What does the ionizer do?

Air Ionizers send molecular particles into the room which clean the air. The ions attach to oxygen in the air and create a negative charge. Once it becomes a negative ion it attaches itself todust,smoke,odour andpollen and creates acluster. This clusteristhenpulled back by the ionizer and captured within the filter. All De'Longhi air purifiers include an ionizer and a washable pre filter.
