Your AC May Spread Covid

Air conditioning units that recirculates the air in a room should be switched off or used with open windows.

Air conditioning units that only used recirculated air could spread the virus particles if someone was infected with Covid-19.

There are two types of air conditioning units - ones that takes air in from the outside or those that recirculate the same air.

Air conditioning units that do not have a “dedicated source of outside air supply into a room… could recirculate and spread airborne viral particles into the path of socially distanced users”.

Opening a window while operating the unit is the best way to mitigate risk.
