I have got a question (I have an M65 Drager gas mask - I am not sure if it is original German made or not-) Can I use it against 3D printing resin
vapors?
The mask was left on a shelf for some years but it looks quite ok. and the Filter has not been used before -its seal is still intact- it has markings
on it which reads"Zivilschutzfilter 68 83/7227 and on the box that contained the filter there are "RM7970" and below it there is a
number "5940433" I can upload the photos of the filter if u like.
My questions:
1- Could this mask be used against organic vapors of 3D printers resins?
2- Knowing the fact that the filter was left for some years - intact- could it be expired?
3- on the internet I found some article that says these filters would last 8 hours on war field (against chemical warefars) how long will it last
against 3D printer resins?
