Shop for Water Dispensers & Filters at The Home Depot. ScaleBlaster is an innovative, computerized water conditioning system that solves hard water problems without the need of chemicals or salt. The product requires no maintenance and is simple to install, with no plumbing required. ScaleBlaster removes and prevents lime-scale deposits in household pipes. It will protect and prolong the life of water heaters, dishwashers and washing machines. Lime-scale deposits on shower heads, sinks and faucets will easily wipe off or disappear. Soap lathers up more, skin feels smother and hair becomes more manageable. Enjoy healthier and better tasting water as well as brighter, whiter and longer lasting clothes, towels and sheets. Water softeners require salt, waste lots of water and discharge chlorides into the environment. They also require ongoing costly maintenance. For people on salt restricted diets, ScaleBlaster is a healthy alternative. ScaleBlaster is also ideal for tankless water heaters. First appearing in 1995, ScaleBlaster is now successful worldwide.
