 Runs full time, pretty quiet., 2007-04-08
We've got dark brown wood floors, and it seems that the place was showing dust pretty much after 2 days, since the dust was light, and the floor was dark. We see less dust now, and according to my spouse, my snoring is apparently not as window-rattling as it was. I can't say that this cleaner is to credit, though...could also be the time of year and my diet changes.
My wife was really worried about noise...we'd had some panasonic filters before, which were relatively quiet, but we're now running this one full-time on position 3 out of 4, and really don't notice the sound at all. In fact, on all but the max power of this system, it's very quiet...And I wouldn't consider running this on max except under extraordinary conditions.
This unit is sorta big, but we've got it behind a chair, so that you really can't see it from anywhere but next to that chair.
It doesn't have as many features as some others, like sensors to determine when to increase airflow, etc, but really, is that a useful feature or a geeky one?
It coulda got more stars from me if it was cheaper or more compact, but I may buy another (smaller) one for the bedroom as well.

 Does what I expected, 2007-01-03
It's been on since I opened it up about 4 months ago for the twins. Max setting is a bit loud but then again it has to move a lot of air so I can't imagine it being any less quiet. Anything below max is rather quiet. Wish it had some type of sensor or the ability to dim that blue active on light it has. But other then that it's really a simple box. It has a fan in the middle, 3 filters and just goes and goes. Almost feel like the fan should be reversed and the filters too. It draws air from below and filters within so I'd imagine the insides will get very dirty at some point. You'll know what I mean when you get it.

Too expensive, degrades over time, 2006-02-17
I bought this from all the hype from consumer reports (This is the 501 model, not the 401). At first it seemed to get rid of 95% of pollutants (dust, etc) in the room at which it was placed... after a long while, it dropped to 80% or so. After I replaced the filter, it went back up to 90 to 95%... I found out that the outgoing (or is it incoming) vents actually get dirty with dust and have to be cleaned ocassionally to maximize the effect and efficiency of the device. Who knows if the internal components also get dusty degrading the device as well (I suspect that it does to some extent, even if the particles are small). Too bad there was nothing about that in the instruction manual. The cost of replacing filters gets too expensive in the long run in my opinion. True, it has helped with breathing, caughing, etc..., but next time I think I'll just get me something akin to the models that allow you to clean the filters without actually buying them - even if they aren't as good. I can buy 2 of them with the money saved in the long run instead of just one of these units. It might not be as effective - but in the big picture of things, if you don't have allergies, then it really doesn't make sense to get this. And if you do - you probably need something more expensive anyway. About the only real plus I can say is that this thing really looks good and is much better than ozone generators that I've used to clean air in the past and at least it does work to some extent (unlike products that are in my opinion waste of money - like most ozone generators that are used to clean air).
