Designed in Singapore, the Gill Mask is a timely homegrown innovation in face of a global shortage of face masks due to the COVID-19 pandemic.
Gill™ is the first product developed under mas™.
It was developed in Singapore to address the COVID-19 surgical mask shortage that was affecting Asian countries in early 2020.
When everyone was rushing to find or produce more surgical masks, we simply took the problem from a different angle, and focused on reducing the surgical mask consumption and offer better sealing.
Mdesign team used their expertise in designing medical devices, user experience and snorkeling masks to develop this product.
