Transparent Mask

Flawa Consumer GmbH

Flawa Consumer GmbH is an expert in the development and production of absorbent cotton products, respiratory masks as well as innovative fresh shoe soles. With a successful company history of over 100 years, they act as a competent and reliable partner for numerous Swiss, European and American retailers.

Since the beginning of the pandemic, hearing impaired people have been confronted with an additional difficulty: Due to the mandatory use of masks, they can no longer lip-read and therefore hardly understand anything. Flawa and QUO developed a partially transparent mask where the lips are visible.

Rapid implementation of prototypes

QUO AG’s challenge was to set up a rapid and iterative product development process to provide the mask as quickly as possible to the public.
To this end we implemented and tested initial designs at a very early stage in our in-house workshop. With these prototypes, we were able to gather feedback directly from those affected, which was then incorporated into the further development of the mask. The many iterations in a short time resulted in an industrializable prototype that exceeds the requirements of the FOPH and meets the medical Type II standard.

The mouth window, which exposes facial expressions, enables lip reading and eliminates communication problems. The innovative anti-fog coating on the inside of the mask prevents fogging of the transparent film. The partially transparent mask fits as good as the standard masks and the shape of the window is inspired by a smiling mouth which leaves a positive impression.

The partially transparent mask of Type II is available on the market after only two months of development. It can be ordered under the following link (german): Medizinische Gesichtsmaske Transparent Typ II MaXsmile 105079 25er Karton – Flawaconsumer Shop (
