Query: Extremely noisy!

There are 3 fan settings on it and the lowest setting is ok as far as noise goes. To get really clean air though, the other 2 settings are ridiculously noisy. I can't hear anyone talking to me or even use my TV unless it's turned up to #45 on volume! It's in my home office where I usually watch TV. After awhile, I start to get a headache due to the fan noise and it causes me to leave the room. I wish I bought something else. Do I want really clean air and can I put up with the noise? hmmm....not sure. UPDATE: After using it 3 more weeks, I've decided I can't put up with the noise (or headaches) any longer! Not worth the postage cost to return it so I'm donating it to Disabled AmVets. I hope someone plugs it in before taking it home. It has no rattles and I know this is the usual sound it makes. Deserves less than 1 star!!!
