Eliminatr Water SoftenerEliminatr™ Water Softeners
The Eliminatr™ employs a special mesh cation exchange resin that gives it a much higher capacity for hardness and iron reduction. The new technology Vortech tank is used to allow high flow volume and reduce pressure drop. In addition, the Eliminatr™ uses less water and has more capacity per pound of salt than traditional systems.

Alternating Twin Water SoftenerAlternation Twin Water Softeners
The versatile Alternating Twin Softener employs one tank while the other remains in stand-by mode. When the integral water meter indicates regeneration is needed, the second tank come on-line while the first tank regenerates. This allows for an uninterrupted soft water supply. The newly regenerated tank is now in standby mode until the meter triggers the next cycle. There's no doubt that CSI Alternating Twin Softeners are the finest in the industry!
