If that dehumidifier really removes 50 pints per day, just realize that you will either need to install a drain hose, a condensate pump or potentially empty it 3+ times/day.
(see 1.8 gal. tank capacity)
Also, be aware that dehumidifiers work much like modified air conditioners and throw out a good bit of heat in the process (eg- increase your AC demand).
They are not very efficient electrically, even the high efficiency/energy star models.
You may get a little surprise when your power bill comes.
