As wildfire smoke from Canada continues to impact the East Coast, residents are turning to a do-it-yourself air purification method known as the Corsi-Rosenthal box. This cost-effective solution, gaining traction on social media platforms like TikTok and Facebook, involves combining a box fan with four air filters and duct tape.
The method has been particularly helpful for those unfamiliar with wildfire smoke, unlike residents of the West Coast where wildfires are more common. Searches for "air purifiers" have surged on Google as people seek ways to protect themselves from the hazardous air quality.
The Corsi-Rosenthal method involves creating a box-like structure using four 20x20 inch air filters secured with duct tape. A box fan is then placed on top, creating a powerful and affordable air purification system for under $100. Videos demonstrating the construction process have gone viral, accumulating hundreds of thousands of views.
Experts confirm the effectiveness of these DIY purifiers. They highlight their high clean air delivery rate, capable of filtering out not only smoke particles but also pollen and viruses. Researchers have conducted tests in various settings, including universities, schools, and homes, demonstrating the purifier's ability to quickly clear the air of harmful particles.
The Corsi-Rosenthal purifier originated from a design shared on Twitter by Richard Corsi, dean of the College of Engineering at UC Davis. Jim Rosenthal, CEO of Tex-Air Filters, then brought the design to life. The goal was to create an affordable and accessible solution for the average person. Now, Corsi is receiving feedback from friends in the Northeast who are benefiting from his invention.
The purifier's popularity highlights the power of social media and community sharing in times of need. Individuals are sharing their experiences and DIY instructions online, enabling others to quickly and easily build their own purifiers. The accessibility of information and materials has made this an effective solution for many facing the challenges of poor air quality.
The widespread adoption of the Corsi-Rosenthal method underscores the importance of having accessible and affordable air purification options during environmental crises. As wildfire smoke and other air quality concerns continue to impact communities, this DIY solution empowers individuals to take control of their health and well-being.
