It is available in single, double, and triple configurations, with housing options in white polypropylene or stainless steel. The system uses a nitrate-selective cartridge designed to reduce nitrates from drinking water, with SMART and carbon block cartridge stages included on select configurations. A diverter valve lets users switch between filtered and unfiltered water at the sink. With a listed 0.5 GPM maximum flow rate, this countertop nitrate water filter is intended for drinking water use in homes, apartments, offices, and other point-of-use applications.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eCountertop Nitrate Filtration for Drinking Water\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis Crystal Quest system is designed for point-of-use filtration at the kitchen faucet rather than whole-house treatment.
