Powerful Tools Against Covid-19 Gaining Attention: Ventilation, Filtration

Experts are beginning to acknowledge additional ‘powerful tools’ that can be used to combat the Coronavirus… ventilation and filtration. Joseph Allen, director of the Healthy Buildings Program at the Harvard T.H. Chan School of Public Health says depending on the ventilation rate in the room you’re in, “as much as 3% or 4% of the air you’re breathing just came out of the lungs of other people in that room’ and if another person in the room has the virus those particles can make their way into your lungs too. The World Heath Organization and CDC have also acknowledged that Covid-19 could be spread by the particles. You can limit those particles by using filtration which it’s recommended that portable air filters are used and upgrading HVAC systems is important.
