This unit is amazing for yanking dust and such out of the air and making it go away. I'm not inclined to complain about the noise it makes, because the only way this thing can live up to its claim of being able to recirculate the air in a large room 6 times per hour is to move a *lot* of air, over a *large* space, and do it *fast*. Outside of a ceiling fan (which is a lot bigger) there is simply no other way to do it than with a blower that you're going to hear.
One reviewer said it sounded like a floor blower (or something like that). Well, it blows at an upward diagonal, but in terms of air volume it may come close. It has to, to get the whole room to circulate back to the unit and get sucked in. Want your room's air cleaned for *real*? Grab one of these. I used a Honeywell 13500 for over 10 years before it finally died and the 50250 took its place. No regrets.
This product does a great job sucking dust out of the air and is easy to maintain. It is big, but not that heavy. I saw that people were complaining about the sound, so let me say this: it is about as loud as an air-conditioner in fan mode. It helps me sleep because it is a constant relaxing sound. It blocks out other sounds coming from other rooms/outside that aren't constant or relaxing.
If you've got the space, I recommend this product.
