Polluted indoor air is cleaned in three successive phases.
Phase 1: First, coarse dust and other polluting particles, such as human and animal hair and skin flakes, are captured in the prefilter.
Phase 2: The electrostatic main filter then removes the remaining smaller particles, from as small as 0.01 micron (= 0.00001mm!). The electrostatic filter works by means of a static (electric) charge. Particles with a like charge, positive or negative, repel each other while particles with an opposite charge attract each other. The polluted air first flows through the ionisation section, under a tension of more than 8 000 V. This imparts a positive charge to the polluting particles. It then passes the collector section where the pollution is deposited. The charged polluting particles are attracted by the earthed plates and adhere to them.
Phase 3: The activated carbon filter finally adsorbs the unpleasant odours.
The electrostatic air cleaner gives a much better performance.
