Get a fresh take on drinking water with the Pentair OMNIFilter QuickConnect Tankless Reverse Osmosis System. Installed under your sink and connected to a dedicated smart faucet, this three-stage system uses a composite pre-filter, a carbon filter, and a reverse osmosis membrane to reduce a broad range of dissolved impurities, turning ordinary tap water into clearer, more refreshing water with the turn of the tap. The tankless design saves cabinet space with no bulky storage tank, and quick-connect cartridges twist out and lock back in within seconds, so there is no need to shut off the water for a filter change. An LED indicator on the smart faucet and on the system shows filter life at a glance, turning from blue to purple to red as a cartridge nears the end of its life. Tested and certified by NSF International to NSF/ANSI Standard 58, the system reduces Total Dissolved Solids by up to 96.8 percent and produces up to 396 gallons of filtered water per day. Replace the Composite and Carbon filters about every 12 months and the reverse osmosis membrane about every 24 months. The system arrives with everything you need to install it, including the smart faucet, power adapter, tubing, quick-connect fittings, and an easy-to-follow manual.
