Query: Mold issue

Just got off the phone with First Alert and asked them WHY my birth certificate and passport are now wrecked by mold.They told me that this is a known issue, and the reason you get condensation in the box is because it's so air tight that the moisture that's naturally contained in your paper documents has no place to go, so it turns to mold.Not sure if I buy this or not, but they said that in their new instruction manuals it states in big letters that you should air this thing out once a month. Mine isn't one of the newer ones, actually it's one of the "Honeywell" models and I don't remember reading anything about having to air my box out. Kind of crappy.They did get my address and are going to be sending out those silica bags to me free of charge. I guess they come in a pack of 6 and you can just call them up whenever you need some more and they'll send them out no questions asked.So I guess the customer service side is pretty good for a product that's sub par at best.
