I offer this for free for anyone to use and make a mask for themselves. I AM NOT a medical professional, but I am an award winning inventor, author, and teacher. N95 masks really should be in the hands of medical professionals during this Covid-19 pandemic. I had one from a long time before this crisis and wanted to backwards engineer one for myself and share with you my process. If you use the information here, please give me credit with a link to my blog www.artedguru.com or my publisher www.firehousepublications.com . Liking and subscribing will help me make more content for my students.
