M-17 Gas Mask Filter Replacement: A Step-by-Step Guide

The M-17 is a type of military gas mask. It produces an airtight seal that protects the eyes, mouth and nose. The air breathed through the mask is filtered and cleaned so that any harmful gases in the air won't be inhaled. For this reason, it is important that the filters are well looked after and replaced if damaged.
