If you love your hot tub, the last thing you want is to spend your time playing scientist, constantly testing water and worrying about balance. In fact, the number one question we get asked from new spa owners is how to look after the water. That’s why HotSpring created the FreshWater System, which includes two separate but complementary technologies: the FreshWater Salt System and FreshWater IQ.

The FreshWater Salt System is the foundation. It uses a small amount of salt to generate natural chlorine, keeping your spa water clean, clear, and soft. Chlorine is produced automatically, so you spend less time maintaining your spa. The water feels gentle and smooth on the skin, with no harsh smells, and with proper care it can last up to 12 months before a full drain and refill. Cartridge changes are quick and easy, usually needed around every four months.

FreshWater IQ is the intelligent companion to the Salt System. It constantly monitors your water, checking chlorine, pH, and salt levels, and provides clear guidance via your spa’s control panel or app. FreshWater IQ only works alongside the Salt System, using its chlorine production to maintain perfectly balanced water. Together, they ensure your spa water is always safe, clean, and ready to use, without you having to lift a finger.

Most other systems still rely on test strips, bottles, and guesswork. With FreshWater, the process is automated, so there’s no measuring, mixing, or playing scientist. Spa ownership should feel easy and enjoyable, not intimidating. The technology quietly does the science behind the scenes so you don’t have to.

The water is always continuously clean, soft, and inviting. Low salt levels mean it feels luxurious and soothing on your skin without any harshness. It is also more sustainable, reducing water waste and the need for additives.

The FreshWater Salt System is available as an option on HotSpot and Limelight spas and comes as standard on Highlife models. FreshWater IQ requires the Salt System to operate and is available as an upgrade on select models.
