Omicron is by far the most contagious variant we have encountered since the outbreak of covid-19, hence high-quality & high-protection masks are more important than ever. This is true for everyone, and even more so for those who are unvaccinated, at increased risk of serious illness, or caring for someone with COVID-19.
In high-risk areas, ordinary disposable masks are not recommended. High-quality KN95, KF94 and N95 masks not only offer good sealing, but also have at least 95% filtering efficiency against airborne particles.
Working and traveling is all about being comfortable and relaxing, so finding a comfortable N95 mask is very important. The three masks listed are the most popular and cost-effective n95 masks among users.
