Abstract: An ionizing device is described, comprising a tubular bulb made of electrically insulating or dielectric material extending along a longitudinal reference axis and having the two longitudinal open ends and opposite each other, a tubular cathode engaged in the bulb, a tubular anode fitted to the bulb, a pair of covers, each of which has a respective internal seat into which a respective end of the bulb is inserted so as to hermetically seal it, and a conductive electrode which extends into the bulb and is electrically connected to the cathode.

Abstract: A sanitization apparatus for sanitizing the air in an environment is described as comprising a first filter which is arranged in an internal chamber upstream of a fan assembly, a second filter which is arranged in the internal chamber downstream of the fan assembly, a first ionizer device which is arranged in the internal chamber between the second filter and the outlet, a second ionizer device which is arranged in the internal chamber between the first filter and the second filter, an electronic control unit which controls the second ionizer device to sanitize the second filter.

Abstract: An ionising device is described comprising a tubular bulb of electrically insulating or dielectric material extending along a longitudinal reference axis and having the two opposite longitudinal terminal ends and open, a tubular cathode engaged in the bulb, a tubular anode fitted onto the bulb, a pair of covers coupled to a relative end of said bulb so as to hermetically close it, and a conductive electrode comprising a stem extending into said bulb, and a plurality of conductive crowns which are fitted onto the stem at predetermined distances from each other and are suitable to exert an elastic compression on the tubular cathode against the inner surface of the bulb.
