How does Electrolux Air cleaner work?
A fan draws air in at the air cleaner´s lower edge, both front and back. First the air passes through a pre-filter. The largest dust particles are caught there. Then the air passes through an ionising unit where the particles are charged with positive ions. Then the air passes through the main filter, which consists of collector sheets of plastic-coated paper with positive and negative charge. A high voltage unit keeps the charge on the collector sheets constant. The electric field between the collector sheets causes the particles that were previously charged with positive ions to adhere to the negative collector sheets. The clean air flows upwards out of the air cleaner.
