Mask (English: Respirator, Mask) refers to a kind of appliance used to prevent the wearer from inhaling harmful components in the air, which can block smoke, vapor, gas, suspended particles such as dust and microorganisms of airborne diseases.
Most people think that surgical masks or similar masks can filter harmful substances in the air, but in fact, the main purpose of the design of surgical masks is to block the droplets of the wearer's nose and mouth, and the ability to filter particles in the air is extremely limited, let alone filter harmful gases in the air. In Japan, it is very common for people to wear masks in public during illness, which can prevent the spread of diseases. Some people often wear masks for other purposes.
