Very quiet fan

I am a physician and my exam rooms can get a little stuffy, even with the doors open. I have placed one of these fans in each of my exam rooms and they are great for keeping the air circulating. I have had patients sit 6-8 feet away from the fan and ask me where the breeze is coming from. That's how quiet this fan is, at least on low setting. By keeping the air circulating, the exam rooms are much more comfortble. I have since bought two more for use in other rooms in the office. This is a great fan that will quietly keep air circulating. If you're interested in getting a fan that makes you think you're in a wind tunnel, I'd check elsewhere.
