It's becoming a hassle to refill water bottles and whatnot at the dining commons, so I want to get a water filter. Which do you guys recommend? Brita, PUR, other...? Pitcher, or larger (I've seen up to 2 gallon, but how easy are those to fill from your average faucet?)? Faucet-mounted (probably not a good idea for a dorm anyway)?. I want to spend as little as possible, and I don't want to have to worry about maintenence (replacing a filter once a month I can deal with, though).
