Unit 8 mos. old and now makes loud, awful noise

How do I either get this unit repaired or replaced or is there something I can tweak to fix it?  It was always very quiet and hasn't been dropped or damaged in any way.

Mine is about the same age and has started doing the same thing. I knew it was a vibration from within, so cleaned all of the connections which did not help at all. The only thing that has helped is jamming cardboard down between the side walls of the unit and the HEPA filter. We have cleaned the HEPA filter several times thinking that was the issue. The vibration has not completely gone away, but is considerably better. The next time I clean it and redo the cardboard, I will put a piece on the top and bottom as well. Right now it only has about one inch by 6 inch strips on each side top and bottom, so 4 strips total. The noise is definitely vibration from the hepa filter and not the motor.

My Quadra Ionic Breeze, has a small glowing fire within it at the base. There is a smell of plastic/electric burn. Though the odor did cover the odors in my house, I think I have a fire hazzard on my...

the ionic breeze uses high voltage to move/filter air .. if the insulators break down there will be an arc such as what you see .. there is a way to dig out the carbonized material and seal it with materials that can handle the high voltage but any repairs are costly .. its unlikely you can repair it for less than a new conventional filter .. the ionic breeze was unique and expensive but didn't move a lot of air was quiet but often produced some ozone .. long exposure to ozone is not a good thing .. here is a site where you can learn more about your unit
check out where it says "Consumer Reports court case" ... that said, the electrostatic concept does probably remove small particles that are hard to do with conventional filters .. the arcing you see in your unit is indeed not safe . ... here is more that you likely don't want to hear..
in the next one look down where it says "Ionic breeze" under "helpful information" that will frost the cake
i am sorry to say that your expensive ionic breeze is not safe and not repairable.

i found a solution to the sparking problem in the ionic breeze. purchased scotch brite cleaning pads from home depot. using a long strip of pad scrub the plates back and forth especially in the areas that seem to be emitting sparks. i did this and the unit runs quiet as a whisper.

I have an Ionic Breese Quarda that just stopped working all of a sudden. Is there someone who can walk me through some basic fixes? Company out of business I'm told.

The high-voltage grid wire(s) most likely broke -- unfortunately, there is no good remedy for this -- I have repaired a half dozen of these units by replacing the grid wires with titanium wire. This is a very time-consuming, complicated, nerve-wracking repair -- not recommended. Even if the reapair is done, the unit will likely fail again, soon.

When my reapired units failed, I got units off E-Bay -- they didn't last very long either.

I'm now in the market for a more rugged ozone-generating air purifier.

on the bap1700 it is very quiet. i used to have one myself. sometimes you will feel the air and sometimes you won't all depends. if the fan is running than the unit is working properly. now if your hearing any noises or anything like that then there's a problem. but no to answer your question you didn't buy a lemon. if you have any other questions please let us know.

Is my Ionic Breeze Quadra hopelessly broken and beyond repair?

This unit can be replaced on ebay for around $45.00 which is under any labor cost to repair the unit you currently have. You can always post your unit for sale on ebay for parts.

Honeywell F 300 electronic air purifier

there's usually a troubleshooting guide stuck on the inside of the door.  it suggests a systematic flowchart for diagnosing the problem.
you should be able to isolate it to either the power supply (means replacement), or one of the cells.
on mine, one of the many little vanes got a bent during cleaning, and was shorting out.  (it doesn't take much.)  a quick visual and very little judiciously applied force straightened it out and fixed the problem.
i've also found that the unit will crackle a lot after a cleaning because of drops of water remaining in the cells, so i usually reassemble everything, but leave the unit turned off for an hour or two, which lets the blower on the furnace dry the cells for me.

Ionic breeze is arcing inside unit

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.

Red light won't stay off

I do apologize for the inconvenience, the best way that i can tell you to fix the light is that there is a tiny pin hole on top of the unit. that's a reset button. you need a small needle or something that will fit in there. hold it down for about 3 seconds. your unit should reset. the light sometimes comes on with new filters cause it hasn't recognized that they are new yet. if that reset doens't work please let me know
