good

• 【APPLICABLE】 Compatible with Hot Springs Highlife Series, Hot Spring Limelight Series, Caldera Utopia Series and Caldera Paradise Series produced in 2019 or later.
• 【ECONOMICAL CHOICE FOR WATER QUALITY IMPROVEMENT】Salt system cartridges combined with the salt system of the hot tub can effectively reduce water hardness, reduce the formation of scale and sediment, and keep the bathtub water clear and transparent. Each salt system filter has a service life of up to 4 months and does not need to be replaced frequently.
• 【REDUCE EQUIPMENT MAINTENANCE TIME】Reducing the formation of scale helps to extend the life of the bathtub and related pipes, pumps and other equipment. Let you spend more time enjoying the spa instead of cleaning and maintaining the spa equipment.
• 【MORE AFFORDABLE SKIN CARE】Softened water is gentler on the skin, reduces irritation and dryness, and helps to maintain the moisture and radiance of the skin. Unlike fast-consuming skin care products, three salt system cartridges can bring you a year of skin care.
• 【EASY TO INSTALL】You can refer to the video or picture installation steps in our product details, and the installation can be completed in a few minutes without tools.
