The Crystal Quest Alkaline Water Filtration System, SMART Countertop Single Cartridge is a point-of-use drinking water filter designed to sit on the countertop and connect to a compatible kitchen faucet. It uses a single replaceable cartridge with seven stages of filtration, including one-micron filter pads, coconut shell granular activated carbon, ion exchange resin, Eagle Redox Alloys 9500 and 6500 media, and ionizer media. The ionizer media contains magnesium and calcium to help increase oxygenation and drive pH higher. A diverter valve lets users switch between filtered and unfiltered water at the faucet. With a listed 0.3–0.5 GPM flow rate, this countertop alkaline water filter is suitable for drinking water use in homes, apartments, offices, and spaces where countertop faucet-connected filtration is preferred.
This Crystal Quest system combines alkalizing support and SMART filtration media in one countertop cartridge. It is designed for point-of-use drinking water applications where a compact faucet-connected countertop system is preferred.
Water travels through one-micron filter pads, coconut shell granular activated carbon, ion exchange resin, Eagle Redox Alloys 9500 and 6500 media, and ionizer media. These stages are designed to help remove or reduce suspended particles, bad taste and odors, heavy metals such as lead, copper, and aluminum, chlorine, chloramines, pesticides, herbicides, pharmaceutical by-products, petroleum byproducts, and other listed contaminants when present in the water.
The alkalizing stage uses ionizer media containing magnesium and calcium to help increase oxygenation and raise pH. This gives buyers a faucet-connected countertop option for alkaline drinking water.
The system is available in white or stainless steel housing options. Both versions use the same single-cartridge countertop format and connect to a compatible faucet with a diverter valve and adjustable spout.
This single-cartridge countertop filter is built for everyday drinking water use where alkalizing support and compact faucet-connected filtration are the priorities. It is suitable for kitchens, apartments, offices, and spaces where countertop faucet-connected filtration is preferred.
Choose the white or stainless steel housing based on your counter space and appearance preferences. Both versions use the same faucet-connected design with a diverter valve for switching between filtered and unfiltered water.
