COVID19 - MASK - No support - universal filter media

thingiverse

I originally designed it to utilize coffee filters, but you can employ any medium that is accessible. It's advisable to seek out material used on N95 masks or air filters with a MERV rating between 13 and 16, as this will aid in capturing particles as small as 0.3 to 0.1 microns. If you can locate something more effective, please share it. Additionally, you can acquire inexpensive masks that don't fit properly or allow airflow through them and repurpose the material for this mask. The current design is suitable for an average adult and molds well. Scanning the model will enable you to print a customized version for smaller children or larger adults.
