is available on Highlife® and Limelight® Collection spas only. The FreshWater Salt System is available on Hot Spot® Collection spas. FreshWater IQ is not available on Freeflow® Collection spas. Please refer to the compatibility chart below for details.
