Abstract: An operation mode of an air cleaner is changed according to the degree of indoor air contamination and an indoor space condition, and one or more filters of the air cleaner can be easily cleaned. The air cleaner includes a housing, an inlet located at a lower part of the housing, a filter assembly, an outlet, and a brush unit. The filter assembly is located above the inlet, and a diameter of the filter assembly is gradually shortened in the direction from an upper part of the filter assembly to a lower part of the filter assembly. The discharge port is located above a second filter assembly. The brush unit is used to eliminate contaminants from an outer surface of the filter assembly.

Abstract: A filter module and an air purifier according to an aspect of the present disclosure include a supply roller and a recovery roller, a filter wound and installed on the supply roller and the recovery roller, so that it can be used without replacing and cleaning the filter module for a long period of time by allowing a section used in the filter to be recovered in the recovery roller, and also a section not used in the filter to be supplied from the supply roller.

Abstract: A cleaner including a cleaning module capable of easily removing foreign matters such as hair entangled in a brush unit is provided. The cleaner includes a main body including a suction port, a brush unit rotatably provided at the suction port, and a cleaning module detachably received in the main body and configured to remove a foreign matter entangled in the brush unit. The cleaning module includes a housing detachably received in the main body, a cartridge provided in the housing to be movable in a vertical direction, and a cutting unit provided at a lower portion of the cartridge and configured to cut the foreign matter entangled in the brush unit.

Abstract: An air purifier is provided. The air purifier according to an exemplary embodiment includes a body including an air inlet and an air outlet, an air blowing unit disposed in an inside of the body, the air blowing unit being configured to forcibly introduce outside air into the inside of the body through the air inlet and discharge air into the air outlet, a filter unit rotatably disposed between the air blowing unit and the air inlet, a driving motor configured to rotate the filter unit, and a cleaning member detachably connected to a vacuum cleaner and disposed in proximity to the filter unit to guide contaminants adhering to the filter unit to be flown into the vacuum cleaner.

Abstract: A ventilation system and a method for discharging hazardous air during cooking are disclosed. The ventilation system allows hazardous air generated by cooking to flow in a backward direction of a cooking device so as to quickly transfer the hazardous air to a hood, such that the hazardous air is prevented from being inhaled by a user. As a result, the hazardous air may be concentrated into a predetermined region without being dissipated, and then subsequently discharged outside. Information about a quality of air generated in a current state of a cooking space is transferred to a user so that the user may more actively use the ventilation system, thereby better protecting the user's health.
