Sharper Image Ionic Breeze - Air Purifier - Professional Plus Review

The Sharper Image Ionic Breeze is suppose to purify the air by using static electricity to attract dust to the metal rods located inside the casing.  I have a few pets and a family member that's allergic to pet dander.  So, rather than getting rid of the pets and/or the family member I decided to try the "Breeze" instead.  I bought 3 of these things and placed them strategically around the house and guess what!  Not much happened.  Somehow I expected a little more hustle for the price.

These things have to be cleaned once a week and there is evidence that some dust, smoke, dirt etc. is being picked up.  However, all things considered, I expected a little more muscle.  I'm sure I could have gotten another purifier that would do at least as well and for half the price.
