A Czech company has developed the world's first nanofiber FFP3 respirator

The Czech project Pardam Nano4fibers has developed and started producing the world's first nanofiber FFP3 respirator, the Czech Nanotechnology Industries Association told CTK.

The firm, which is a member of the association, said the resistance to humidity increased thanks to the nanomembrane and the respirator can therefore be used as a protection from bacteria and viruses for several days if the users care for it properly.

Besides, the absence of an expiratory valve enables the users to protect not only themselves but also their surroundings since they do not release potential viruses and bacteria.

The Czech Nanotechnology Industries Association said that along with the certificate under the European standard, the BreaSAFE Classic FFP3 nanofiber respirator had also gained a certificate from the U.S. Nelson Labs confirming more than 99.5 percent capture of viruses and bacteria.

The current reproduction capacity of the Pardam Nano4fibers firm is 800,000 respirators a month and it was extended also thanks to the contribution from the Czech Rise Up program of the Industry and Trade Ministry.

Pardam Nano4fibers focuses on the research and development of nanofibers, their application, and, their use in the commercial sphere. It has been working in this field for more than ten years. The firm says on its website it is the world leader in the development and industrial production of inorganic nanofibers and polymeric nanofiber membranes.
