This unit does not have any kind of a drain hose for outside drainage. I am gone for extended amount time in the summer so I cannot run it when not there to keep cool and and the humidity low. We got this unit to relace another LG unit which was defective after a few months. The same unit was on their  website but unavailable and had to get something else. Couldn't speak to anyone to get a comparable model. Very disappointed with the overall experience with LG
