as far as I know there are very tiny screws along the sides of the unit. 4-6 screws. remove and make sure to safely put them somewhere and not loose them. good luck.

I have the same problem as gerardperez7. One of my germicidal light quadras won't turn the light on and doesn't appear to be cleaning the air at all. I even put a new light bulb in it and it doesn't fix the problem.

Turn uoside down a few times

Oh there are a lot of known issues! I used to work for sharper image and I believed in this items very much so until mine broke. However after a year I figured out how to fix it. Take the big square collection grid out and the back screen off. Now get you a thick rag and be very careful because there are several tiny wires going up and down. Smaller than dental floss, you need to be very careful because you can either brake them or slice your finger wide open( Under any circumstances I can not be held liable for the information I am giving you try this at your own risk). Now with the towel very gently go up and down each wire like you are polishing a brass pole(once again these wires are thin and can break or cut you). Do this from the back side of the unit and from the inside where the collection grid that you took out sits. Take your time and be thorough, and presto your 400 dollar air cleaner is working again.

Could be a blade replacement needed but Sharper Image recalled the product.  Since it was proven in court that it wasn't effectively cleaning the air by Consumer Reports as well as EPA data.  As a result of the legal action, Sharper Image filed for Chapter 11.
Here are a few links about it:

If the warranty you are counting on is a Sharper Image Warranty I need to advise you that it was voided in the buyout on 30 May, 2008 when everything at Sharper Image was liquidated by Hilco Consumer Capital, Gordon Brothers, and Bluestar Alliance. If however it was a warranty company outside of Sharper Image you need to contact them.

You can purchase a bulb for the GP on ebay for under $11, which is really a good price considering what you would have paid from Sharper Image. Installation is easy, you just pull up on the tab on the bottom of the filter and pull up. When you are looking at the bulb, turn it 1/4 turn, (2 clicks) and pull it out. That is all there is to it. Hope this helps you.

Ionic Breeze machines are no longer being supported. Sharper Image recalled the product several months ago after it was proven by Consumer Reports and the EPA that the product wasn't cleaning the air and can be harmful to use. Sharper Image took legal action and lost.

The Consumer Product Safety Comission is going to make a decision on all ionizers by the end of the year. It's looking like all ionizers will no longer be sold in the U.S. regardless of who makes them.
