Which Face Masks Offer the Best Protection Against COVID-19?
So, what type of masks are best for the new omicron COVID-19 variant?
Due to the highly transmissible omicron variant, some experts are advising the public to wear well-fitted high-filtration mask like N95 — typically used by health care workers in high-risk environments — amid concerns that the commonly used cloth and surgical masks might not offer enough protection.Either way, health officials say the best masks are the ones that cover your nose and mouth, and fit snugly so there aren’t any gaps on the sides of your face.
If you want added protection, experts also suggest wearing two masks or pairing them with a mask fitter to ensure they don’t leave any gaps.An N95 mask is a filtering facepiece respirator . The Federal Code of Regulations defines an FFR to be a negative pressure particulate respirator with a filter as an integral part of the mask or with the entire face mask composed of the filtering material. An N95 means the mask has been rated to filter at least 95% of airborne particles it encounters.
The difference between an N95 and a KN95 mask is where the mask is certified. Masks have different approval sources and names based on countries of origin. Those produced in the U.S. and certified by the National Institute for Occupational Safety and Health are called N95, R95 or P95. In China, they are referenced as KN95 and in Europe they are called FFP2.
