The Researchers from Amity University in Haryana and University of Nebraska, USA have jointly developed a reusable, odourless and anti-microbial N95 mask by using 3D printing technology. The four-layer mask whose outer layer is made up of silicon with a shelf life of more than five years can also be used by workers where they are exposed to high volumes of dust, cement and paint fumes.
It can be modified by changing the filter configuration according to the place in which it will be used and can help prevent severe lung diseases such as Silicosis, said a statement here.
A trademark and a patent have also been filed for the mask called Nano Breath.
A 4-layer filtration mechanism has been provided in the mask wherein the outer and first layer of the filter is coated with nanoparticles. The second layer is a high-efficiency particulate absorbing (HEPA) filter, the third layer is a 100 µm filter and the fourth layer is a moisture absorbent filter. The mask has been developed under the project funded by the Department of Science & Technology (DST), Union Ministry of Science and Technology.
