iSpring Whole House Electronic Descaler Water Conditioner (ED2000)

The iSpring ED2000 Whole House Electronic Descaler Water Conditioner is an innovative, computerized water conditioning system that solves hard water problems without the need for chemicals, salt, or filter cartridges. This makes it a healthy and economic alternative to a traditional Water Softener, and great for those on salt-restricted diets. It will prevent lime scale deposits in water pipes, helping to protect and prolong the life of water heaters, dishwashers and washing machines. It functions by wrapping two antenna cables around the main water pipe to form a coil, creating a complex, frequency modulated, electronic magnetic waveform. This induces an oscillating electric field into the water, resulting in the agitation of water molecules sufficient to trigger the release of carbon dioxide (CO2) which causes the premature precipitation of calcium bicarbonate. This process naturally results in a tiny increase in solubility, which allows the now unsaturated water to dissolve existing scale deposits and remove them from the water system. Limescale deposits on your fixtures will soften after regular contact with the treated water. This allows for easier cleaning without the use of chemicals. Deposits on showerheads, sinks and faucets will easily wipe off or disappear. The treated water will allow soap to lather up more effectively, leaving your skin feeling smoother and your hair more manageable. Enjoy healthier and better tasting water, as well as brighter, whiter and longer lasting clothes, towels and sheets!

Simple Installation

In summary, the ED2000 is a more affordable alternative to water softening systems and offers many distinct advantages. Applied externally on the water pipe, it requires very little maintenance as it does not need the constant salt additions or cartridge replacements that traditional water softening systems do. Installation is very simple and requires no changes to your plumbing. With all of the benefits, the ED2000 Electronic Water Conditioner provides a great addition to any household looking to improve their water quality.
