12-Year-Old Innovator Creates Low-Cost Virus-Removing Air Filter Adopted Across Connecticut

Twelve-year-old Eniola Shokunbi, a student from Connecticut, has captured national attention after designing an affordable, do-it-yourself (DIY) air filter capable of significantly reducing airborne viruses in classrooms. Built with everyday materials—such as a basic box fan, cardboard, duct tape, and standard HVAC furnace filters—her design costs only around $60 but delivers air-cleaning performance comparable to professional systems.

This simple but powerful device is based on the well-researched Corsi–Rosenthal Box concept, which gained popularity during the COVID-19 pandemic for its proven ability to reduce viral aerosols using inexpensive materials. According to U.S. Environmental Protection Agency (EPA) tests, air filters of this type can remove over 97% of viral particles in 30 minutes and more than 99% within one hour, making them a practical and effective solution for schools and indoor public spaces.

Statewide Support Through $11.5 Million Funding

Recognizing the impact and practicality of Eniola’s work, the Connecticut State Bond Commission approved $11.5 million to expand her design statewide. This funding will support the new program called SAFE-CT (Supplemental Air Filtration for Education).

Administered through the University of Connecticut (UConn), SAFE-CT will help produce, install, and monitor these DIY virus-removing filters in classrooms across Connecticut. The initiative aims to:

• Reduce the spread of viral illnesses

• Improve indoor air quality

• Support student health and attendance

• Create safer learning environments throughout the school year

Public health researchers have repeatedly emphasized the importance of proper indoor air filtration in reducing airborne disease transmission—an issue highlighted during the pandemic. The Corsi–Rosenthal Box design, which inspired Eniola’s project, has been validated in multiple peer-reviewed studies for its effectiveness in removing viral aerosols and fine particulate matter.

A Global Example of Youth Innovation and STEM Education

Eniola’s achievement has attracted attention not only in the United States but around the world. Her story is seen as a powerful example of the importance of STEM education, creative problem-solving, and youth-driven innovation.

Her invention shows that even with simple materials and a brilliant idea, a young student can develop life-saving technology that benefits entire communities. It also demonstrates how accessible engineering and science-based projects can inspire the next generation of innovators.

Eniola’s air filter continues to serve as a reminder that creativity, determination, and scientific curiosity can lead to solutions that protect public health and make classrooms safer for everyone.
