Centralised AC ventilators do spread COVID-19 respiratory droplets but the role of Window AC in large spaces doing the same has not been determined.
The PIB's Fact Check stated that uses of window AC is ok in homes but the risk was with the central air conditioning system. According to experts, the use of window ACs in small spaces does not pose any additional risk of coronavirus infection, especially at a time when people are isolated inside their homes with no outside contact.
But it has not been researched or clarified whether the Window AC is safe or unsafe to be used in large(commercial) area/spaces during the COVID-19 crisis.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
