The Midea air cooler provides cooling similar to an air conditioner but with very low power consumption. It also provides air humidification and operates at a very low noise level. The unit's fan has 3 speeds and the cool air is distributed evenly through the room by oscillating vanes. Thanks to the rollers, the unit is very easy to move around. This air cooler is perfect when you need to move around a lot and best of all, it doesn't require venting like a portable air-conditioner.
