Air disinfection device using ozone for killing viruses, fungi and bacteria, as well as an ozone recombination unit

Air disinfection device using ozone for killing bacteria and viruses with an ozone recombination unit, comprising a housing (10), a fan (20) arranged in the housing (10) for forcing air to pass through the housing, an ozone generator (50) included in the housing (10) and arranged in a separate box (30) which is positioned across a path of the airflow, said ozone generator (50) is electrically driven by a supply unit (41) connecting a voltage to said ozone generator (50) to excite corona discharge, wherein a germicidal lamp (40) emitting UV-C light is arranged in said box (30), both the germicidal lamp (40) and the ozone generator (50) are driven by electric pulses having a frequency over 10 KHz, and an ozone recombination unit (60) is arranged behind the box (30) across the airflow passage to neutralize ozone included in the air flow that comprises at least two windings (63, 64) each having at least one surface comprised of respective spaced wires positioned across the airflow path and connected to another supply unit (61) coupling a pulsated voltage with a repetition frequency over 10 KHz between the windings (63, 64), wherein said voltage is smaller than required for generating a corona discharge but sufficiently high to force ozone to get recombined into oxygen.
