The Crystal Quest Fluoride Removal + SMART Single Under Sink Water Filter System is a point-of-use drinking water filter designed to install beneath a sink and connect to the included faucet and installation hardware. It uses a single replaceable cartridge with seven stages of filtration, including fluoride removal media, one-micron filter pads, ion exchange resin, Eagle Redox Alloy media, and granular activated carbon. The fluoride removal cartridge has an average service range of 1,000–1,500 gallons, depending on source-water conditions and usage. This system is designed for municipal water with inorganic fluoride; Crystal Quest recommends contacting them for organic fluoride or natural/well-water fluoride applications. With a listed 0.3–0.5 GPM maximum flow rate, 1/4" connection size, and compact 5" L × 14" H × 5" W housing, it is intended for under-sink point-of-use drinking water applications where municipal inorganic fluoride reduction is the treatment goal.
This Crystal Quest system combines fluoride-focused media with SMART filtration media inside one under-sink cartridge. It is designed for point-of-use drinking water applications where fluoride reduction and the included faucet setup are preferred.
Water travels through pre and post one-micron filter pads, fluoride removal media, ion exchange resin, Eagle Redox Alloy 6500 and 9500 media, and granular activated carbon. These stages are designed to help reduce suspended particles, fluoride, select heavy metals, chlorine, chloramine, taste, odor, and other contaminants listed by Crystal Quest when present in the water.
Crystal Quest states that this fluoride system and media accommodate fluoride removal from municipal water that consists of inorganic fluoride. For organic fluoride or natural fluoride from sources such as well water, Crystal Quest recommends speaking with an associate for a system recommendation.
Select the installation valve based on the home’s under-sink plumbing and the installation manual. Verify whether a saddle valve or T-valve is required for the selected connection setup. A leak detector or flood-prevention valve may be considered as a recommended add-on for added installation protection where appropriate.

This single-cartridge under-sink filter is designed for drinking water use where fluoride reduction and compact under-sink placement are priorities. It connects below the sink and supplies filtered water through the included faucet setup.
Choose the correct connection type before installation. Valve selection should be verified against the selected under-sink plumbing setup, while a leak detector or flood-prevention valve may be considered for added installation protection.
