Under Sink water filters are point-of-use systems used to filter tap water in the kitchen. The systems are installed under counter and provide filtered water through a separate faucet. A typical Under Counter System consists of a faucet that is installed near existing kitchen faucet, and typically a single, dual or triple cartridge system that is installed under counter into a kitchen cabinet. Undersink Filter is then connected to cold water line to deliver clean drinking water of great taste and high purity. We offer standard 2.5"x10" cartridges in our Crystal Quest systems.
