I have mine in my tent. Dehumidifying your room would require a nice size dehuey. I tried running mine in the room and it didn’t really do much. Once I put it in the tent it changed everything dramatically. See the attachment for the model I have. It has the ability to set the desired level of dehumidification which is extremely helpful. I don’t use the hose because the reservoir doesn’t exactly fill up that fast, but in the event it does, the machine has an auto shut off feature if it’s full. You will notice when it’s not working because your humidity will shoot through the roof at night. I also have a hygrometer that really doesn’t serve a purpose in terms of reducing humidity because the machine does it on its own, but it does help with kicking in my humidifier when needed.
