Hi Folks! It’s been nine months since the coronavirus pandemic. We have been on our toes to fight the virus: wearing a face mask when stepping out, washing hands for 20 seconds along using hand sanitizer.
We have been maintaining social distancing and self-quarantine to beat the COVID-19 virus spread. Now that winter is near, and people tend to spend more time indoors in the cold, scientists and engineers believe that adequate air ventilation is also an essential aspect to avoid the spread of coronavirus. There is a new theory on how we breathe inside buildings matters. And how in-built ventilators have their own pros and cons.
