Apparatus for sedimentation and oxidation of fine dust and aerosols and organic loads such as viruses in a device, and for electrostatic and electrochemical or photochemical processesing of the air supplied by the device to a room for analog processes in the room

Air purification process with an antibacterial and/or antiviral air filter device for removing ultrafine aerosols and particles <2.5 μm and for inactivating bacterial or viral contaminants contained therein, wherein the air filter device comprises:

• at least one UV light device (1),
• an electrostatic precipitator (13),
• at least one ozone-generating UV light device (7) and
• an ionizer,
• wherein,
• an air stream to be cleaned is guidable through the air filter device, with the at least one UV light device (1) being arranged first in the direction of air flow between an inlet and an outlet for the air stream in the air filter device, which is equipped with at least one O3-destroying and with or without an antibacterial active wavelength,
• wherein downstream of the UV light device (1) the electrostatic precipitator (13) is arranged, which is designed to charge the aerosols, the particles and/or the organic contaminants in the ozone-free air flow and separate them on the electrostatic precipitator, and
• that downstream of the electrostatic precipitator (13) the ozone-generating UV light device (7) is provided, which is designed to emit a constant amount of ozone to the cleaned air,
• where the air purification process comprises:
• sucking air into a treatment device,
• removing ozone from the sucked-in air by UV radiation or catalysts and particles by the electrostatic precipitator and
• before the cleaned air leaves the treatment device, generating a proportion of ozone and/or ionized gas from the cleaned air.
