It is available in single, double, and triple configurations, with the installation valve selected based on the home’s under-sink plumbing. The SMART cartridge uses coconut shell and catalytic granular activated carbon, Eagle Redox Alloy 6500 and 9500 copper-zinc media, and ion exchange resin to help reduce chlorine, select heavy metals, taste, odor, and other contaminants referenced by Crystal Quest when present in tap water. The system has a listed 10,000-gallon filtered-water capacity and 1\/4\" connection size. It is a practical under-sink option for homes, apartments, and offices that need filtered drinking water without a countertop filter.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eUnder-Sink SMART Filtration for Drinking Water\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis Crystal Quest system installs neatly under the sink to keep the filter housing out of sight.
