New Delhi, May 08 (ANI): Face masks, which have become a ubiquity since the outbreak of the COVID-19, may continue to be opted for by people, even after an easing of lockdown restrictions imposed to stem the curb of the virus. Be it homemade varieties in a riot of colours or the more distinctive surgical masks and the expensive N95 ones- the demand for masks are here to remain, according to experts, as a grim reminder of the times we live in. For this a technology startup which has partnered with Indian Institute of Technology Delhi (IIT-D) has developed a new affordable and efficient face mask named N-Safe. “The N-Safe mask is special as it has anti microbial properties and is washable upto 50 times,” said Dr Anusuya Roy, an IIT Delhi Alumnus and Founder and CEO of the startup, Nanosafe Solutions Pvt. Ltd. Roy pointed out that the triple layered mask has been certified from a National Accreditation Board for Testing and Calibration Laboratories (NABL) acredited lab with certification upto 99.2 per cent efficiency for bacterial filtration. “The mask is a triple layered one with a hydrophilic cotton inner layer followed by a middle antimicrobial layer and a final outer filtration layer that is oil and water repellent and designed to repel the virus,” said Professor Dr Mangala Joshi, Department of Textile and Fibre Engineering, IIT Delhi.
