There is provided an EFEM, including: at least one load port; a housing closed by connecting the at least one load port to an opening provided on a side wall of the housing and configured to define, in the housing, a transfer chamber for transferring a substrate; a substrate transfer device disposed in the transfer chamber and configured to transfer the substrate; an inert gas supply unit configured to supply an inert gas to the transfer chamber; and a gas discharge unit configured to discharge a gas in the transfer chamber, wherein the at least one load port includes: an opening/closing mechanism capable of opening and closing a lid of a mounted FOUP; and an accommodation chamber kept in communication with the transfer chamber and configured to accommodate a part of the opening/closing mechanism.

The present disclosure relates to a portable air purifier. The portable air purifier includes: a fan case having a narrow width portion at the front thereof and a wide width portion at the rear thereof, the narrow width portion including a space the radiuswise width of which is less than the radiuswise width of the wide width portion, and a fan blade protruding centrifugally further than the space formed inside the narrow width portion while being disposed at the wide width portion.

Provided is a cooking apparatus including: a main body; and a ventilator comprising a ventilator body including an inlet configured to inhale air containing oil mist generated in a cooking process using a heating device, a blower configured to blow the inhaled air from the inlet; and an oil mist filter positioned inside the ventilator body, and configured to remove the oil mist by filtering the oil mist from the inhaled air.

An air filtration system is disclosed. The system comprises an air conduit having an inlet and an outlet, a self-contained electric power source, an electrically powered fan, an air filter located transversely across said air conduit, and an air boundary containment nozzle at the outlet of the air conduit. The nozzle has an outlet diameter of between about 0.5 centimeters and about 4 centimeters. The nozzle minimizes the mixing of the unfiltered ambient air with the filtered air directed to the wearer.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

Provided is a humidifier comprising a housing including a suction port and a discharge port; a water container having an opening/closing valve; a water tank unit provided with a water tank, a humidifying member, a blower unit for providing air-blowing force, a water feed adjusting member installed on the water tank unit, a water feed operating member for moving the water feed adjusting member, and a controller for controlling an operation of the water feed operating member. The water feed adjusting member includes a space forming member having an opening, the opening guiding the water discharged from an outlet of the opening/closing valve to the water tank unit, and the space forming member includes a confinement space that may confine the water discharged from the outlet when the housing is inclined at a certain angle or greater.

A cleaner comprises a housing having a dust collection chamber formed in the housing and configured to open and close, a main body movable relative to the housing between a first position whereby the main body closes the dust collection chamber and a second position whereby the main body opens the dust collection chamber, and a motor filter mountable to and demountable from the main body, wherein the main body includes a fan motor unit to generate a suction force, and a shutter device mountable into the main body and configured to open and close a flow path between the motor filter and the fan motor unit.

An air filter essentially for use in woodworking workplaces includes a casing having a top panel, a bottom panel, two sidewalls, a filter gauze, a motor, and whizzer blades. The casing has an inlet anteriorly and an outlet. The casing has therein an inner blocking wall which extends rearward to form two inner sidewalls. The two inner sidewalls are each penetrated by a through hole. The two through holes face each other. The casing further has a curved panel bending in its thickness direction. The curved panel and the two inner sidewalls together define a receiving space. The curved panel curves to an extent corresponding in curvature to part of the outer edges of the whizzer blades and is spaced apart from the whizzer blades by a predetermined distance.

Various embodiments of the present invention disclosed herein relate to an air cleaner, and may suck outside air and purify and sterilize the outside air, and may perform sterilization of a filter. An embodiment of the invention disclosed herein discloses an air cleaner including a body forming an appearance; a suction unit formed on the body and introduced with outside air; a discharge unit formed on the body and discharging the air introduced through the suction unit; a fan module provided inside the body and forming a flow of air introduced into the suction unit and discharged to the discharge unit; a filter unit provided inside the body to filter the air introduced into the suction unit; and a light source unit provided inside the body and irradiating light toward an inner side surface of the filter unit.

A hand vacuum cleaner has an openable air treatment stage. The air treatment stage has a lower openable portion that is moveably mounted to a forward portion of the pre-motor filter housing.
