![HOW TO BUILD A CORSI-ROSENTHAL BOX
The Corsi-Rosenthal Box is an affordable DIY air-cleaning system made with simple materials found in hardware stores. The box fan pulls air through the filters on the sides and blows out clean air. It is proven to reduce indoor exposure to airborne particles including those containing the virus that causes COVID-19. The box can also decrease the levels of other particles in the air, such as dust or wildfire smoke.
• Filters can last up to a year
• Keep away from walls and corners

THE MATERIALS
THE CUBE
• Filters 3M 1900 MPR (20" x 20" x 1" or 20" x 25" x 1") or MERV 13 (20" x 20" x

• Cut the cardboard to fit the base of the cube.
• Duct tape it on all four sides
THE FAN
• Place the fan on top of the cube
• Seal all sides, including corners
• Ensure any holes on the side of the fan are sealed off with duct tape
THE SHROUD
