Title: An effective device
Review: The Hamilton Beach 04163 works well in all respects, is more aesthetic than many other purifiers on the market, is reasonably quiet on low speed, and is a great value. I have mind in my bedroom. If I even slightly shake my comforter, the purifier's sensor quickly detects the dust fibers that are released. I checked the carbon filter after about 2 weeks of nightly use and could easily see on the filter where the purifier had trapped a great deal of larger dust particles and fibers. My only criticisms are that the purifier does not "remember" the UV light on/off state. So if I turn on the UV light, then turn off the purifier, when I turn on the purifier again, the UV light will not longer be on. I endorse this product.
Is the review positive or negative?
