Reverse Osmosis Systems

Culligan Aqua-Cleer Advanced Drinking Water System

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 PT4000T75-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 PT4000T75-RK retrofit kit and PuROTwist filters!

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.
