My dad just bought a Dehumidifier from Walmart, and it got me thinking... "Maybe THIS could fit in a Zombie Apocalypse!" After about five hours of being turned on, it already picked up around a quart of water, if not more, just from the air! He also told me that it's pure, but that one might be debatable in an apocalypse. The other awesome feat about it is that it barely makes any noise... almost like a simple fan being blown. Anyways, I just thought I'd shout that out. Sorry if it's not enough details to go by, but I kinda figured "Takes water out of the moisture of the air" could sound like something people would go for in a zombie apocalypse.
