FreshWater IQ is an in-line self-monitoring salt system that tells you what it needs to maintain clean, natural-feeling water, with less time and effort. Because we believe your hot tub should take care of you, not the other way around.

Made for Hot Spring Spas, FreshWater IQ is available on 2024 Highlife® Collection and Limelight® Collection Spas.

How It Works

The Salt System automatically generates chlorine from salt to keep your spa water feeling naturally fresh and ready to enjoy.

The Smart Monitoring System automatically tests your water every hour and provides clear instructions when adjustments are needed for clean water.

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.
