After a severe shortage in the early days of the Covid-19 pandemic, there are now thousands of different types of masks available on the market. Since April 2020, CDC has tested hundreds of different brands. The table below shows some of the top-performing masks based on the most important measure - filtration efficiency. While big names like 3M and Honeywell performed very well in these tests, some lesser-known names came out on top.
B.1.1.7 Alpha: This variant was first detected in the United States in December 2020. It was initially detected in the United Kingdom.
B.1.351 Beta: This variant was first detected in the United States at the end of January 2021. It was initially detected in South Africa in December 2020.
P.1 Gamma: This variant was first detected in the United States in January 2021. P.1 was initially identified in travelers from Brazil, who were tested during routine screening at an airport in Japan, in early January.

B.1.1.529 Omicron: Includes BA.1, BA.2, BA.3, BA.4, BA.5 and descendent lineages. It also includes BA.1/BA.2 circulating recombinant forms such as XE. WHO emphasizes that these descendant lineages should be monitored as distinct lineages by public health authorities and comparative assessments of their virus characteristics should be undertaken.
In Europe, due to the rapid spread of the variants, governments are mandating medical-grade masks in public spaces such as airports and mass transit.
“The overall picture is one of something like a 40 to 60 percent increase in hospitalization risk, and risk of death,” Neil Ferguson, an epidemiologist and scientific adviser to the British government
German Chancellor Angela Merkel, with a Ph.D. in quantum chemistry from the Central Institute for Physical Chemistry at the Academy of Sciences in Berlin-Adlershof, has made KN95 masks her PPE of choice and has been photographed with these masks often in the last several months. Powecom seems to be her go-to KN95 brand while she has also been photographed with other KN95 masks with no clear brand identification.
