Is it safe to drink tap water? According to the Kantar-Cieau 2024 survey, published on February 11, half of the French population (49% to be precise) consider the actions taken by public authorities to ensure tap water quality to be insufficient. Furthermore, 54% feel they are not sufficiently informed about emerging pollutants – PFAS (so-called "forever chemicals") and microplastics in particular.

Repeated warnings, including in official reports, about the declining quality of drinking water, massively contaminated by pesticides and their degradation by-products, are becoming increasingly worrying. Although expensive, plastic bottled water is no safer (when it comes to microplastics, in particular) and environmentally unsustainable. As a result, many homeowners are either installing or considering installing an individual filtration system. The Kantar-Cieau survey also revealed that 19% of French people questioned are trying to protect themselves from pollutants with a water filter jug, and 13% have installed a filter on their faucet.
