Indo-US team 3D-prints nanoparticle coated N95 mask with 5 year shelf life

Researchers from Amity University

Haryana (AUH) and the University of Nebraska, US, have developed a reusable, recyclable, washable, odourless, nonallergic and anti-microbial N95 mask by using 3D printing technology. The four-layer mask whose outer layer is made up of silicon has a shelf life of more than five years depending upon the use.

The mask can be modified according to the requirement 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. 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.
