We have a ranch on a finished walkout basement. The bank thoughtfully gifted us with 2 large (& expensive!) dehumidifiers when we bought the house. And by that, I mean the bank failed to remove them prior to closing! It has been hot and humid here in Southwest Michigan and I decided that I would turn on one of the dehumidifiers in the basement to help with the A/C. When I turned it on, it said that the basement had 80% humidity even though it didn't feel like it. The first couple of days, I emptied it about every 2-3 hours while awake. Now I only run it during the day and it stays consistently between 50-60% humidity and empty the reservoir before going to bed. It also has a hose that leads to a drain but haven't had that much water pulled from the air to need it.
