US experts say that air conditioners can spread coronavirus if they include an indoor air recirculation system.
Such air conditioners, which partially cool and drive the air in a circle, are widespread because they are cheaper and more economical. However, in the current situation, this increases the risks of picking up COVID-19 indoors. As temperatures in most states increase, the number of infections can also increase due to the operation of air conditioners.
“In June, those states where residents turned on a large number of air conditioners because of the heat showed an increase in the spread of COVID-19. Air recirculation is the reason, ”says Dr. Ed Nardell, professor at Harvard.
The expert says upgrading air filters and remodeling the air conditioning system is a real way to reduce the spread of COVID-19 in a room.
