A portable air purifier may include an inlet configured to form a path along which air is suctioned, a filter disposed at an upper side of the inlet and configured to purify air which enters through the inlet and moves upward, a sanitizing portion disposed at a lower side of the filter, installed at a height allowing the sanitizing portion to overlap the inlet, and configured to irradiate sanitizing light toward the filter, and a fan module disposed at an upper side of the filter and configured to rotate a fan to blow air in a direction toward the upper side of the filter.

An air treatment system comprises an air conditioner; a bipolar ionization assembly; and a power supply. The air conditioner may portable and include a wheeled housing; an evaporator or entry grill for ambient air; a condenser grill for hot air discharge; a cold air supply discharge grate; a motor; an evaporator coil; and an evaporator blower intake. The bipolar ionization assembly includes electrical leads, and is mounted by a bracket to the evaporator blower intake to position the electrical leads within the air stream of the evaporator blower intake. The power supply is operably connected to the portable air conditioner and to the bipolar ionization assembly. When mounted in the air conditioner, the bipolar ionization assembly creates an antimicrobial plasma capable of killing harmful pathogens including bacteria, mycoplasma, viruses, mold and odors, and reducing the presence of Volatile Organic Compounds (VOC's), particulates, and static electricity in the air.

An air conditioner includes a suction panel including a suction grille that defines a suction port configured to receive air, an heat exchanger and a fan that are positioned within the case, and an ion generator disposed in the suction panel and configured to generate ions in the air received through the suction port. The suction panel defines an installation groove recessed from an upper surface of the suction panel and configured to receive the ion generator therein. The ion generator is accommodated inside the installation groove and configured to provide ions toward the upper surface of the suction panel in an upward direction that defines a preset angle with respect to the suction panel.
