Air conditioners may increase coronavirus infection

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.
