This is more than just a fan. Not only does it move your cool air around in summer but is also a heater. Do you have a room or older person in your home that needs a little warmth without turning on the main heat. This can focus on just the person or the whole room. It has select air flow. Dyson is truly a awesome fan. It has a thermostat to set the temperature, remotely controlled. If knotted over it will turn off. Safe around kids and pets.
