High-precision adsorption-type PFAS purification device "ECO Clean LFP" and "LFP Cartridge"
What has changed in the PFAS drinking water standards? | A summary of key points compared with numbers for implementation in April 2026.
Starting from April 1, 2026, PFOS and PFOA will be subject to the "water quality standards" under the Water Supply Act, transitioning from the previous "target values" to legally binding "standard values." The standard value is set at a total of 50 ng/L or less for PFOS and PFOA combined. 【What you can learn from this document】 ■ What regulations on PFAS have begun ■ What changes will occur with this standardization ■ How to respond Additionally, it explains cases that require caution, such as the use of well water, groundwater, dedicated water supply, and food and beverage factories, as well as the EU's perspective on addressing PFAS not only in drinking water but across the entire environment. 【Exhibition at the 2026 New Environmental Exhibition!】 May 20 (Wed) - 22 (Fri), 2026, Tokyo Big Sight We will showcase two models for PFAS countermeasures: "ECO Clean LFP" and the next-generation cartridge-type PFAS purification unit "LFP Cartridge." We will also hold a "mini individual consultation session" on PFAS countermeasures♪ ＼ Click "PDF Download" to view the materials ／
