Air purifier and air purification method

An air purifier (100) and air purification method which comprises a processing unit (300) coupleable to a container (204). The processing unit receives air from the enclosed environment for processing such as purifying, ionizing and aromatizing. The processing unit comprises en impeller (308) for drawing ambient air into the processing unit, an ionizer (400) for ionizing the ambient air to obtain first processed air and a funnel (312) shaped for drawing liquid from the container and for substantially centrifugally expelling the liquid adjacent to the impeller for forming a liquid curtain (320). The impeller is for directing the first processed air trough the liquid curtain to obtain second processed air. The second processed air contains liquid molecules absorbed from the liquid curtain. The second processed air is subsequently exhausted into the atmosphere. The funnel is rotatable, conically shaped, whereby the narrow end is in contact with the liquid to be dispensed and the broad end distributes the liquid in order to generate a liquid film.
