I've been busy with my 3D printer getting masks made for those in need. Please let me know if you need or want one. I can make 2 to 6 a day. If you want to donate to the cause message me, but these are free of charge for those that need something in these crazy times.
So as you see Gen 1 worked, but needed improvements. I did add a shield to stop direct particles from hitting the filter of choice, after doing some more tests we moved to the next 1.
Well it works better and its anti-bacterial so improvements moving along
