Yes, but they likely are not as comprehensive. While many standard refrigerator, faucet and pitcher filters rely solely on carbon filtration, it’s only one of multiple stages of filtration that typical RO systems use to make tap water cleaner, safer and better tasting. For one of the most in-depth, targeted approaches to filtration, reverse osmosis systems are the best choice.

An RO system can be installed anywhere that has access to a cold water line and drain — such as a basement, crawl space or in an adjacent cabinet. This includes any size or type of home, apartment or condo. If you are renting, it is advised to check with your landlord before installing any water treatment system.
The AC-30 Good Water Machine requires a water pressure minimum of 40 psi to properly operate; most homes should be at or above this level. If you do have lower water pressure, a booster pump can enable usage of this system. If you’re unsure whether your water meets that requirement, contact your local Culligan water experts, who have extensive knowledge about local water conditions.
