Arsenic & Nitrate Removal Systems


To address consumer concerns about arsenic in their water* Culligan, the leader in home water treatment solutions designed the only certified Whole-House Arsenic Reduction Filter on the market. The entire system has been tested and certified by the Water Quality Association (WQA) against NSF/ANSI Standard 53 for the reduction of total arsenic (pentavalent and trivalent).

The Culligan Arsenic Reduction Filtering System is designed to continually monitor arsenic media life. Homeowners are then alerted when the media needs to be replaced.

To alleviate any additional concerns regarding arsenic exposure, Culligan offers a telemetry and monitoring service. A modem, which can be connected to the filter or Remote Display, has the ability to automatically e-mail the Culligan dealership with information on operating parameters and alarm conditions.

With the Culligan Whole House Arsenic Reduction Filter, you get the confidence and peace-of-mind that only Culligan can deliver.
