The Crystal Quest Lead Countertop Water Filtration System is a point-of-use drinking water filter designed to sit on the countertop and connect to a compatible kitchen faucet. It is available in single, double, and triple configurations, with housing options in white BPA-free polypropylene or stainless steel. The system uses a 1/2-micron lead and cyst removal carbon block cartridge, with SMART and carbon block cartridge stages included depending on the selected configuration. A diverter valve lets users switch between filtered and unfiltered water at the sink. With a listed 0.3–0.5 GPM rated service flow, this countertop lead water filter is suitable for drinking water use in homes, apartments, offices, and other point-of-use applications.
This Crystal Quest system is designed for point-of-use filtration at the kitchen faucet rather than whole-house treatment. It provides lead-focused filtration on demand from the countertop, making it a practical fit for kitchens, apartments, offices, and spaces where countertop faucet-connected filtration is preferred.
The lead removal cartridge uses a 1/2-micron carbon block filter designed for lead and cyst reduction. Its listed capacity is 6,000 gallons, with actual performance depending on the detected lead level and influent parts-per-billion concentration.
The lead removal cartridge is the key cartridge in the system. The single configuration includes the lead cartridge, the double configuration adds the SMART cartridge, and the triple configuration adds both SMART and carbon block cartridge stages.
Buyers can choose white polypropylene housing or stainless steel housing. The polypropylene housing is listed as BPA-free, while the stainless steel option provides a different housing material and appliance-style countertop appearance.

This countertop lead water filter is designed for drinking water applications where compact faucet-connected filtration is preferred. It is a practical choice for homes, apartments, and offices where point-of-use lead reduction at the sink is needed.
Choose the configuration and housing material that fit your filtration needs and preferred cartridge layout. Single, double, and triple layouts offer flexibility, while white polypropylene and stainless steel options support different material and appearance preferences.
