What is a air mask?

An air mask, commonly referred to as a face mask, is a protective covering worn over the nose and mouth to filter out harmful particles in the air, such as dust, pollutants, and pathogens. They are often made from materials like cloth, surgical fabric, or specialized filters, depending on their intended use. Air masks gained significant attention during the COVID-19 pandemic for their role in reducing the spread of respiratory viruses. Additionally, they can be used in various settings, including healthcare, industrial environments, and during outdoor activities in polluted areas.
