I have the Ecoquest Flair Air Purifier, I have had a machine since 1999. In the last few years I have moved several times and notice that regardless of where I live, the purifier leaves a black residue on walls and furniture in the same room as the purifier. It cleans off of countertops and appliances fairly easily, but walls must be repainted. It's quite annoying since I am renting and each time lose my security deposit because of it. I love my machine, it works great and my house always smells clean, but the black residue isn't! Can you offer any suggestions for why the machine would do this? (I clean my machine thoroughly every two weeks: fan blade, plates, insides, and oil the motor. I have replaced the fan motor once and replace the plates every year.)
Hi there,
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.

My air purifiers do the same thing. I have one in every room because my husband and children have asthma/allergies. I notice it's worse everytime I burn candles.
