【Economical Choice for Water Quality Improvement】Keptwell Salt system cartridges, when used in conjunction with the hot tub's HP ring system, effectively reduce water hardness, minimize scale and sediment buildup, and maintain crystal-clear water. With fewer chemicals needed, the water feels softer and is gentler on the eyes and skin, remaining clean and fresh for up to a full year. This approach not only conserves water but also saves money.

【APPLICABLE】Compatible with Hot Sp Highlife Series, Hot Spring Limelight Series, Calde FR Utopia Series, and Calde FR Paradise Series manufactured in 2019 or later.

【More Affordable Skin Care】Softened water is gentler on the skin, reducing irritation and dryness while helping to maintain moisture and radiance.
