Water Deionizers

Deionizers remove dissolved ions, which reduces electrical conductivity and scale-forming minerals in water.

Clear deionizers have a pressure-relief valve that allows you to release pressure prior to replacing the cartridge.

Opaque deionizers are light-blocking to minimize algae growth. They have an indicator light to alert you when you should replace the cartridge or filter media.

Disposable Water Deionizers

Shown with Mounting
Bracket
(not included)

Designed for use in low-flow applications without back pressure, this deionizer has barbs on each end for connecting to tubing. It is clear so you can monitor debris collecting in the cartridge without stopping flow; replace the cartridge when the media changes color. Deionizers with higher water resistivity produce a better quality of water.

High-Purity Water Deionizers

These high-purity deionizers produce a higher quality of water than other deionizers for use in critical applications and sensitive equipment. They are opaque white so they block light to minimize algae growth. Deionizers have an indicator light to alert you when you should replace the cartridge.
