Apple Faces Class Action Lawsuit Over PFAS Chemicals in Watch Bands

Apple is now at the center of a class action lawsuit alleging that certain Apple Watch bands contain high levels of PFAS—commonly referred to as “forever chemicals”—without adequately informing customers of their presence or potential health risks. PFAS are known for their extreme durability, as they do not break down naturally in the environment and can persist for prolonged periods. These chemicals can accumulate in the body over time and have been linked to serious health concerns, including increased cancer risks, immune system suppression, and harm to unborn children. While studies continue to evaluate the full extent of these risks, concerns about PFAS exposure are mounting.

According to the lawsuit, which was first reported by The Register, the case was filed in the Northern District of California this week. It specifically calls out three Apple Watch bands: the Sport Band, Ocean Band, and Nike Sport Band. All three are made from fluoroelastomer, a fluorocarbon-based synthetic rubber renowned for its durability and resistance to sweat and skin oils. However, it is these very materials that are now being scrutinized for their alleged harmful chemical composition.

Study Linking PFAS to Watch Bands

The lawsuit references research conducted by scientists at the University of Notre Dame, who last year tested 22 fitness tracker and smartwatch bands, including some made by Apple. The study discovered elevated levels of PFAS, particularly perfluorohexanoic acid (PFHxA), in a number of these samples. Although the study does not explicitly identify which Apple bands were tested, it does highlight Apple and Apple/Nike products as containing concerning levels of PFAS. The researchers also noted that many of these bands are marketed to sports and fitness enthusiasts, who are likely to experience prolonged contact with the bands during activities that increase sweat and open skin pores. This could potentially heighten exposure to the harmful chemicals, allowing them to seep into the skin and bloodstream.

Allegations Against Apple

The plaintiffs in the lawsuit claim that Apple is aware of the presence of PFAS in its watch bands and the associated health risks. They have accused the company of violating California’s consumer protection laws, engaging in fraud and negligence, and unjustly enriching itself. The lawsuit demands an injunction to halt sales of the affected watch bands, as well as monetary penalties for the alleged violations.

The complaint also criticizes Apple’s failure to use safer manufacturing alternatives despite their availability. Furthermore, the lawsuit argues that Apple’s continued marketing of its products as promoting health, wellness, and sustainability while using potentially harmful materials is deceptive. Specifically, the complaint reads:

“[Apple] could have avoided the unreasonable safety and environmental hazard with available manufacturing alternatives, and its failure to do so while continuing to promise consumers health, wellness, and sustainability is unlawful, unfair, and fraudulent under consumer protection laws.”

Marketing Concerns and Consumer Risks

The University of Notre Dame study emphasized that many smartwatch bands, including those from Apple, are promoted as ideal for active lifestyles. However, wearing these bands during exercise increases the risk of exposure, as sweat and open pores create easier pathways for PFAS absorption. Although the lawsuit mentions three specific bands—Sport Band, Ocean Band, and Nike Sport Band—it remains unclear if these were among the bands tested in the Notre Dame research.

What’s Next?

The lawsuit aims to bring attention to the safety concerns surrounding wearable technology and to push Apple to address the alleged risks associated with its watch bands. As the case unfolds, it raises broader questions about the materials used in consumer tech products and the responsibility companies have to ensure their safety.
