Engineers at the University of Wisconsin-Madison are innovating face masks to keep people safer during the coronavirus pandemic.
The researchers came up with the Badger Seal Mask Fitter. It’s an adjustable frame that fits over the outer seal of a three-ply disposable face mask and is supposed to keep more particles from spreading to others. The team is currently sharing how to make a Badger Seal, which they say costs less than one-dollar to assemble, on their website.
