Described herein is a sanitization assembly including: a sanitization device, such as for example a photocatalytic device or ionizer or the like; and a containment element. The sanitization device is received in the containment element, and the containment element includes a box-shaped, box-like containment body. The box-like containment body includes side containment body surfaces and has dimensions in the width and thickness thereof that are substantially the same as those of a panel or rack or shelf of a furnishing element that includes side shelf surfaces. The box-like containment body can be assembled on the panel or rack or shelf, thus being continuous with the panel or rack or shelf. The side shelf surfaces substantially continue in the side containment body surfaces.

An ultraviolet (UV) germicidal irradiation system comprising: a light emitting diode (LED) disinfecting face mask comprising: a flexible mask body having a front surface and a back surface; a flexible printed circuitry (FPC) sheet disposed within the flexible mask body, the FPC sheet having a plurality of LEDs adapted to emit UV light, the plurality of LEDs facing the front surface; a vibration sensor electrically connected to the FPC sheet, the vibration sensor being adapted to detect vibrations; a UV-reflective layer disposed behind the FPC sheet, the UV-reflective layer being adapted to reflect the UV light; and a light diffusion layer disposed in front of the FPC sheet, the light diffusion layer being adapted to scatter the UV light; and a control module comprising: a central processing unit (CPU), an LED driver, and a power source; the CPU being in electrical communication with the LED driver and the vibration sensor.

A volatile material dispenser includes a base and a stand assembly that is coupled with the base. The base includes a fan and a battery therein. The stand assembly includes a platform, a stand that extends from the platform, and a manifold that extends from the stand. The volatile material dispenser also includes a shroud and an air deflector. The shroud is positioned on the base and defines a chimney. The air deflector is positioned between the shroud and the manifold. The air deflector is configured to direct air out of the chimney.

A method of inactivating one or more pathogens in an environment. The method includes providing light from at least one lighting element of a lighting device installed in the environment, the at least one lighting element configured to provide light toward a target area in the environment, the provided light having at least a pathogen-inactivating first component in a first range of wavelengths of 400 nanometers to 420 nanometers. The pathogen-inactivating first component of light produces an irradiance of at least 0.01 mW/cm.sup.2 as measured at a surface in the target area that is unshielded from the lighting device and located at a distance of 1.5 meters from an external-most luminous surface of the lighting device. Providing the light causes the one or more pathogens to be inactivated.

A flexible ion generator device that includes a dielectric layer having a first end, a second end, a first side, a second side, a top side, and a bottom side, at least one trace positioned on the dielectric layer and having a plurality of emitters engaged to the at least one trace. A plurality of lights disposed on the dielectric layer.

A lighting fixture is disclosed with effective disinfection properties against bacteria, fungi, and viruses. The fixture includes a fan to continuously draw air into the light fixture. The air drawn in is irradiated with UV radiation within the fixture, such as is provided from UV LED chips. The relatively small volume of the light fixture allows the flux or energy density of the UV radiation to be made more intense. After the air is sterilized, it can be put back into the room or building in which the fixture is placed. The white light provided by white light LEDs in the fixture provides illumination, and can further provide significant emission peaks at 405 nm and 470 nm which is also useful to pathogen inactivation.

A sanitization system for a space includes an ultraviolet (UV) light source configured to emit UV light towards a UV light zone at a UV light level, a motion sensor device configured to sense movements of one or more individuals, and a controller. The controller is configured to determine, based on the movements of the one or more individuals, an exposure parameter value for each of the one or more individuals in the UV light zone, determine that the value of the exposure parameter determined for at least one of the one or more individuals exceeds a threshold value, and, responsive to determining that the value of the exposure parameter determined for the at least one of the one or more individuals exceeds the threshold value, cause the UV light source to reduce the UV light level of the UV light emitted towards the UV light zone.

A germicide system for use in an air duct including a lamp, a lamp housing, and a control unit. The lamp housing is adapted to be positioned in an interior of the air duct and includes a lamp shield and quartz wool carried by the lamp shield. The lamp is carried by the lamp housing. The control unit is adapted to be positioned entirely in an exterior of the air duct and adapted to provide power to the lamp.

A sanitizing system for use in a laundry treating appliance and at least partially included in an agitator of the laundry treating appliance, the agitator may include a housing configured to be removably attached to a rotating drum or an impeller of laundry treating appliance, and an ultraviolet light disposed in the housing, wherein the ultraviolet light is configured to transmit ultraviolet light to articles of clothing disposed in a drum of the washing machine.

An air sanitization and purification system controlled by a thermostat in wired or wireless communication with an ultraviolet germicidal irradiation light or bipolar ionization appliance, with operation of the light or appliance controlled according to a pre-defined operation schedule of a heating, ventilation and cooling (HVAC) system or by receipt of sensor data indicating the presence of a person with an enclosed area heated or cooled by the HVAC system.
