This is a mask that can replace the filter element, and the inside is inflatable to ensure tightness, so that the mask completely fits the facial muscles. At the same time, the built-in small fan can avoid being too stuffy. Secondly, the mask can be folded and stored when not in use to ensure the cleanliness and hygiene of the inside. Finally, the material on the surface of the mask can be smeared to increase some personalization.

I like the prompt function very much.
Integrate too many ideas
This is too tight...
