Under Sink and UnderCounter Water Filters

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 holding housing set that's installed under counter , usually into a kitchen cabinet. Undersink Filter is then connected to cold water line to deliver clean drinking water of great taste and high purity. The second option is in a different category, Under Counter Reverse Osmosis Purifiers. We offer standard 2.5"x10" cartridges in our Crystal Quest systems and non-cartridge systems.

All systems come with installation hardware, faucets, filters and a manual ready to be installed. Standard manufacturer warranty (usually 1 year applies). In cartridge type systems, filters should have to be replaced regularly to maintain proper filtration and to retain warranty.
