Gill™ Mask is the first product developed under Gill™ Lab, founded in Singapore by partners Jean-Luc Fringeli, Veronica Chew, Cheong Siah Chong, Lim Eng Seng and Ken S K Chuang.  During the COVID-19 surgical mask shortage primarily affecting Asian countries in early 2020, medical suppliers were rushing to find or produce more surgical masks.  The Gill™ team decided to tackle the problem from a different angle to reduce surgical mask consumption and offer a more protective seal. 


Inspired by snorkeling masks and the ability to breathe under water, the team used their expertise in designing medical devices and user experience to develop a safe, comfortable and sustainable respirator suitable for both professionals and the public.
