In the middle of the outside and the inside is a filter layer that works to prevent droplets from splashing, the mask must filter dust, bacteria, which determines the quality of the mask. A proper filter layer must let the air easily pass through, creating ventilation for the user but must have a compact enough structure to filter out tiny particles of dust and bacteria.
