KN95 Better Protection than Cloth Masks By Far

24 de enero de 2022

"Cloth masks are little more than facial decorations. There's no place for them in light of Omicron," CNN medical analyst Dr. Leana Wen, an emergency physician and visiting professor of health policy and management at the George Washington University Milken Institute School of Public Health, recently said on "CNN Newsroom."

In crowded places, "you should be wearing a KN95 or N95 mask," which can cost a few dollars each, Wen added. Due to certain materials -- such as polypropylene fibers -- acting as both mechanical and electrostatic barriers, these masks better prevent tiny particles from getting into your nose or mouth and must be fitted to your face to function properly.

N95 masks are considered the standard here in the United States, while the KN95 is China’s equivalent. Both masks are made from multiple layers of synthetic material (typically a polypropylene plastic polymer) and are designed to be worn over the mouth and nose. And both masks must be able to filter out and capture 95 percent (the figure seen in the mask names) of 0.3-micron particles in the air.
