Residential and office fans circulate air to replace stale air with fresh air, or to cool people or animals. Office and residential fans are used in smaller spaces than industrial fans, including offices, homes, and garages. Freestanding fans, such as floor, table, and pedestal fans, have a base so they can be placed on a floor or table, allowing them to be moved as needed. Mounted fans, including wall and window-mount fans, are permanently installed. Wall-mount fans can be mounted at any height to direct air flow where it's needed. Window fans are installed in a window frame to bring fresh, outdoor air inside.
