This is my THIRD one. At first I got the small one, but it did nothing, I spent $100 more for the large and the second one's red Clean light would not go off no matter how good I cleaned it. I took it back and now this one has the same problem witht the light, but also leaves dirt all over the walls and even my white computer! Aaargh!
Ok, makes me wonder why anyone would trust the Chinese to make a reliable product, but... try cleaning the contacts at the base of the blades with an
alcohol swab or pencil eraser; if they're the least bit dirty or have a
film on them, the contacts will not make up properly and the unit will
think it needs cleaning!

You bought that air purifier to help to clean the air in your home. However you have forgotten about it and now you expect it to still clean, when all of the cleaning surfaces and the filter that catches the big chunks are completely used up and covered with dust and dirt.
Here is what you need to do on a regular, like monthly, basis to keep it working well.
If your unit has a filter or pre-filter pull it out and wash it gently in some warm soapy water. If the filter is a throw away one then place it in a plastic bag and dispose of it. Be careful not to throw it away before you make sure you know what to get to replace it. You may need the old one for comparison when purchasing a new one. Also take note of how you removed it and the direction of the air flow. Some of the filters are made to have the air flow in a certain direction. The filter is often located in the back side at the bottom of the unit.
Take apart everything that you can on the air purifier and clean all the pieces with a moist cloth. You may need to take toothpick or something small to clean out the small grooves and crevices in the unit.
Leave everything dry completely before reassembling the unit. This may take quite a while for some of the filter media. A few hours is not uncommon, be patient.
You now will have your air purifier working in top condition again
I would use hot melt glue to hold everything in place. The air cleaner works by charging the air particle at the front and there is high voltage on the plates. The polarity of the plate alternates where the first plate is positive, the second is negative, the third is positive, forth is negative, etc .
With first wire in front charging the dust particle, the plate attract the charged dust particle to the plate to capture it.
We have Polywood Furniture that had grease from my son putting his bike chain on it while he was fixing his bike. I just took some mineral spirits with a rag and it wiped right off. Poly-wood is impervious to most all chemcials. I know www.polywood-furniture.com has a page that talks about how to clean your furniture. Still looks brand new!
Nothing, for at least 5 years, if you clean it regularly. Which means at minimum, of every thirty days. Especially the air intake filter on the back and the plaques and any dust build up you see inside the unit. A can of Compressed Air with a straw nozzle (like you clean your computer with) works well for cleaning the dust out.
About 5 years down the road, you will probably have to replace the plagues (also called plates).
When it comes to air purifiers, it's like Benjamin Franklin said, "Cleanliness is next to Godliness."
I had a similar problem with mine. It looked to me like the vanes were fluttering and causing arcing. I found an old piece of comb and slid the tines between the vanes to stabilize them. You might have to try it several times to get the position just right. So far its worked for me.
“white dust” is actually an indicator that your Electronic Air Cleaner
working properly. The Electronic Air Cleaner can only filter the
are passing through your system’s duct work. The staining particulate is
generally lighter, and more able to be drawn through the return
your home, leaving the heavier, non-staining particulate behind. This
non-staining particulate settles out of the air and is left behind on
furniture: because it is more visible, it may appear as though there is
actually more dust in your home than there was prior to installing the
cleaner. To ensure that more particulate is able to reach the Electronic
Cleaner to be filtered, you should make sure that the return registers
clean and not blocked by furniture.
The black residue is what is in your air. The reason for it to cling to the walls is the Ionization process that the machine creates. The ionization is to create a clean breathing space, free from contaminants. All particles floating in the air will be negatively charged and cling to each other or to objects in the room (like walls) that are positively charged.
If you cook, there is some smoke created, or when you burn candles. These greasy particles will stick to the wall or to surfaces. Cleaning them up regularly might help. You can also try another product from EcoQuest called EcoH which is based on enzymes and cut through that grime easily. That might take the black stuff off the walls.
A newly installed system should still be under the contractor's labor warranty. Call them and ask them to come out to check on the unit and explain what you wrote above. This should cost you nothing and is the best way to get to the bottom of the problem.
