Iran's nanofiber mask filters finest pollutants

Isfahan University of Technology developed a five-layer nanofiber mask that guards the face against the finest pollutants in the air.

Suspended particles are too small to be filtered out, but nanofiber mask stops particles from getting through.

Nasim Shahbazi, who led the project, said pollutant particles get into our body by airflow, causing pulmonary infections and respiratory diseases.

She urged the use of nanofiber mask in industrial zones and parks as well as hospitals.

"Nanofibers increase the surface area for pollutant particles interception and also incur larger air resistance," she said.

Shahbazi added that the mask blocks out suspended particles of 0.3 microns (or micrometers) or smaller.

Haze is usually composed of pollutants in the form of tiny suspended particles or fine mists and droplets emitted from vehicles, coal-burning power plants and factories. Continued exposure to air pollution increases the risk of developing respiratory problems, heart diseases and lung cancer.
