  • Patent number: 9968809
    Abstract: Provided is a portable air purifier, which includes: a mask part; a first connecting hose having one end connected to the mask part; a second connection hose in which the first connection hose is installed, and at least part of which has an opening for introducing external air; an air purification module that purifies the introduced external air to a predetermined temperature condition and discharges the purified air to the first connecting hose; and a power supply unit configured to supply power to the heater. Since the air purification module for removing poisonous gases or biochemical pollutants through a catalytic reaction of a metal catalyst layer can be semi-permanently used, the conventional inconvenience of carrying an extra canister is removed.
