Product Highlights

Tried and true engineering and design went into our Signature Series water softeners. If you are not faced with difficult water problems, yet you want your water to be better than it is, a Signature Series system is right for you. Its twin-tank design, combined with non-electric, demand operation mean your water issues will be history. And so will any hassles or inconveniences you may have experienced with other water systems. What you’ll have is an unlimited supply of soft water.

Twin Tanks
Kinetico Signature Series water softeners are modeled after our original twin tank, non-electric water softeners that have been solving the water problems of millions of people worldwide for decades.

Non-Electric Operation 
Powered by water flow (kinetic energy) instead of electricity, you can count on Signature Series water softeners to solve your hard water and iron problems without creating new ones. They’re reliable, economical and the perfect fit in many homes.

The beauty of a Signature Series water softener is its ability to monitor your water use and regenerate (clean) itself only when needed. If you use a lot of water, your water softener will regenerate more, or it may not regenerate for several days if water usage is low. This efficient approach saves salt, water, money and guesswork.
