Air filtration has become an important tool in fighting the spread of Covid-19. The disease is spread by aerosolized particles that can linger in the air for some time before settling. Masks help prevent the particles from entering the air we share with others – air filters are a good way of dealing with the viral material that finds its way into the air despite our best efforts.
Unfortunately, commercial air filters are expensive. It’s easy to spend hundreds or thousands of dollars on portable ones.
Thankfully, creative scientists and DIY types have developed the Corsi/Rosenthal box (named for its co-creators). This cube-shaped contraption can be built in about 20 minutes and costs around $100, but performs as well as a unit costing five times as much. Corsi/Rosenthal boxes are being deployed in schools and offices around the country as colder weather drives people inside.
As part of our effort to make our building safer for staff and guests, we’ve installed three Corsi/Rosenthal boxes around the building. They’re an extra layer of defense as we spend more time indoors.
Please don’t touch or move the boxes unless you’ve checked first! They need to be handled with care, since virus particles will collect in the air filters that make up the four sides of the cubes. If you touch the filters, please wash your hands thoroughly right away, just to be safe.
And if you’re asked to move one of the boxes, please hold it by the plastic fan, and go slowly, so as not to shake any virus particles loose from the filters as you go.
We’re grateful that God has blessed us with such creative and resourceful neighbors with the ability to invent such a useful device!
