I have two quadra GP's and one day one just would not turn on and a week later the other just started to hiss. I have taken both apart and cleaned but neither is back to normal. The one still will not turn on and the other keeps hissing. Any ideas?
THE HISSING MEANS YOU EITHER STILL HAVE MOISTURE ON THE PLATES OR DID NOT CLEAN THE dust off it enough. try cleaning the plates one more time and make sure to not get too much moisture on them, dry off excess or air dry. the unit is hissing because of a short circuit caused by dust, hair or fuzz.
I have two Quadras not sure about the GPS. The only way to clean them properly is to complete the folowing steps. This will eliminate the hissing noises and intermittent shutdowns. Clean the blade unit as normal and leave it out of the unit. Unplug the unit, remove the four phillip screws on the top of the unit where the collector grid slides down. Next remove the four screws holding on to the base of the unit. After this you will see two additional screws also by the base that need to be removed. Look carefully between the grills of the unit and you will see about 12 to fifteen tiny screws that hold the grill together. After these are removed take off the UL label and seprate the grill. You may have to gently pull up on the top where the power switch is located. I have found if you use a lightly dampened scotch brite pad to carefully clean the two wires works best. Clean the wires and pins at the bottom and make sure all is well. Use a microfiber or lint free cloth to gently wipe everthing down and make sure the unit is dry. Put it back together and put the UL sticker back on.

The trouble began in 2003 when Consumer Reports magazine published a report claiming the expensive air cleaners don't clean air. The magazine later claimed its tests showed that Sharper Image's Ionic Breeze Quadra Silent Air Purifier and four other units also release potentially unhealthy levels of ozone.
Sparking, popping, hissing or crackling sounds coming from your Ionic Breeze air cleaner are all signals that it's time to clean your machine. Once you've cleaned the collection grids inside the Quadra, the disruptive sounds will disappear
how to clean
Turn off and unplug your Ionic Breeze Quadra.Grasp the horizontal handle on top of the air cleaning grids--this is in the very center top of your Ionic Breeze Quadra--and pull the grids straight up out of the casingWipe the metal grids down, inside and out along the entire length, with a clean damp cloth. You may need to use more than one cloth if the grids are very dirty.Go back over the grids with a clean dry cloth to remove any water and remaining dirtPut the grids aside on a clean, dry surface and grasp the body of the main Ionic Breeze casing unit in both hands.Flip the casing unit upside down, then right side up, five or six times. You should hear a small bead sliding back and forth as you do this. The bead is cleaning interior elements concealed in the casing; if you don't hear it, your unit may be in need of repair.Place the casing unit back on its base, orient the grids so that the handle slopes in the same direction as the top of the air purifier, then carefully slide them back down into the machine.
While the device is turned off and the filter is out, tip the unit itself upside down and back. Do this several times, there is a slider type cleaner inside that moves as you turn the unit. Be sure to do this every time you clean your filter and you will never hear a peep out of the thing.
1. Unplug the unit 2. Turn the unit upside down and listen for the beeds to move along the static wires from top to bottom. Turn it upside down again and again until you feel the static wires are cleaned of grime. 3. Plug it in again and see if the hissing is gone.
I have the same problem. The one thing that I DID notice is that it seems to occur more often in winter. Thus, I attributed it to dryer air conditions--too much static electricity being the culprit. With the unit off, I sprayed a fine mist of water into the housing and that cured it for a (albeit-short) time. Best solution would be to increase the humidity via a humidifier...
I have a sharper image ionic breeze hybrid gp that ran fine for years unitl it recently started sparking / arcing at the base of the grid blades and always in the same spot. I cleaned it several times but the sparking always came back and the unit went into either "drying grid" or "attention required" mode. The solution I found was to stand the removable grid in 2 inches of Pine-Sol cleaner 50/50 diluted with water for 24 hours then brush again with the cleaning brush and hot water. Presto! No more sparking.
