CSIR-NCL’s Medical Grade Mask Enters Production

The technology for a superior face mask with better filtration efficiency than the available face masks in the market, developed by CSIR-National Chemical Laboratory (CSIR-NCL), Pune, was transferred to a Pune-based company SETLAB. The company has now started production of the mask.

CSIR-NCL’s patented bacterial nano-cellulose technology along with nano-coating was used in the mask. The cotton cloth coated in a solution of bacterial cellulose and nano-material completely prevents the penetration of bacterial growth. The Bacterial Filtration Efficiency (BFE) of CSIR-NCL mask is 99.9% and Particulate Filter Efficiency (PFE) is 92.63% PFE. This indicates a high restriction of hazardous particulates. The masks are made for easy breathability, are of medical grade and low flammability.
