Sharper Image Ionic Breeze® Quadra® SI837 Air Purifier

Pros: works, silent, can clean it yourself
Cons: $$$

So, I bought the Ionic Breeze Quadra Model # SI837 after a long milling and thinking over process. I had a Peaceful Breeze brand air purifier that I bought via Amazon.com for about $40 and it did not turn out as expected, so I did a little more research ...

Pros: Quiet, sleek looking, seems to be somewhat effective (but again keep realistic expectations)
Cons: Expensive, may not work as well as claimed by Sharper Image (see Consumer Reports)

***Please allow me to preface this by saying that a few years after I bought two of these Ionic Breeze Quadra GP units, Consumer Reports issued a review of them saying that they did not do much to clean the air. There is also research published on the ...

Pros: Silent air purifier, easy to clean. Visible proof it collects bad air.
Cons: Ozone odor stinks on this older model. Switch tends to give out prematurely.

The first one I bought worked great for about 10 months and the switch quit working, or something like a limit switch inside? It would not turn on. It was still under the three year warrentee, so I sent it back and Sharper Image sent me another unit, ...

Pros: Worked perfectly for years now. Completely silent. Complements my blower-filter machines by running 24/7.
Cons: They're certainly initially expensive - and how efficient are they, really?

I have a small office with 5 rooms and one of these running in four of them for 3 or 4 years now. I also used pleated furnace filters (merv-8, I think) and have traditional fan-blowing hepa filters that turn on by timers overnight 'cuz they're so loud. ...

Pros: Extremely quiet. Unless and until you clean the filter you won't even realize it's working!
Cons: None. If the price is too much then purchase a "like-new" model from Sharper-Image's outlet.

After reading the negative opinion by another reviewer I was compelled to write. I have both the Radio Shack Environizer and the Sharper Image Quadra Ionic Breeze. The Sharper Image product is far superior and contrary to what the other reviewer states, it most certainly does its job! I clean the filter weekly and am amazed by the particles the Ionic Breeze pulls out of the air. Because I have a range of allergies my house is generally dust free with the windows kept shut and no indoor smoking allowed. Yet the filter in the Ionic breeze is always coated with particles it has pulled out of the air. To think that these particles are still floating around amazes me. And just knowing that I would have been breathing in those particles if I didn't have the Ionic Breeze... need I say more?
