CleanAirKits is an innovative air purification company focused on making clean indoor air accessible, affordable, and effective for everyone. Founded in 2022, the company emerged from a global community of engineers experimenting with improved versions of the Corsi-Rosenthal box—an open-source air filtration design aimed at reducing airborne pollutants and viruses.

The company specializes in designing and producing DIY and pre-assembled air purifier kits that combine high-efficiency filters with advanced, ultra-quiet PC fan technology. This approach allows CleanAirKits to deliver powerful air cleaning performance while remaining energy-efficient and significantly quieter than traditional HEPA purifiers.

CleanAirKits products are engineered to help reduce airborne risks such as allergens, smoke, and viruses—including illnesses like flu and COVID-19—by continuously filtering indoor air. Their systems are designed to be quiet enough to run all the time, providing consistent protection in homes, schools, and workplaces.

All units are hand-assembled and shipped from the United States, with a strong emphasis on quality, simplicity, and user-friendly design. The company also supports educational initiatives, offering STEM kits that teach students about air quality, engineering, and hands-on problem solving.

At its core, CleanAirKits is driven by the belief that everyone deserves access to clean, healthy air. Their mission is to provide high-performance air purification solutions that are both affordable and practical, helping individuals and communities improve indoor air quality and overall well-being.
