It is available in single, double, and triple configurations, with the installation valve selected based on the home’s under-sink plumbing. The fluoride cartridge is included in every configuration, while SMART and carbon block stages are added depending on the selected model. The fluoride cartridge uses media that Crystal Quest describes as having high affinity for fluoride, lead, and arsenic, with performance depending on source-water conditions. With a 1\/4\" connection size and a listed fluoride cartridge capacity averaging 1,000–1,500 gallons depending on source-water conditions, this under-sink fluoride water filter is intended for point-of-use drinking water applications in homes, apartments, offices, and similar settings where fluoride reduction is a treatment goal.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eUnder-Sink Fluoride Reduction for Drinking Water\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis Crystal Quest system installs beneath the sink to keep the filter housing off the countertop.
