iLIVING 10-inch, 3-Speed Exhaust Fan with Thermostat

This fan form iLiving is slightly smaller than some others, which is perhaps what makes it a bit quieter. This smaller-sized fan offers quieter operation, but this fan comes in several large sizes to fit your needs. 

This perfectly satisfactory fan runs a bit less expensive than others and still remains on the quiet side. The built-in thermostat features 3-speeds and can regulate the temperature within a range of 32-130 °F. There is no controller for the thermostat, so you’ll likely need a ladder to adjust it.

Weather resistant shutters made of durable, high-grade aluminum are protected against moisture and corrosion.

 A 6-foot cord with standard 3-prong plug makes it easy to install, although you might need to add an extension cord to the mix.
