At what % humidity should I set the dehumidifier for in a basement? Right now I have it at 45. Also, if the windows need to be kept closed at all times, when do I let in some fresh air? Our basement is getting warmer because the windows are closed. It was comfortable before, rather than the 73 degrees the humidifier shows. Do I also need to buy a fan or air conditioner?
I have the Danby premier from Costco.
