Get clean, filtered water on demand with the KRAUS Purita 2-Stage Under-Sink Filter System. The dual filter cartridge system with carbon block and polypropylene filters works to remove particles as small as 0.5-microns, reducing lead, select pharmaceuticals, VOCs, and chlorine odor for great-tasting water. Filters last for up to 6-months or 700 gal., and a digital display monitors water quality, battery life, and filter status, notifying you by beeping when you need to replace them to maximize filter life. Replacement filters (FC-100) are easy to install with a simple twist and lock quarter-turn mechanism. The under-counter design creates a clean look and is compatible with most standard filter faucets. Kit includes mounting hardware, tubing, quick connect adapter, and batteries.
