Filtered water pitcher usage in France

Approximately 20 percent of French households use a filtered water pitcher, typically kept in the refrigerator. These devices are designed to remove chlorine and other substances, making the water taste sweeter and more pleasant to drink.

Anses warns of bacterial risks

The French Agency for Food, Environmental and Occupational Health Safety (Anses) has raised concerns that these filters remove chlorine, which acts as a natural disinfectant. This can increase the risk of bacterial growth in the water if the device is not properly maintained.

Proper use and maintenance guidelines

Anses emphasizes that filtered pitchers should only be used with tap water that already meets health standards and cannot make non-potable water safe to drink. The agency recommends replacing the filter every 4 to 6 weeks, cleaning the reservoir regularly, and consuming the filtered water within 24 hours after refrigeration.

Chlorine’s role in water safety

Chlorine in tap water helps prevent the growth of harmful microorganisms. Removing it can create a more favorable environment for bacteria, especially if the pitcher is not cleaned or maintained according to guidelines. Manufacturers often highlight benefits like reduced limescale and heavy metals, but Anses confirms that most products meet basic standards for these aspects.

Need for standardized testing

Anses calls for standardized testing to ensure that all filtered pitchers meet their advertised performance claims. It also stresses the importance of following user manuals and maintenance instructions to keep filtered water safe and effective for daily use.
