Not sure how familiar everyone may be with these things, so thought I'd share my experience. With the dehumidifiers I've used you also generally have two options for how they deal with the water they create (since they're literally pulling water out of the air, and a LOT of it depending on humidity.) One solution is a hose going directly from the dehumidifier to a drain (works best in a basement), and the other is to use the water container on the unit itself. With the unit container you have to be mindful of when the unit fills up, since at that point it should shut itself off until the water is poured out. I've neglected to empty mine for a couple days in the past and it doesn't seem to take long for humidity to rise from the 40% I like to keep it at up to the natural 60+% we get here in summer (at least for inside the house. Higher outside of course.) In the summer mine can fill up in just a few days of operation. I've been able to keep at a pretty constant 40% humidity year round, here in the northern Midwestern USA, using the hose to drain option. During the winter it's generally dry enough to not run at all.
