A low-cost air cleaner can greatly reduce transmission of virus: modelling study
In a systematic modelling study in the journal Physics of Fluids, they have shown that these inexpensive units can greatly decrease the amount of airborne virus in these spaces, if used appropriately.

Scientists have proposed using a simple air cleaner with a box fan. In a systematic modelling study in the journal Physics of Fluids, published by the American Institute of Physics, they have shown that these inexpensive units can greatly decrease the amount of airborne virus in these spaces, if used appropriately.
A low-cost air cleaner can be easily constructed from a cardboard frame, topped by an air filter and a box fan. The air filter is placed between the fan and the cardboard base. The fan is oriented so that air is drawn in from the top and forced through the filter, discharging cleaned air downward.
