Noisy, but you get used to it, and it does help
I keep this in our poorly ventilated bathroom to help air it out after use, and I do believe it genuinely helps.<br /><br />The downsides are three fold.  First, if you're sensitive to noises, stay clear of this or prepare to get used to it.  I can hear it two rooms away when it's plugged in. I hated it for the first two weeks, then only sort of hated it, and eventually got used to it.  I know I'm more sensitive to noise than most, though, so it may not bother you.<br /><br />Second, the vents on the machine will clog frequently with dust and they are not easy to clean.  I found a solution that works for me though - I use a doctor's toothpick and clean the vents with the frilly end.  It works very well, and you know it's time to clean it when it's quiet enough that it doesn't bother you.<br /><br />And third. I've had it just shy of a year and today the motor is making a constant &#34;worn out&#34; whine, so I think it's time to replace it.  Not too bad for a whole year, but a shame I'll need a new one.
