nCoV is coming! But masks are running out!
Using a snorkeling mask, covered a small piece of mask on fan, ONE mask can be divided into 4-6 pieces.

The breathing resistance is still a bit large at the moment, I can't measure the resistance. But wearing it I can barely complete 40 squats.

12v runoff Fan = NMB 5020 BM5020-04W-B49 ( https://item.taobao.com/item.htm?id=553042177755 )
Power = 5v power bank + 5v-to-12v adapter ( https://detail.tmall.com/item.htm?id=526012870694 )
it even works for N95.

working in progress.
