SMF - Just Installed!
If you have worn a mask and glasses together for more than a quarter of a second, you are probably annoyed that we don’t have a magical solution for foggy lenses. Moisture-laden air is also a good indicator of where unfiltered air is escaping. Most masks have some flexible metal across the nose bridge that is supposed to seal the top, but it is woefully inadequate. The Badger Seal by [David Rothamer] and [Scott Sanders] from the University of Wisconsin-Madison College of Engineering is free to copy during the COVID-19 pandemic, even commercially. It works by running an elastic cord below the jaw and a formable wire over the nose to encourage contact all around both mouth and nose.https://hackaday.com/2020/09/02/fog-free-mask-hack-solves-mask-versus-glasses-conundrum-with-superb-seal/?fbclid=IwAR14pQTQ6b3vN4DL7xyThoFBhAOqB5px2YH1iUM-Hc8naydtnWU5DVQX6Zc
