In a proof-of-concept study appearing online Aug. 7 in the journal Science Advances, Fischer, Westman and colleagues report that the simple, low-cost technique provided visual proof that face masks are effective in reducing droplet emissions during normal wear.
“We confirmed that when people speak, small droplets get expelled, so disease can be spread by talking, without coughing or sneezing,” Fischer said. “We could also see that some face coverings performed much better than others in blocking expelled particles.”
Notably, the researchers report, the best face coverings were N95 masks without valves – the hospital-grade coverings that are used by front-line health care workers and surgical or polypropylene masks. But hand-made cotton face coverings also provided good coverage, eliminating a substantial amount of the spray from normal speech. Our masks were designed to provide the best safety level below medical grade masks, and fall within the cotton-made face coverings by addressing several safety categories:
Masks of Love WNC
was created in Western North Carolina in March 2020 as a response to our community shortage of PPE in the face of Covid 19. We created an all volunteer effort to get cloth masks into the hands of those that needed them most. Now, Masks of Love has grown into a business that is providing local jobs while staying committed to our mission of donating masks to our under-served neighbors. We have donated almost 10, 000 masks since we began. Learn more about our community partners here.
