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

The Santé Hot Water Under Sink Filter System connects directly to a compatible hot water supply line and filters the water flowing to that fixture.

Its durable, high-temperature housing is constructed from glass-reinforced nylon and is rated for water temperatures up to 200°F and pressures up to 125 PSI. This makes it a reliable alternative to conventional filter housings that are intended for cold water only.

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

• KDF 85
• SIR-900
• Centaur catalytic carbon

Together, these specialized media help address a broad range of common water-quality concerns, including chlorine, chloramine, fluoride, arsenic, certain dissolved metals, organic compounds, and unpleasant tastes or odors.

Filter Hot Water Where You Use It

Install the system on a compatible hot water line beneath a kitchen sink, bathroom sink, utility sink, or other point-of-use application. The water is filtered directly before it reaches the connected faucet 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 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 high-temperature cartridge is the best fit.

Designed Specifically for Hot Water

Unlike standard filter housings made for cold water only, this system features a durable glass-reinforced nylon housing rated for water temperatures up to 200°F and pressures up to 125 PSI.

Built Beyond Residential Standards

This system uses a durable glass-reinforced nylon housing engineered for demanding high-temperature applications, including residential, commercial, and industrial filtration. You receive that same heavy-duty construction in a compact point-of-use system designed for installation on a compatible hot water line.

Filter Both Sides of Your Faucet

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

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

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.
