It is available in single, double, and triple configurations, with the installation valve selected based on the home’s under-sink plumbing. The system uses a ceramic cartridge listed for filtration as low as 0.5 microns, with SMART and carbon block filtration stages included depending on the selected configuration. The ceramic cartridge is listed by Crystal Quest for reducing\/removing certain bacteria, cysts, and sediment from water and can be cleaned up to 30 times. With a listed 0.5 GPM maximum flow rate and 1\/4\" connection size, this under-sink ceramic water filter is intended for point-of-use drinking water applications in homes, apartments, offices, and similar settings where ceramic filtration and routine cartridge maintenance are appropriate.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eUnder-Sink Ceramic Filtration for Drinking Water\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis Crystal Quest system installs beneath the sink to keep the filter housing out of sight and off the countertop.
