Kinetico Signature Series Highlights

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.

Hassle-Free, Reliable Operation


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.

Softwater, Countercurrent Regeneration

Signature Series water softeners regenerate using soft water. With soft water regeneration, your system will work better and last longer.
