Culligan Aqua-Cleer Advanced Drinking Water System

The Aqua Cleer Advanced Drinking Water System uses costly proprietary filters that can only be purchased through an authorized Culligan dealer. While it offers multiple cartridge options, availability may be limited in certain regions, such as California, where membrane capacity is restricted to 30 GPD. If your Culligan system was installed between 2008 and 2020, it’s likely the Aqua Cleer Advanced model.

Alternative Option: To reduce costs, save water, and produce purified water faster, consider converting to the PuROTwist Retrofit Kit (PT4000T75-RK). This conversion kit allows you to use PuROTwist filters with your existing Culligan faucet, tank, and tubing. Start saving on replacement filters today!

IMPORTANT: The PuROTwist filter kits below only work if you convert your Culligan Aqua Cleer system with the PuROTwist Retrofit Kit (PT4000T75-RK)

Replacement Filter Info

Helpful Filter Information

Not all filters have the same replacement schedule. Replace the RO membrane filter every two years. Replace all other filters every 6-12 months. Help keep your system sanitary by never using filters longer than 12 months, except the RO membrane filter, regardless of how much water you use.
