What is the small tube that screws on to the side of my gas mask for?

Responses (1)

well that is the FILTER of the gas mask
the whole process of cleaning the air is done by that filter
if you don't screw it on the gas mask is pretty much useless
also there is a plug on the mask and the filter be sure to remove both
before putting the filter on and using it

hope it helps

No. I'm not talking about the filter. There is a separate, smaller hole on the mask it's self that a small black hose can connect to. The small hose is about a foot and a half long and no air can move in or out.

oh you mean the hose
well it has some benefits compared to the filter it self
1-the hose let you to use a big filter canister instead of a small filter because with the hose connected you can attach the canister to your belt, so you will have more time before changeing it

2-because of the tendency of the gases to rise its better to have the filter lower than the mask so you use a hose

3-it makes the mask lighter and easier to move because a filter on the mask (or sometimes two) really gets in the way

hope it helps
