convert old masks to n95 masks?
RE: convert old masks to n95 masks?
There is another filter on some coffee makers that looked interesting. It is an inline activated charcoal unit for the water tank. My Krupp machine has one. It would most likely have to use a hose.

I would think that too much chemical liquid applied to one of the disposable N95s could cause degradation of the filtering material as well.

Yes, using liquids degrades the mask function. But you can bake in an oven as described in the linked paper - but, as you note, one wrong move and you are infected, which is why I think trying to put a lining into a full face CPAP mask is problematic. You can't get it safely out easily without cross contamination.

I'm no expert, but believe N95 masks have to cover the eyes - which some people say are a major point of viral entry.

I have started on new thread on converting CPAP masks that cover the mouth and nose into a somewhat more normal CPAP mask:

Oops, I'm wrong. N95 masks are often used along-side eye protection, but I seem some being sold that don't have eye protection built in.
