- Steamy mirrors in the bathroom?
- Fogged windows?
Seemingly minor annoyances often signal much deeper problems, such as;
- Mold
- Mildew
- Peeling paint
- Warping
- Ruined insulation
- Wood rot
- Toilet sweating
All of the aforementioned are symptoms of poor ventilation and you should consider installing a proper ventilation system, comprising an exhaust fan and ducting to the outside of your home.
Exhaust fans come in many noise levels, sizes, shapes and configurations. It is important that the ventilation system meets the needs of the square footage of the room that it is to ventilate.
Added features include lighting and heat lamps.
Timers can be added to ensure that the vent fan turns off after an appropriate period of time. Many people wire the vent fan to come on with the lighting in the room, ensuring that proper ventilation always takes place when the room is occupied.

Exhaust fans that are not ducted will not remove excess moisture, however they will remove room odors if they are equipped with a charcoal filter.
Note: Do not duct your ventilation system into an attic. This has the effect of adding a large amount of water vapor into the attic space which will ruin insulation and cause wood to rot.
