An HVAC air freshener comprises a cylindrical housing having at least one opening in the wall of the housing along the length of the housing, the housing adapted to be inserted through an opening in a planar portion of an HVAC plenum or ductwork, a fastener encircling and attached to the housing near one end of the housing and adapted to attach to an exterior planar surface of the plenum or ductwork, and a fragrance cartridge inserted into the housing. The fragrance from the fragrance cartridge escapes from the cartridge through the housing opening and into the plenum or ductwork.

Embodiments disclosed herein relate to air flow control blinds or tents useful for controlling scents emitted therefrom. The air flow control blinds can include walls, a roof, windows in the walls, and at least one directional vent disposed on the walls, where the at least one directional vent includes an inlet on the inner surface of the blind and an outlet fluidly connected to the inlet, the outlet facing downward on the outer surface of the blind to direct fluids flowing therethrough towards the ground. The air flow control blinds may include one or more roof vents adjacent to the walls on the roof. The air flow control blind includes at least one oxidant generator mount on one or more of the roof or the walls to mount an oxidant generator thereon. Blind systems can include a portable oxidant generator positioned in the blind.

An air-conditioning system has a filter slot in which a replaceable filter can be held. An air-treatment device in the air-conditioning system can be introduced into the filter slot through a service opening of same provided in an inlet region of the filter slot and can be mounted and fixed on at least one edge delimiting the service opening of the filter slot.

An air treatment device includes: a casing having an inlet through which air is drawn, and an outlet out of which the air drawn through the inlet is blown; a blade configured to adjust a direction of the air blown out of the outlet; and a generator configured to generate an antimicrobial element that sanitizes the blade. The blade has a first surface, and a second surface opposite to the first surface. The blade is shiftable between a first position in which the antimicrobial element is provided to the first surface and a second position in which the antimicrobial element is provided to the second surface.

The Desktop Air Purifier with Double-layer Glass Tube Ultraviolet Disinfection Lamp (The desktop air purifier with DLGTUVDL) uses a turbo blower with an air filter to draw in outside air to be disinfected through its specially designed double-layer glass tube ultraviolet disinfection lamp. The ultraviolet disinfection lamp of the desktop air purifier has a double-layer glass tube with an inner glass tube and an outer glass tube. The center of the inner glass tube is a hollow space for external air to pass through and receive UV disinfection. This unique design allows ultraviolet rays to surround the entire hollow tube space to provide 360-degree ultraviolet radiation and disinfection at a close distance without dead ends, which greatly improves the disinfection efficiency. In addition, the desktop air purifier with DLGTUVDL has the function of natural plant scent air purifying agent to provide the disinfected air that carries the natural plant scents.
