WRAS Approved

The Kube 1 Water Softener is the best introductory water softener on the market that’s great value, easy to install and economical to run. The non-electric design is powered by the natural flow of the water and provides beautiful soft water for you and your home so you can banish limescale forever. The compact design means it fits neatly under your kitchen sink and is suitable for households with up to 2 bathrooms. The only maintenance your softener requires is to replace the tablet salt.

With soft water you’ll save time cleaning and discover shiny taps, free-flowing showers and clear shower screens. Soft water running through your home will also increase the life of your appliances such as your dishwasher, washing machine and boiler and you’ll save money too. You can ditch the spray-on limescale removers, use less detergents, bath foams and toiletries. 
Operating using only the power of moving water, this Kube 1 Water Softener offers reliability and easier installation. It requires no power cables or electronic components, which means it won't corrode over time and you'll have no electricity costs and includes a 15mm fitting kit making installation easy.
