Also protects against all chemical agents, acidic vapours and dust the label says, can be used up till 40 hours hence the hours in use ment to be written on it. Nice filter BTW.

Because it's a CO filter the times of use have to be written down on it. CO being colorless and odorless it's a very dangerous gas and as a user you would get no warning when the filter goes bad. That's why in modern times they rather use compressed air systems instead of filters.
