The Crystal Quest SMART 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 includes a SMART water filter cartridge in every configuration, with carbon block and sediment cartridges added 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 system is suitable for drinking water use in homes, apartments, offices, and spaces where countertop faucet-connected filtration is preferred.
This Crystal Quest system is designed for point-of-use filtration at the kitchen faucet rather than whole-house treatment. It provides filtered water on demand from the countertop, making it a practical fit for homes, apartments, and offices.
The SMART cartridge is included in the single, double, and triple configurations. The double configuration adds a carbon block cartridge, while the triple configuration adds both a sediment cartridge and a carbon block cartridge for additional staged filtration.
The SMART cartridge uses Crystal Quest’s blend of two types of coconut-shell granular activated carbon, including catalytic carbon, Eagle Redox Alloys 9500 and 6500, and anion exchange resin. This media blend is designed to help reduce heavy metals, chlorine, chloramine, pesticides, herbicides, pharmaceutical by-products, petroleum byproducts, and other listed contaminants when present in the water.
Buyers can choose white polypropylene housing or stainless steel housing. The polypropylene option is listed as BPA-free, while stainless steel provides a different housing material and appliance-style countertop appearance.
This countertop SMART water filter is designed for everyday drinking water use from a countertop faucet-connected system. It is a practical choice for homes, apartments, and offices where filtered water at the sink is preferred.
Choose the configuration and housing material that fit your counter space and filtration goals. Single, double, and triple models offer different cartridge layouts, while white polypropylene and stainless steel options support different material and appearance preferences.
