Customize your Culligan water filter for your sink to your needs with up to seven stages of filtration and 14 filter options. Our smart RO system is certified to reduce over 70 contaminants, including viruses, bacteria, mercury, arsenic, PFOA/PFOS and lead, as well as 15 emerging contaminants.
All Culligan RO systems include drinking water filters that provide multiple stages of filtration. The core levels of filtration are the sediment/carbon pre-filter, the RO membrane and a post-filter, which provides comprehensive protection against a broad array of issues including total dissolved solids (TDS), heavy metals, chlorine, lead and more. You also have a choice of one- or two-year filters. Additionally, you can enhance your system with these options:
Add an extra layer of filtration for pharmaceuticals, mercury, VOCs (volatile organic compounds), pesticides and more; you can also choose a Total Defense Cartridge with Mineral Boost.
Expand protection to address bacteria and viruses; this filter is a particularly good option for well water.
Focus on reducing arsenic in your water in areas where this issue is more significant.
Add natural calcium minerals back into your water for great-tasting, optimally alkaline, pH-balanced water.
Choose from four modern faucet designs in brushed nickel, chrome, matte black and bronze, and check real-time insights into water quality and filter life on the electronic display.
Use your existing faucet to switch between RO and tap water at the touch of a button. The display also shares information on filter life and water quality.
Download the Culligan Connect App to get the most out of your system with alerts and in-depth information on water consumption, contaminants reduced, savings and more.
All our smart ROs have auto-shut off if a leak is detected. Add the external leak sensor for more protection against leaks in nearby pipes or water-using appliances.

RO systems filter contaminants from water by forcing them through a semipermeable membrane to separate contaminants as small as a single atom. Some of these contaminants addressed in this process include lead, mercury and chromium, among many others. Most RO systems also include additional stages of filtration including sediment filters, carbon filters and other advanced options for additional filtration capability.
