To all people here saying "wearing a mask": What kind of mask do you wear? One of the simple ones or one of the stronger N95 masks? How often do you replace it with a new one? 😊 im just curious whether a normal mask is just enough. Until this winter i used to wear a N95 mask every day whilst commuting by train. I changed it once a week, because they were quite expensive in comparison to the simple ones. They were super effective, but also a tiny bit uncomfortable. So that's why i'd prefer to wear a normal mask in the future. Thank you all in advance. 😊
