A gas mask is a sealed mask which protects its wearer from inhaling hazardous gases, vapors, fumes, and particles. While wearing the mask, you have advantage against being poisoned or diseased from airborne sources, as well as resistance to the poison damage that they might cause. A gas mask is good for 24 hours of use; after that time, its Gas Mask Filter must be replaced in order for it to provide a benefit. A gas mask's filter(s) can be replaced with a Use an Object action. Some gas masks have one large filter, while others have two small ones, though they are functionally the same.
