If you are talking about something from say Lowes, we run one while on the boat along with the air conditioner. It makes it a lot more comfortable for sure and it doesn't take much run time to make a difference (hour or two). I like it because you don't have to freeze the place out to get rid of the humidity. However we fill the bucket every day. You'll have to find a way to drain it into a sink or shower. Many of them have the ability to run a hose out of them. I will warn you they aren't that small and are somewhat loud. Comfort is worth it though.
