Holmes HAP1200-U LifeLong HEPA-Type Tower Air Purifier

The previous reviews of this product are pretty accurate.

The issue of the rattling fan is true (I have proven to myself that it is the fan - my first guess is the use of sleeve instead of ball bearings, and the fan may be a bit underpowered to draw the air through the HEPA filters). Right out of the box it didn't have the rattling sound, but after just about 10 hours of running, there it was. Because of this, I would agree that putting it right in a bedroom would not be the thing to do. I don't have it right in the bedroom, and I do have a white noise generator on the headboard, so I don't notice that little rattling noise at night; and during the day it makes no difference to me anyway since I can't really hear it unless I am within about 10 feet of the unit.

I bought this as a fan for when I sleep. I wanted a product with HEPA filter, and this model was very attractive because its filters never need replacing. Overall it seems like a good product.

I can still sleep with the low and medium speeds, though.

I've worked with this product in one of my work environments and I love it. Though I can't tell you I can see the difference in the air, I notice my allergies are not acting up anymore in this work environment. I'd say the product is doing what it was designed to do and for what it's worth I'd say it is a great investment.
