How much water does a dehumidifier extract from a house per day?
Have you had the dehumidifier enclosed in the bathroom with the windows and door shut. A dehumidifier will extract moister from everywhere so it’s hard to answer your question. I’m in the hire industry and rent these machines out all the time to plasterer’s to dry out rooms but you have to make sure to keep it enclosed and also to only use electric fires to help dry out because a gas fire puts 70% moister back into the room.
