Customized Filtration to Fit Your Needs
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:
Total Defense Cartridge
Add an extra layer of filtration for PFAS, pharmaceuticals, mercury, VOCs (volatile organic compounds), pesticides and more; you can also choose a Total Defense Cartridge with Mineral Boost.
Advanced Post Tank Filter
Expand protection to address bacteria and viruses; this filter is a particularly good option for well water.
Arsenic Filter
Focus on reducing arsenic in your water in areas where this issue is more significant.
Mineral Boost Cartridge
Add natural calcium minerals back into your water for great-tasting, optimally alkaline, pH-balanced water.
Premium Faucet
Choose from four modern designs in brushed nickel, chrome, matte black and bronze, and feel confident with every sip with real-time insights into filter life right from the optional integrated monitor light.
ClearLink PRO™
Instead of adding a faucet, use your existing one and switch between RO and tap water at the touch of a button with our proprietary wireless technology.
