Crystal Quest SMART Under Sink Water Filter System

The Ultimate Filtration for Safe, Healthy Water

Advanced Multi-Stage Filtration in a Compact, High-Performance System

The Crystal Quest SMART Under Sink Water Filter System delivers comprehensive protection against harmful contaminants including chlorine, heavy metals, VOCs, bacteria, pesticides, and more. With proprietary SMART filtration media and a compact design, it offers long-lasting, cost-effective purification—without taking up valuable space or relying on bottled water.

Ideal for homes, offices, and commercial kitchens, this under-sink unit provides high-quality, great-tasting water directly from your tap.

The Science of Clean Water & Your Health

Tap water often contains trace levels of industrial chemicals, heavy metals, and pharmaceutical byproducts that can accumulate in the body over time. According to the Environmental Working Group, even regulated water sources may still contain contaminants that pose health risks. The SMART Under Sink Water Filter System uses Crystal Quest’s proprietary SMART media, designed to address a broader spectrum of modern pollutants—including PFAS, prescription drug residues, and agricultural runoff. Backed by carbon filtration, redox alloy, and ion exchange resins, this system not only purifies but also protects—ensuring clean water you can feel good about drinking.
