Replace the RO membrane every 2 years. Replace all other filters every 6–12 months, and never use them longer than 12 months, regardless of water usage.

Culligan Aqua-Cleer Advanced Drinking Water System Replacement Filters
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)
