The ClearWave is a time-tested product that conditions water without using salt, chemicals or changes to plumbing. ClearWave treated water acts like soft water even though we don't remove the calcium. We use computer generated clearwaves to alter the calcium particles so they don't stick to each other or to your plumbing. These changed particles help dissolve existing scale and help prevent new scale from forming. This ClearWave treated water continues to dissolve scale as it flows downstream. Over time, the ClearWave helps solve hard water problems in the entire system, including pipes, water heater, shower heads and appliances.
