Stay cool with this small and light evaporative air cooler from Sunpentown. This model comes on rollers and is very easy to move from room to room in your home or office. It also comes with a remote switch to make changing settings more convenient. This machine cools down your room endothermically, meaning it absorbs heat from air that it takes in. The Sunpentown SF-608R is not the same thing as an air conditioner, meaning it consumes much less energy.
