1. An air purifier comprising:
an air inlet portion through which polluted air flows in;
a plasma reaction portion connected to and in fluid communication with the air inlet portion and comprising a discharge region generating discharge plasma;
a gas-liquid mixing portion connected to and in fluid communication with the plasma reaction portion, and comprising a gas-liquid mixing portion housing, a droplet spraying device arranged in the gas-liquid mixing portion housing and including at least one spray nozzle spraying fine droplets, and a fluid mixing device which mixes the fine droplets with first purified air transferred from the plasma reaction portion; and
a gas-liquid contact portion connected to and in fluid communication with the gas-liquid mixing portion, defining micro-channels through which a gas-liquid mixture fluid transferred from the gas-liquid mixing portion passes, and including an impactor which captures droplets from the gas-liquid mixture fluid,
wherein the gas-liquid mixing portion and the gas-liquid contact portion are sequentially arranged in an opposite direction to a gravity direction,
wherein the air purifier further comprises a fluid communication portion extending in the gravity direction and arranged between the gas-liquid mixing portion and the gas-liquid contact portion, and
wherein the fluid communication portion comprises a vortex finder.
