Okay I give up. I have been everywhere in that bloody vault, and I can't find the HEPA 20 cartridge filters anywhere.

I have looked up vaultwiki, and even they could not help me.

Could anyone tell me how to find it from the elevator on the pest controll floor? I even found a set of lockers, but they where empty... There is nothing NOTHING left alive in there, but me and boone, and I can't take it much more.

Can't find the delete topic button... after 3 hours of searching I finaly found the buggering door. there better be something behind it for me to shoot, or I will kill Boone!
