| 1. An air purification device comprising:
a discharge device for generating a streamer discharge between a discharge electrode and a counter electrode facing the discharge
electrode;
an electric power supply for applying voltages to both the electrodes; and
an air blower for distributing to the discharge device a stream of air to be treated, the air purification device being capable
of decomposing, by the streamer discharge, a component to be treated which is contained in the air stream to be treated;
an air volume control part for switching the air volume of the air blower among a plurality of set air volume levels; and
a discharge control part configured to switch the discharge electric power of the discharge device to one of a plurality of
set discharge electric power levels depending on the air volume level set in the air blower.
