Nihon Trim Survey on Drinking Water: About 80% Unaware of April 2026 Tap Water Quality Standard Revisions

Nihon Trim Co., Ltd. (Headquarters: Osaka, President: Tsuneo Tahara), the market leader in water purifier sales, conducted a survey on drinking water among 500 men and women in their 20s to 60s nationwide. With the revision of tap water quality standards on April 1, 2026, which elevated organic fluorine compounds (PFOS/PFOA) to water quality standard items, attention is focused on 'water' as a life infrastructure. The survey revealed that traditional drinking styles are changing, with new habits focused on 'functionality' permeating, especially among the younger generation. 1. About 80% are unaware of the April 2026 tap water quality standard revision. 2. Drinking tap water directly is polarized by generation; the 'do not drink tap water' style is spreading among the youth. 3. 'Functional water' is a new selection criterion; over half have experienced it. 4. Women feel the benefits of sufficient hydration more than men. 5. Only 20% know that some household water purifiers are 'medical devices for improving gastrointestinal symptoms'. Nihon Trim will continue to provide health information as a medical device manufacturer and contribute to a healthier lifestyle through 'Electrolytic Hydrogen Water Purifiers'.
