FreshWater IQ

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.

How It Works:
Salt System + Smart Monitoring System

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.

Put the IQ in Liquid

The 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 need. 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 the proprietary no-bypass filtration system, you are soaking in the cleanest water possible, each and every time.

*Many factors affect the life of spa water, such as bather load and water chemistry. When these factors are accounted for and the spa is properly maintained, the FreshWater Salt System will keep water clean and clear for up to a full year.
