India's federal ministry of science and technology Monday said researchers have developed a reusable, recyclable, washable, odorless, non-allergic and anti-microbial N95 mask by using 3D printing technology.

According to the ministry, the four-layer mask whose outer layer is made up of silicon has a shelf life of more than 5 years depending upon the use.

"Apart from its well-known uses to prevent infections like COVID-19, the mask can also be used by workers in different industries where they are exposed to high volumes of dust like cement factory, brick kilns, cotton factories and paint industries," the ministry said.

It said a trademark and a patent have also been filed for the mask called Nano Breath having immense potential as a prophylactic.

The mask has been developed jointly by researchers from Amity University Haryana in collaboration with a researcher from the U.S. University of Nebraska, officials said.
