1. Exhaust Fans: Exhaust fans are the most common and efficient option for bathroom ventilation. They work by extracting moisture and steam out of the bathroom and expelling it outside through a duct system.
2. Window Fans: Window fans can be installed in a bathroom window to draw in fresh air and push out stale air. They are less efficient than exhaust fans but can still provide some airflow.
3. Passive Ventilation: Passive ventilation options include installing vents in the ceiling or walls, which allow air to flow in and out of the bathroom. These options are not as efficient as exhaust fans, but can be helpful in smaller bathrooms with limited space.
4. Heat Recovery Ventilators (HRVs): HRVs are high-tech options that use a heat exchanger to capture heat from the outgoing air, and use it to heat up the incoming air. These systems are efficient and can be used year-round.
5. Humidity-Sensing Fans: Humidity-sensing fans automatically turn on when the humidity in the bathroom reaches a certain level, and turn off when the humidity drops again. This can help keep the bathroom dry and prevent mold and mildew growth.
