In urban and industrial environments, pollutants from car fuels, industries and factories are exposed as aerosols. These particles enter the human body through the respiratory tract and disrupt the activity of the respiratory system. Pulmonary infections and respiratory disorders are among the consequences of the microcircuits. For this reason, the use of respirator masks has been expanded to prevent contaminants from entering the mouth and nose. Among the most important factors determining the efficiency of the masks are the rate of particle adsorption efficiency and the amount of pressure drop on both sides of the mask during use. The use of nanofibers in the production of respiratory masks enables the absorption of fine-grained aerosols and increases the efficiency of the mask.
The use of nanometer fibers with a diameter less than 100 nm in the respirator mask has increased efficiency in preventing dust particles from passing and contaminating, according to air cleaner test code 34.
