Water Deionizers

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

Clear deionizers let you see when it’s time to replace the cartridge without stopping flow. They 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.

Quick-Change Water Deionizers

One-Cartridge Deionizer

Two-Cartridge Deionizer

A quarter turn releases the cartridge in these deionizers for speedy replacement. Deionizers with higher water resistivity produce a better quality of water.

Two-cartridge deionizer comes with a digital meter that indicates when to replace the cartridge.

(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-Capacity Plastic Filter Housings
with Cartridge for Drinking Water

Also known as reverse osmosis water filters, these have several cartridges that reduce odor, rust, sediment, and lead from drinking water, as well as a tank to store filtered water. Filter housings have an additional prefilter to protect the reverse osmosis cartridge from damage caused by particles and chlorine. They are opaque white so they block light to minimize algae growth.

Faucet-Mount Plastic Filter Housings
with Cartridge for Drinking Water

Tap into great-tasting water by screwing this filter directly onto your faucet. It comes with a cartridge that filters out sediment, chlorine, and other particles that cause unpleasant tastes and odors. The cartridge lasts approximately two months or 200 gallons of water. Filter housing is opaque white so it blocks light to minimize algae growth. It is not recommended for hot water.

Plastic Filter Housings with Cartridge for Drinking Water

Prepare water for use in beverages, food preparation, and ice production. This filter housing comes with a cartridge that prevents scale formation, which can damage equipment. Filter housing is opaque blue so it blocks light to minimize algae growth. It has a flow-control valve that allows you to stop the flow to replace the cartridge. It comes with adapters and a length of tubing for under-sink installation between a water line and faucet. Filter and cartridge meet NSF/ANSI Standards 42 and 53 for use with drinking (potable) water.
