Enjoy flexible, energy-saving cooling with the Emerson Quiet Kool portable air conditioner.

Convenient features include a remote control, 24-hour on/off timer, and sleep mode. A washable and reusable easy-access filter is a great way to keep the unit running efficiently and alerts you when it's time to clean.
