Swiss biotech company Livinguard ® developed a textile for reusable masks that inactivates bacteria, fungi, and viruses (including Covid 19) upon impact. This idea is brought to life in the packaging: The mask comes in a sterile package. An attached plastic strip animates – when slid up and down – a virus that is getting eaten in the process, adding some urgently needed humor in desperate days. To avoid the mix up of masks among family members, and hence cross-contamination, differently colored adjustment clips come in a separate sleeve to customize each mask.
