Filter to adapt in 3M masks

Last crawled date: 5 years, 9 months ago

Because of the lacke of n95 masks in my city I thought of designing a stander particle filter that could be used in emergency cases in 6000 3M Masks. Thinking also in Wuhan people that are in quarentine and cannot go out for masks. Just playing with the idea. More designs will be uploaded.Feel free to redesign for your own necesities. Hope that can help.
