Made from everyday items found in hardware stores, the Corsi-Rosenthal box is a testament to the power of grassroots innovation.
How it all started, back in 2020.
Though Corsi calls it “embarrassingly simple,” the Corsi-Rosenthal box delivers significant reduction in particulate spread in indoor settings.
Covid is not going away for the foreseeable future. Vaccination, rapid tests and appropriate masking are important ways to protect against getting sick and spreading the virus. So is better indoor air quality.
What can you build with duct tape, air filters, and a box fan?
This might sound like the set up for a dad joke, but according to new insights from 3M, the answer is less of a punchline and more a breath of fresh air.
Presentation
Our results demonstrate that our Corsi-Rosenthal air cleaner efficiently reduces suspended particle concentrations in indoor environments.
A study from researchers at Brown University and Silent Spring Institute found that inexpensive, easy-to-assemble Corsi-Rosenthal boxes can help reduce exposure to indoor air pollutants.
“DIY air cleaners appear to be a valuable, low-cost tool to reduce hazardous PM exposures.”
