Signature Series® Highlights

Superior Design

Twin Tanks

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

Non-Electric Operation

Non-Electric OperationPowered by water flow (kinetic energy) instead of electricity, there are no electrical components to repair or replace.  You can count on Signature Series water softeners to solve your hard water and soluble iron problems without creating new ones.

Hassle-Free, Reliable Operation


On-DemandThe 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

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