EFFECTIVE SEDIMENT REMOVAL – The 5-micron Sediment filter captures and reduces unwanted particulate material such as sand, silt, and rust from water which affect the taste and appearance of your water.
CARBON FILTER REDUCES CHLORINE – The second stage of your reverse osmosis water filter is a Carbon Block filter. The 5-micron activated carbon filter reduces chlorine and conditions the water.
COLOR-CHANGING DEIONIZATION – The mixed-bed deionization resin is necessary to reduce TDS to zero in the final stage of an RO/DI system. It uses Cations and Anions beads to remove TDS from water.

Product Description

You Pick the Connection Type

Simply remove the aerator from your kitchen or bathroom sink and use one of the included adapters to convert to a standard garden hose thread. Then use the included hose to 1/4" tubing adapter. Or connect directly to your washing machine spickot.

Float Valve Included

The included Float Valve makes it easy to fill tanks, containers and aquariums automatically. The float can be adjusted as needed. Simply drill a 7/8" hole and install with the included hardware

Auto Shut-Off Solenoid & Check Valve

The included ASO and check valve will shut-off the wastewater line when the filtered water line is stopped. This means the RO/DI unit can be plumbed to a water tap or use the included float valve.

1/4" Tubing & Easy Connectors

Use the included 1/4" tubing to easily plumb your Twist-In RO/DI unit. The tubing simply pushes into the press-fit connectors 5/8" and locks into place for a leak-free setup.

Translucent Cartridges

The sediment and DI resin cartridges feature translucent housings to view inside the cartridges. You can see when the sediment cartridge is discolored from filtering out the particulate and when the DI resin changes to tan color and should be replaced.

Specialty Plumbing Components

Special 90° Elbows make it easy to customize the installation of this RO/DI unit. This allows the unit to be used with an optional booster pump and/or pressure tank for drinking water applications.

Live in the NYC Area?

Based on information presented in the most recent Water Quality Report, you must use an additional pre-filter prior to the Twist-In RO/DI unit if you are on the NYC area water supply.

Are you on well water?

People on well water often have CO2 in the water that can quickly deplete the DI resin cartridge. If you are on well water, check for CO2 prior to purchasing the Twist-In RO/DI unit.

Chloramines in your water?

The Twist-In carbon cartridge removes chlorine from tap water. However, it does not remove chloramines. Check with your water company or test your water for chloramines prior to purchasing.
