Design Of Respiratory Masks For Non-medical Purposes

Respiratory masks are protective apparatus that cover the nose and mouth area in order to filter air breathed in by the wearer. They are designed for non-medical purposes like against pollution, smoke, and airborne particles such as dust, pollen, and other allergens. A well-designed respiratory mask must meet certain criteria to effectively filter and purify air. The mask must have a comfortable fit without causing any pressure on facial or nasal features. It must also have a proper seal that doesn't allow air to pass through the sides or bottom of the mask. The main filtering mechanism of the mask should be selected according to the specific pollutants present, either active carbon filters, HEPA or N95 filters. Choosing an appropriate material for the mask is a crucial step as the layer closest to the face should be soft, non-irritating and non-allergic while the outer layer must be water repellent and durable. The filter's maintenance and replacement must be easy, and the mask should be reusable and easily washable to provide much-needed affordability to regular users. Additionally, the design of the mask should be visually appealing which may encourage people to wear it as a fashion accessory regardless of the severity of the air quality.
