For Inital Fitting

- Apply weather-stripping, foam, or other gasket material along mask edge as needed.
- 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.
- Try to minimize talking and smiling to maintain good seal to face.
- Emergency use device
- Good samaritan masks, use at own risk
