Had a couple people voice their concerns over Gas Masks becoming too much of a tool to the point they aren't worth keeping even as a PID item. This seems to be solidified with the fact that players are stuck gasping for air when the mask/mask filter reaches 0%, forcing the wearer to remove the mask and find a new one.
While I understand the concept, I can see that someone who has always worn a Gas Mask in DayZ purely for the aesthetic are now penalized by listening to their character struggle for air "permanently".
