The Quilo Portable Air Conditioner is equipped with a self-evaporating exhaust hose. This means that moisture in the room is evaporated to the outdoors instead of accumulating inside the unit. On occasion, you can drain the unit, but it won’t need constant maintenance. In climates with acute humidity (think New Orleans), moisture will collect at a quicker pace than can be evaporated, and condensation will accumulate inside the unit—though it won’t be as much as a non-evaporating portable air conditioner. In this case, once the water tank is full, a full water tank alarm will beep and the air conditioning function will switch to fan.
