Iran-Made Respiratory Nano Masks Provided to Hajj Pilgrims

Tehran, Iran | Posted on October 23rd, 2014

According to Dr. Reza Faridi Majidi, a member of the Scientific Board of Tehran University of Medical Sciences and Managing Director of Fanavaran Nano-Meghyas Company, commercial masks adsorb only less than 50% of dust at micrometric scale and the rest of the dust pass through the masks. However, the performance of the masks can improve up to 99% by using nanotechnology and by producing respiratory masks modified with nanofibers.

After two years of studying the production of modified masks, researchers of the company obtained the technical knowledge for the production of filters, and they commercialized the production of efficient respiratory masks modified with nanofibers.

Having the potential to produce 18 million pieces of masks per year, the company produces the masks, and it has allocated 500,000 masks to the Hajj pilgrims of Mecca.

Dr. Faridi explained about the advantages of the masks, and said, "In addition to adsorbing various types of suspended particles at micrometric scale, the masks are also able to block bacteria, fungi, and even viruses. These properties do not affect the respiration process, and respiration remains at desirable level."

Dr. Faridi explained how nanofibers had been produced through electrospinning method, and said, "In electrospinning process, the molten polymeric solution is sprayed to the opposite electrode due to the imposing of high voltage. Polymeric solution turns into nanofibers as a result of this transfer and nanofibrous felt is produced in the end."
