The SPECTRUM S1 is a whole-house softener designed to protect your home from the damaging effects of hard water, while improving the feel and quality of your water supply. The S1 works throughout your home to prevent limescale build-up in sinks, taps, showers and plumbing, helping your appliances last longer and run more efficiently, helping to lower household bills by up to 12%. Soft water in your home is kinder to your skin and hair, keeps clothes brighter for longer, and leaves glassware and kitchenware sparking clean. Intuitive touch controls make this system easy to operate, with the option to choose between volumetric or timed regeneration, while a built-in blend valve allows you to set the exact softness level you prefer. With its integrated brine tank and smart design, the SPECTRUM S1 offers a reliable, space-saving solution to hard water for both residential and light commercial use. The softener comes complete with an installation kit. For safety and performance, professional installation by a plumber is required.
