The Vornado Portable Fan is an efficient way to cool a room in the summer and distribute heat in the winter. My Vronado table fan operates quietly enough that I can have it running at night. Point it forward and it sends a cooling, gentle breeze. Point it upward and it pulls down the heat in winter to more efficiently heat a room. Air Flow This fan is much cheaper than blameless fans but the airflow feels gentler than a regular fan Ease of Use Just plug it in, adjust the air flow, and that's it!
