These low-noise ceiling-mount fans run quieter than regular whole-house fans while achieving the same performance. Their motor assemblies mount to rafters or joists high in the ceiling space and connect to a ceiling vent with a long, flexible duct. This configuration allows for optimal vent placement while reducing the interior noise level as compared to regular whole-house fans. Some units include high-efficiency electronically commutated motors and/or Bluetooth connectivity to provide efficient, on-demand cooling.

These roof-mount fans provide the benefits of a whole-house fan where the regular form factor would not fit. They install into the roof surface and connect to the living space directly or via ducting. When operating, they exhaust warm or humid air outside of the home and draw in fresh air through open windows and doors. They feature high-efficiency motors that uses less energy to operate than standard-efficiency motors.

These fans mount directly to a window frame and provide a whole-house ventilation solution. They are reversible to provide both intake and exhaust functionality. Some units feature specialized mounting brackets that allow the window to close behind the fan to seal out inclement weather and secure the structure.
