It is Time to Address Airborne Transmission of COVID-19
Lidia Morawska, Donald K. Milton and 239 scientists appeal to the medical community and to the relevant national and international bodies to recognize the potential for airborne spread of COVID-19.
There is significant potential for inhalation exposure to viruses in microscopic respiratory droplets (microdroplets) at short to medium distances (up to several
meters, or room scale), and they are advocating for the use of preventive measures to mitigate this route of airborne transmission.
Studies by the authors of the report (link below) and other scientists have demonstrated beyond any reasonable doubt that viruses are released during exhalation, talking, and coughing in microdroplets small enough to remain aloft in air and pose a risk of exposure at distances beyond 1 to 2 m from an infected individual.
How Well Do Masks Work? (Schlieren Imaging In Slow Motion!)
This PBS video show how masks work to help stop aerosols that can carry the COVID virus from getting into the air around us.
What face masks actually do against coronavirus
Created by VOX, this video shows how face masks can limit how far respiratory particles can travel. Face masks help capture respiratory droplets and help prevent any viruses from becoming aerosoled.
ABC 6 takes on Bill Nye's mask vs. candle experiment
ABC News in columbus, Ohio confirms Bill Bye's mask test. The Bandana clearly failed. However, they did not fold the banadana to create a mask like Matthew McConaughey suggests in his Bounty Hunter Bobby Bandito video.

"Masks may be more effective as a “source control” because they can prevent larger expelled droplets from evaporating into smaller droplets that can travel farther."

If you are a mask manufacturer and want your face mask to be considered for publication on our website, please send a sample supply for review along with a press release. We'll then donate your masks to local organizations including medical personnel and front line workers. Only quality masks will be considered for review and highlighted on our website.
