Is it better to wear a mask with a breathing valve or not?

A mask without a breathing valve is better.

A mask without a breathing valve may not feel smooth, but it can protect both the wearer and the other person, which is two-sided. Therefore, if you are going to a crowded place, it is recommended to wear a mask without a valve, which will be safer. It is not recommended to choose a mask with a breathing valve.
