There are other brands that make quality quiet fans. My Vornado runs 24x7 and on minimal setting is inaudible, on second setting is very quiet. And it costs way less than a Dyson! I have two units in the house, and when I ordered second unit I got a defective one - probably fan was not balanced. It was making noise like normal fan. I exchanged it on Amazon, and boom - second quiet fan in the house.
