The design community was quick to rise to the challenge of helping the world overcome the Coronavirus, but this came at a cost. Human consumption of plastic tripled in 2020 with the use of surgical face-masks, so designer Ollie Butt decided to combat both the virus and the trail of plastic trash the pandemic left behind. Ollie’s Face Mask (although conceptual) paves the way forward for an aesthetic, efficient, reusable gas mask that can actively filter air coming from the outside, while continuously measuring the quality of the air inside the mask. Equipped with a circuit board on the inside and a bunch of sensors (including one for sensing humidity), and an outward-facing LED strip, the Reusable Face Mask looks and feels cutting-edge. The LED strip plays a dual role, adding a futuristic flair to the device while also allowing the mask to tell you when to change your filters. The humidity sensor on the inside can detect when the filters need replacing, and a simple plug-in-plug-out design detail lets you swap out old filters for new ones. The reusable mask comes with a silicone seal around the mouth, allowing it to fit comfortably while creating a tight seal, and around-the-head straps ensure you can wear the mask for long hours without worrying about ear-fatigue.
