Air conditioning units that recirculate the same air in the room or building should be turned off or with the windows open to prevent the spread of the CCP virus, health experts have said.
“The recommended strategy now, if you have one of these split units, is to throw the window open and sacrifice your desire for a cold or cooler environment. If there is a modicum of wind it will move the air around. If you can’t open a window turn the unit off,” he remarked.
Dr. Julian Tang, a consultant virologist at Leicester Royal Infirmary, also issued a warning about air conditioning units.
“If you’re sitting underneath an air conditioning unit it might create a situation where you could spread the virus around,” he said. “Warm air will go over the coils and the air conditioning unit won’t filter any virus or fungus and it may serve to disseminate any infected plume.”
Tang noted that the CCP virus is believed to thrive in colder conditions, including those produced by air conditioners.
Edward Nardell, professor of medicine and of global health and social medicine at Harvard Medical School (HMS), also noted that air conditioners could help the spread of the virus.
Nardell noted that due to hot temperatures outside and “as people go indoors in hot weather and the rebreathed air fraction goes up, the risk of infection is quite dramatic.”
