Effective little bugger
I received this plug-in filter as a gift, but having had it for a little over 8 months I would happily buy another. I love the convenience of it. It feels comfortable and well made in the hand, about the width of a pop can. It's pretty tall, though not enough to be overbalanced in a properly fitted outlet; if it does get top-heavy, there's a swivel on the back of the unit that allows it to be turned to the left, right, up or down which can sometimes help stability - or just free up space in the outlet.<br /><br />And of course, it works. I noticed a big improvement in the air quality of my bedroom. Granted, this isn't a very big purifier: it's strong for it's size, but I wouldn't recommend using it for anything larger than your standard bedroom's size. It's also a bit noisy, but it's a steady sound that I found unobtrusive and quickly got used to - very much a white noise.
