Badger Shield+ Highlights:
[-] Meets the clinical needs of UW Health as a Class 1 face mask with a face shield but is not a respirator.
[-] Has gap on the sides that can be adjusted from open to mostly closed.
[-] Uses H100 Sequential Sterilization Wrap for its shroud. This fabric has comparable filtration characteristics to that of a high-quality 3-layer cloth mask based on preliminary tests by the UW-Madison College of Engineering.
[-] The shield was developed in partnership with UW-Madison College of Engineering, Midwest Prototyping, and UW Health, with the air assist component from Matrix Product Development.
Badger Shield+ Air Assist
Air Assist Highlights:
[-] A small blower fan, magnetically attached to the fabric of a Badger Shield+
[-] Powered by a light weight battery mounted to the head band.
[-] Circulates air against the inside of the shield for defogging while bringing in fresh air through the fabric around the chin. This makes the Badger Shield+ more comfortable to wear for longer periods of time by keeping the temperature around the face cooler as well as replacing expelled CO2.
[-] Was developed in partnership with Matrix Product Development, UW-Madison College of Engineering, Midwest Prototyping & UW Health.
