Oxygen C Mask

The outer layer of the mask tends to accumulate a lot of dirt in the outside air, such as dust and bacteria, and the inner layer is blocking the bacteria and saliva that exhale, therefore, both sides cannot be used alternately, otherwise the contaminated outer layer will be inhaled into the human body when directly sticking to the face, and become the source of infection.

When not wearing a mask, fold it into a clean envelope and fold the face close to your nose and mouth. Do not put it in your pocket or hang it around your neck.

The transmission rate of the middle part is the same as that of the edge part.
