Provided is an air cleaner, and more specifically, to an air cleaner in which a filter part using a photocatalyst is formed in a module type to facilitate replacement and cleaning and which includes an insert fan which is disposed inward from a suction port of a casing forming an exterior and including the suction port disposed at one side and a discharge port disposed at the other side, and suctions ambient air, a driving motor provided to be axially detachably coupled to the insert fan in a direction from the discharge port, and a suction unit fixing part in which an accommodation space, into which the insert fan and the driving motor are fixedly inserted in the direction from the suction port toward the discharge port and which is finished by inserting a cover member in the direction from the discharge port.

A surgical smoke evacuation system includes a smoke evacuator, a suction instrument, a suction conduit, and a disinfecting device. The smoke evacuator includes a suction generator configured to create a vacuum force. The suction instrument is configured to couple to the smoke evacuator via the suction conduit. The disinfecting device is operably coupled to the suction conduit or the smoke evacuator. The disinfecting device includes a housing defining an inner chamber, an inlet extending from a distal end of the housing and in fluid communication with the inner chamber, an outlet extending from a proximal end of the housing and in fluid communication with the inner chamber, and an ultraviolet light emitting diode board. The ultraviolet light emitting diode board includes at least one ultraviolet-c light emitting diode disposed in the inner chamber and configured to disinfect surgical smoke within the inner chamber.

A device for disinfecting surfaces is provided. One embodiment has a plurality of UV light (energy) emitting LEDs residing in an enclosure, wherein emitted UV energy passes through a lens onto a surface being disinfected; a heat dissipator that receives heat generated by the UV emitting LEDs; and a fluid moving device. The enclosure has a fluid heating passageway that is in fluid contact with the heat dissipator, has a transfer passageway with a distal end that is fluidly coupled to a proximal end of the fluid heating passageway, and has a return passageway that is fluidly coupled to a proximal end of the transfer passageway and that is fluidly coupled to a distal end of the fluid heating passageway. During operation, the fluid moving device operates to circulate a cooling fluid through the fluid heating passageway, the transfer passageway, and the return passageway. Heat transfers to the ambient environment.

Method for increasing efficiency of a pathogen inactivation via enhancing UVC light absorption at such pathogen by multiple diffuse scattering of the light at a wall defining a substantially closed volume, thereby increasing a number of angles at which the pathogen is being irradiate as compared with a direct irradiation of the pathogen with a beam of such light.

A face mask is connected via a tube to a housing containing an ultraviolet (UV) light-emitting diode (LED) in a channel. A power source is connected to the UV LED. The channel is helical in shape and has undulations, so as to maximize the amount time the air is subjected to the UV radiation. The housing rear face has a fins to allow the heat from the LEDs to dissipate through the fins during use. This arrangement protects the user and others from excessive UV exposure and heat during use.

Disclosed herein is a diffuser air purification unit. The diffuser air purification unit can comprise a diffuser, a filtration chamber, a purification chamber, a blower, a housing, and a control module. The filtration chamber can be configured to receive air through the diffuser from an external setting in which the diffuser air purification unit is installed and to cause a filtration of the air when the air flows through the filtration chamber. The purification chamber can be configured to receive the air from the filtration chamber and to cause a purification of the air when the air flows through the purification chamber. The blower can be configured to intake the air from the external setting through the diffuser, the filtration chamber, and the purification chamber and to expel the air into the external setting. The housing can at least partially enclose the filtration chamber and the purification chamber. The control module can be secured to the housing and be configured to control an operation of the diffuser air purification unit.
