WHAT IS THE “BLACK WALL” EFFECT?
Electrical discharges in good ionisers produce large amounts of negative ions. These negative ions bind the positive charged particulates of the air (dust, soot, etc.), agglutinate these small particulates to larger one, which become heavier than the air and fall to the ground or are collected onto so-called DDCs (double dust collectors) inside the AIRBUTLER ionisers. In order to reduce this “black wall” effect, we use double dust collectors. DDCs are easy to clean and long-lasting. No expenses to remplace the filter! If you notice a little bit more dust than usual around your ioniser, it’s a positive sign. It’s better to vacuum or wipe the dust than to inhale it.
