At the opening ceremony of the Beijing Winter Olympic Games, the colorful masks in the audience were like a blooming ocean. This very comfortable looking mask is actually an N95 mask.

How to make N95 mask more comfortable to wear while ensuring product performance? The "addition" of the two key parameters of middle nasal width and middle nasal height makes the opening ceremony mask face closer and more comfortable to wear.

The reporter saw that the masks worn by the audience in the auditorium are particularly bright, including light blue gradient, dark blue gradient, light purple, positive purple, Chinese red, glow red and other colors. The masks have Chinese elements such as Beijing Winter Olympics elements and snowflakes.

It is reported that this mask is a variable plane cavity structure mask independently developed and designed in China. It is completely designed, patented and made in China.
