Cold Water Under Sink & Point-of-Use Filter System

The Santé Cold Water Under Sink Filter System connects directly to a compatible cold water line and filters all water flowing through that fixture or appliance.

Unlike systems that require a separate drinking-water faucet, this unit can be installed directly on the existing cold water supply line. Once installed, the connected faucet or appliance receives filtered cold water without requiring changes to your countertop.

Its compact, single-housing design accepts standard 10-inch by 2.5-inch cartridges, allowing the filtration media to be changed or customized as your needs evolve.

The standard system includes our exclusive Santé three-media blend cartridge:

• KDF 85
• SIR-900
• Centaur catalytic carbon

Together, these specialized media provide a versatile filtration solution for a range of common city and well water concerns.

Filter Cold Water Where You Use It

Install the system on a compatible cold water line beneath a kitchen sink, bathroom sink, refrigerator, ice maker, coffee maker, water dispenser, or other point-of-use application. The water is filtered directly before it reaches the connected faucet, appliance, or fixture.

Exclusive Santé Three-Media Blend

Each system includes our exclusive cartridge combining KDF 85, SIR-900, and Centaur catalytic carbon. This broad-spectrum media blend helps address chlorine, chloramine, fluoride, arsenic, certain dissolved metals, organic compounds, and unpleasant tastes or odors.

Fully Customizable Filtration

The cartridge can be tailored to your specific water quality, installation, and primary concerns. Send us your water-quality report or contact our team, and we can help determine whether the standard Santé blend or a customized cartridge is the best fit.

Versatile Point-of-Use Installation

This system is not limited to the kitchen. It can be used beneath bathroom sinks, before refrigerators and ice makers, with coffee makers and water dispensers, or anywhere else a compatible cold water line requires targeted filtration.

Filter Both Sides of Your Faucet

Pair the Cold Water Under Sink System with our Hot Water Under Sink Filter System to filter both supply lines feeding your existing faucet.

Install one system on the cold water line and one on the hot water line to receive filtered cold and hot water through the faucet you already use—without adding a separate countertop faucet.

Compact, Flexible Design

The single-housing design fits beneath many sinks and in other compact installation areas while using a standard 10-inch by 2.5-inch replacement cartridge. Its adaptable design also makes future cartridge changes and filtration customization simple.
