Air purifier device

An air purifier device comprising:

• at least one first collector comprising:
• a non-insulating material first surface of size greater than 1 m2,
• a non-insulating material first reference surface, and
• a first electric generator configured to apply to the first surface a first potential relative to the first reference surface between 5 kV and 500 kV so as to generate an electric field between the first surface and the first reference surface greater than or equal to 10 kV/m;
• an ionizing device configured to ionize some of the fine particles present in the air;
• an agglomeration chamber configured to aggregate at least some of the fine particles ionized by the ionizing device into aggregates of fine particles,
• wherein the at least one first collector is configured to collect at least some of the aggregates of fine particles;
• and
• a frame configured to enclose at least the ionizing device, the agglomeration chamber and the at least one first collector,
• wherein the ionizing device comprises a plurality of spikes, a grating and an electric generator configured to apply to the spikes of the plurality of spikes a predetermined potential relative to the grating so as to generate an electric field of at least 100 kV/m between the plurality of spikes and the grating.
