Instructions for assembly and use of 3D-printed masks

GRAND BLANC, MI – April 15, 2020 – The following are instructions for use and care of 3D-printed masks. For maximum respiratory protection, ensuring a proper seal against your face is important.

For Inital Fitting
  • Choose one of 3 sizes for best fit.
  • Shave facial hair (sorry Magnum, P.I.).
  • Put mask on then use a hair dryer to gently heat plastic and mold mask to face contours (focus on nose area and creating a good seal to face).
  • Apply weather-stripping, foam, or other gasket material along mask edge as needed.
Care
  • Remove front “window pane” and install new filter material at regular intervals based on usage and exposure.
  • Insert new filter and “window pane” from the outside and press firmly to ensure a tight seal.
  • Disinfect plastic every time take off face mask (wipe or spray).
  • Check elastic bands for tears or loose knots.
Suggestions
  • Try to minimize talking and smiling to maintain good seal to face.
User Notes
  • Emergency use device
  • Good samaritan masks, use at own risk
  • Your first line of defense: stay home
  • Your last line of defense: this mask
Filter Material
  • N95 masks
  • High quality, disposable, anti-allergen, HEPA Vacuum Bags
