Disposable masks, as the name suggests, refer to masks that are disposable and cannot be reused. This kind of mask is small in size, light in weight and thin in thickness, so if its protective ability is to be relatively strong, its process is required to be more complicated.
We know that masks are used to filter toxic and harmful gases or dusty substances. However, after a long time of use, the filter layer inside the mask will be blocked by various tiny particles, or the mask will lose its protective function because the moisturizing gas is exhaled from the mouth and nose.
Therefore, disposable masks generally lose their function after a period of use, or the protective layer collects a lot of fine dust, which blocks the tiny pores, and it will also feel difficult to breathe after wearing it.
