Mia Heller, an 18-year-old student from Warrington, Virginia, has developed an innovative water filtration system that addresses the pressing issue of microplastic contamination in drinking water. Heller’s initiative stems from her concern over a local report indicating that the water quality in her community was severely compromised by PFAS and microplastics, prompting her to find a solution.
Microplastics, which are tiny plastic particles measuring between one nanometer and five millimeters, have increasingly been detected in human tissues, including brain, bones, and reproductive organs. The Environmental Protection Agency highlights the growing prevalence of these particles, with a significant rise in microplastic concentrations in human bodies since 1990. Drinking water is recognized as a crucial pathway for their entry into the human system.
Heller began her project in the spring of 2024, experimenting in her garage and kitchen to create a functional prototype by early 2025. The core of her design utilizes ferrofluid, a magnetic oil that binds to microplastic particles as water flows through the filtration system. The system consists of three modules: one for contaminated water, another for storing the ferrofluid, and a third for the filtration process. Using a magnetic field, the system effectively extracts microplastics from the water, recycling the ferrofluid in a closed-loop system.
Testing results indicate that Heller’s prototype can remove over 95% of microplastics, while recovering nearly 87% of the ferrofluid used in the process. This efficiency surpasses traditional water treatment plants, which typically remove between 70% and 90% of microplastics.
While Heller’s invention is currently designed for home use, she acknowledges the need for further verification of her results and practical considerations for scaling the technology. Despite the challenges, she envisions her system as an affordable, waste-reducing solution for households, offering a significant advancement over conventional filtration methods.
Heller’s work has garnered recognition, including being named a finalist at the 2025 Regeneron International Science and Engineering Fair, the largest high school science competition globally. As she continues to refine her technology, Heller remains focused on the goal of making her innovative water filtration solution available to the market, showcasing the potential for grassroots innovation to address critical environmental health issues.
