Hi I am hoping someone can help me with an idea of what it would cost to buy four gas masks and a minimum of extra filters for them? I have read and heard stories that some places sell only filters that are expired or do not fit certain masks unless they have an adapter. I am really trying to figure out what I would be looking at for a cost. What kind of masks does anyone on this site trust? I guess I should also think of four good hazmat suits as well? I just hate getting into the big ticket items. It depletes resources so fast. I have been working my tail off storing food (dry storage and canned), batteries, lamp oil, wicks, propane, canldes, water purification items, ammo, first aid items, etc, etc. I just keep having the feeling that I just don't have enough and I am having a hard time making myself make a jump to items that would take a lot of finances to buy. Anyway, any help would once again be appreciated. Also....the Wal Marts in my liberal minded, coddle me from the cradle to the grave state of Massachusetts do not even sell freakin lamp oil.
