Types of Exhaust Fans for Retrofit

• Ceiling-mounted fans: Installed directly into the ceiling, these fans are ideal for bathrooms with limited wall space.
• Wall-mounted fans: Mounted on the wall, these fans are suitable for bathrooms with ample wall space and can be installed near the shower or bathtub.
• Inline fans: Installed in the ductwork, these fans are less visible and offer quieter operation.

Fan Size and Airflow Capacity

The fan size and airflow capacity determine the effectiveness of ventilation. Consider the bathroom size and layout when selecting the fan. A general rule of thumb is to choose a fan with an airflow capacity of at least 50 cubic feet per minute (CFM) for a small bathroom and up to 100 CFM for a larger bathroom.

Energy Efficiency and Noise Levels

Energy efficiency is important to minimize operating costs. Look for fans with Energy Star ratings or low wattage. Noise levels should also be considered, especially if the bathroom is frequently used. Fans with lower sone ratings produce less noise.
