PFAS "Forever Chemicals" Detected in Reusable Menstrual Pads and Underwear
A new scientific study reveals that eco-friendly menstrual products like reusable pads and period underwear can contain very high levels of toxic PFAS “forever chemicals.” About one-third of period underwear and one-quarter of reusable pads in the study showed signs of intentional PFAS use, likely added to increase leak-resistance.
PFAS (per- and polyfluoroalkyl substances) are synthetic chemicals linked to cancer, hormone disruption, reproductive issues, and other serious health risks. The study found especially high amounts of "neutral" PFAS, a type that is more easily absorbed through the skin and vaginal tissue, but which is not yet regulated or fully understood.
Researchers warn that there is currently no labelling to help consumers identify PFAS-containing menstrual products. However, the majority of products tested did not have high PFAS levels, showing that safer alternatives are possible.
Despite their eco-friendly claims, some reusable menstrual products may expose users to toxic chemicals. More research, transparency, and regulation are urgently needed to protect consumer health.

Puraffinity is pleased to announce that its G400+ adsorbent media has been certified to NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372 standards for Point of Entry (POE) and Water Treatment Plant End Use applications The certifications confirm that G400+ meets the required health effects criteria for materials used in drinking water system components. This milestone enables Puraffinity to support installations where NSF-certified products are required, including municipal drinking water applications. “As a member of the American Water Works Association (AWWA), I see this certification as an important step for broader municipal adoption, ” said Neal Megonnell, Chief Commercial Officer at Puraffinity. “It enables utilities to deploy our technology where NSF compliance is required, and it strengthens our ability to scale PFAS treatment solutions while maintaining the highest standards of safety and performance.” Designed for highly effective PFAS removal with rapid kinetics, the advanced adsorbent media G400+ supports compact system design and efficient treatment across a wide range of water matrices. Building on this milestone, the company continues to advance water treatment solutions that help utilities and industry address PFAS compliance and protect drinking water quality.
Puraffinity partners with the U.S. Army ERDC to evaluate Puratech G400, an advanced adsorbent for PFAS removal, through lab and field trials comparing its performance and cost-effectiveness to existing PFAS treatment technologies
Puraffinity signs first commercial agreement for full-scale deployment of its PFAS removal technology
An exclusive panel featuring Puraffinity CEO Vincent Caillaud, who will join industry leaders to discuss cutting-edge solutions for combatting PFAS, “forever chemicals”, in drinking water. With PFAS contamination presenting urgent health challenges due to their extreme persistence, mobility, and health impacts at trace levels, this session will spotlight the realities of PFAS in water supplies, the latest science driving regulatory change, and the next generation of removal technologies.
WEFTEC 2025 is the world’s largest annual water quality conference and exhibition, held September 27–October 1, 2025, at McCormick Place in Chicago. It gathers over 20,000 water professionals from 100+ countries to explore cutting-edge water technologies, attend technical sessions and workshops, and network with sector leaders. The event features a massive exhibition of advanced solutions, educational opportunities, and speciality pavilions focused on topics like sustainability and digital innovation. Our CEO, Vincent Caillaud , and CCO, Neal Megonnell , will be in attendance.
