DMC assisted the Seguro team with the electronics and product development for a Covid-19 air filtration face shield. Users wear the device on their head. The face shield uses a high efficiency HEPA air filter to remove viruses from the air surrounding the user, providing them with a steady stream of clean air. It is safer and more comfortable to wear than traditional face masks — while also providing the added safety barrier of a clear face shield.


DMC engineers worked closely with the Seguro team to develop an electronic Covid-19 face-shield through researching, conducting experiments, and evaluating features to refine the product design specifications. Based on this information, DMC developed a proof-of-concept electronics package for evaluating prototypes.

Next, DMC began work on the production electronics. Engineers made improvements to the device’s fan speed control and battery management to maximize runtime. A custom PCB was designed to fit seamlessly into the design envelope.

The Airsafe Face Shield can run for several hours using a custom lithium battery pack with quick charge capabilities. The resulting product is safer and allows the user to breathe naturally while maintaining better protection than traditional masks.
