Coronavirus COVID-19 mask

thingiverse

This model has not been certified by any regulatory agency. Use it at your own risk and only as a last resort if you have no other approved protection. The recommended steps to protect yourself from infection with the virus are unclear, and the mask structure (3 pieces) does not include the necessary filter to effectively block the spread of the virus. Additionally, further isolation measures may be required to properly fit the face without air gaps. Please check the comments for more information shared by other users about types of filters that could apply to a mask with these characteristics. The effectiveness of P3 particulate filters has been mentioned, and possibly also HEPA 12/13 filters, but unfortunately we do not have the means of analysis necessary to confirm this with certainty. Again, we remind you to use this model at your own risk.
