Choosing A Ceiling Exhaust Fan

When choosing a ceiling exhaust fan, use the following to help you: Calculating the area of the room you wish to install the ceiling exhaust fan (Length x Width x Height). Then multiply this number by the number of air changes required (approximately 10 for a standalone toilet and 15 or 25 for a shower). This will give you the approximate capacity (or airflow) required to ventilate the room. Please check out the exhaust fan calculator page for more information. Does the ceiling exhaust need to be ducted? If it is replacing an existing fan, what hole cut-out size does it need to fit? Once you have this information, use the interactive options on the left hand side to narrow your search to find your ceiling exhaust fan solution. Back to all exhaust fans.
