Honeywell HF810 Mega Turbo Floor / Box Fan

This is one of the best fans I've found. It moves a lot of air and it's affordable, but most important to me is the fact it is very quiet on the low setting which is what I was looking for when I bought it. It's perfect for just enough white noise to cover up traffic and other types of noise, but not loud enough to be distracting. The only complaint I have is that it is hard to clean because it's necessary to take out several long screws before the grill can be removed. I would definitely recommend this fan to anyone.
