If a bathroom has no windows and doesn't get completely dry after a shower (neither do the towels, and the ceiling starts to grow black spots of mold), can a regular fan dry everything after the shower?
Which of these is more efficient? (forget about the other rooms that will get more humid)
- Placing the fan in the doorway, pointing to the outside the bathroom.
- Placing the fan in the doorway, pointing to the inside, oscillating.
- Placing the fan inside the bathroom, far from the doorway, pointing the doorway.
Why is the exhaust fan better than a direct wind into the surfaces? When we want to dry our hair, we point a blow dryer to it, and not a "humidity sucker".
Best Answer
You need a dehumidifier.

If there is no way to blow the humid air out, run it thru a dehumidifier. You can keep it in the bathroom running on a timer or roll it into the shower to run after you wash up, and let the collected water go down the drain.
