The Aqua Cleer Advanced Drinking Water System is a Culligan reverse osmosis drinking water system, as is the Culligan AC-30. This Aqua Cleer system requires proprietary filters that are only available from Culligan Dealers. The Aqua Cleer Advanced Drinking Water System supports up to 14 different cartridges, though not all of the filters are available in all areas such as California where the membrane is limited to 30 GPD. This typically results in very expensive replacement filters with few benefits over a traditional RO system. If your Culligan reverse osmosis system is from 2008 or newer, there is a good possibility it might be a Aqua Cleer Advanced Drinking Water System.

If you're looking to replace your Culligan system with a similar cartridge based RO system, we recommend converting to the PuROTwist Retrofit Kit!

SAVE MONEY and convert your system with a PuROTwist Manifold & Filter kit PT4000T50-SS-RK.

Keep your existing faucet, tank, and tubing, then simply add the PuROTwist filters and manifold. Begin SAVING MONEY on your future replacement filters today by switching to the PT4000T50-SS-RK retrofit kit and PuROTwist filters!
