A clothes treatment apparatus comprises: a cabinet forming a treatment space for storing clothes; a filter module having a filter portion for filtering out dust from air passing therethrough; an air flow path having a plurality of preset flow paths for directing air to be discharged into the treatment space; a fan for moving the air in the air flow path; at least one valve disposed on the air flow path; a valve actuating module for actuating the valve; and a control part for controlling the valve actuating module so as to select one of the plurality of flow paths. The plurality of flow paths comprise: at least one bypass flow path for directing the air to bypass the filter portion; and at least one filtering flow path for directing the air to pass through the filter portion.

The invention relates to a filter for filtering particles from a plasma plume. The filter includes a housing with two pass-through openings arranged in the housing wall and forming a pass-through channel for passing at least part of the plasma plume through the housing, which pass-through channel extends from one side of the housing to an opposite side of the housing, at least one primary blade arranged at a distance from and rotatable around a rotation axis, which rotation axis is parallel and spaced apart from the center line of the pass-through channel, with the path of the at least one primary blade intersecting with the pass-through channel and with the at least one primary blade having a contact surface for contact with the plasma plume, which contact surface is facing in the direction of the rotation direction, and a drain channel connecting to a drain opening arranged in the housing wall. A line extending perpendicular from both the center line of the pass-through channel and a radial line extending from the rotation axis through the center line of the pass-through channel and through the path of the at least one primary blade, extends through the drain opening.

An air purifying system may include a main air purifier placed in an indoor space, a handheld air purifier mounted on the main air purifier, and an air quality sensor IOT device that communicates with the main air purifier. The air quality sensor IOT device may be fixed in an outdoor space adjacent to the indoor space, or may be carried by a user to measure air quality data while the user travels. The main air purifier may automatically operate based on air quality data received from the air quality sensor IOT device.

A high elongated portable air-conditioner is disclosed. The air-conditioner comprises a compressor, a condenser, and an evaporator located inside a housing. The air conditioner further comprises a cool air inlet and outlet and a warm air inlet and outlet. The air-conditioner has an axial evaporator fan and a radial condenser fan and the housing of the air-conditioner has an elongated shape where the end sections of the elongated air conditioner housing forms a top section and a bottom section, respectively. Other features of a portable air-conditioner are also disclosed.

The present disclosure relates to a removable filter system for removably coupling a filter unit to an air supply unit provided in a boiler. The filter unit is detachably coupled to the air supply unit, so that after removing the contaminated filter unit coupled to the air supply unit, a new filter unit can be coupled to the air supply unit or the existing filter unit can be reused after removing contaminants remaining in the filter.

The present invention discloses an air purifier, including: an air intake structure and an air discharge structure. The air intake structure is connected and fixed to the air discharge structure via a quick-release structure, the air intake structure is provided with a filter screen, and placement/removal of the filter screen is enabled through engagement/disengagement of the quick-release structure. The air purifier of the present invention has a simple structure and a rational design. The air purifier is divided into two parts, namely an air discharge structure and an air intake structure which are arranged one above the other, and quick dismounting and mounting of the upper part and the lower part are enabled by means of the quick-release structure, thereby realizing quick and easy replacement of the filter screen, and effectively improving the replacement efficiency. In addition, the air purifier has a simple and attractive appearance.

An air purifying system may include a main air purifier that has a flat upper surface configured to support at least two cylindrical portable air purifiers. Each of the main and portable air purifiers may have a fan to suction air and a filter to filter suctioned air. The upper surface of the main air purifier may include a seating groove, an elastic member provided in the seating groove, and a seating plate resting on top of the elastic member. When a portable air purifier is seated on the seating groove, the elastic member may be compressed and the seating plate may be lowered such that the portable air purifier may be supported within an inner wall of the seating groove. When the portable air purifier is removed from the seating groove, the elastic member may expand and raise the seating plate back to an initial position.

A handheld air purifier may include a suction body provided with a fan to suction air and a filter to filter foreign matter from the sucked air, a handle extending from the suction body, and an agitator provided in the suction body to loosen or scatter dust from a garment. The handheld air purifier may be configured to be attached to and detached from a main air purifier, and the main air purifier may suction dust off the handheld air purifier and sterilize the handheld air purifier when the handheld air purifier is mounted on the main air purifier. The agitator of the handheld air purifier may have a striking member exposed through a lower surface of the suction body, and may move out of and into the suction body to strike the garment so that the dust may be loosened and suctioned into the suction body and filtered by the filter.
