A plasma purification module is described. The plasma purification module includes a first electrode plate, a second electrode plate, at least one long electrode and a catchment element. The first electrode plate is configured to be connected to a first electrode of a power supply. The second electrode plate is disposed over a surface of the first electrode plate, and is configured to be connected to a second electrode of the power supply, in which the second electrode plate has a channel. The long electrode is configured to form a discharge area. The long electrode is disposed on the surface of the first electrode plate and passes through the channel. The long electrode has a tip. The catchment element is disposed adjacent to the tip, and is configured to provide the discharge area with mist or water.

The present invention relates to an air conditioner including a dust collecting filter assembly for collecting foreign substance from the air sucked in through an inlet. The dust collecting filter assembly includes a high-voltage electrode film, a ground electrode films alternately disposed to face the high-voltage electrode film, a separator film disposed between the high-voltage electrode film and the grounding electrode film so that the high-voltage electrode film and the grounding electrode film are spaced apart by a predetermined interval, and a fastening part to fasten the high-voltage electrode film, the ground electrode film, and the separator film together and integrate them. With this configuration, it is possible to simplify the manufacturing process of the dust collecting filter assembly provided in the air conditioner, minimize the distance between the high-voltage electrode film and the ground electrode film, and improve the dust collection performance by improving a dust collection area by the separator film.

An air decontamination device (100) comprising: an input unit (102); an output unit (103); and a decontamination unit (104) coupled at a first end (122) to the input unit (102) and coupled at a second end (124) to the output unit (103). The decontamination unit (104) comprises: pairs of conducting plates (108), where one conducting plate of each pair is for being positively charged and the other conducting plate of each pair is for being negatively charged. The positively charged plate and negatively charged plate are separated to form an airflow path (212) and a 3D material (110) that is capable of being potentiated by static electric field is coupled to each side of conducting plate (108). When the static electric filed is applied, the surface moieties of the 3D material (110) are realigned to a direction of the static electric field to potentiate the antimicrobial activity of the 3D material (110) for destroying the microbes present in the received air.
