Appropriate materials

What conditions should the materials fulfil? Which materials are recommended?

The best choice are certified or approved materials for medical applications. For masks that are not to be used in hospitals, suitable plastics with the following requirements are sufficient:

- transparent,

- scratch-resistent,

- non-fogging,

- not absorbing toxic fumes and

- easily disinfectable

The following table lists a few materials that are recommended:

*: Our open source publicated masks are not the final versions. There may be extensions / changes due to subsequent improvements. Our masks are currently not medically certified. We cannot assume any liability for the quality of the printed objects. So far there are only studies that suggest protection of others but not the wearer of the mask. The masks only protects if a filter material is inserted. How well the mask protects depends on the filter material and the fit. Please do not forget the other hygiene measures, this mask does not replace them.
