Is it true that the Arizer's vapor path touches electronics? What is in it that is bad?
It is true that the air path could be tidier, I don't think it has or will cause you any problems. Given the sheer number of these units out there, we would have heard if there were any medical complications.
The price is good for the features and style you get with the Extreme Q, making it a good value, but do check out others if in the market just to be certain. In the same price range is the Herbal Aire and for a little more you can get a Zephyr Ion.
All in all you just have to find out what is important to you, for me I couldn't bring myself to give money to a company that could have easily made a sealed air path, but for most the visual effect of the Arizer with the gadgets will bring it back in the running.
