Filter to adapt in 3M masks

thingiverse

I'm designing a standalone particle filter that could serve as an emergency alternative to N95 masks, particularly in cities where they're scarce like mine. I'm also thinking of Wuhan residents under quarantine who may need access to face masks but are unable to leave their homes. This project is still in its infancy and more designs will be shared soon. Feel free to adapt or modify them as needed to suit your specific requirements, hopefully it can make a positive impact.
