Disclosed is a system for diffusing oil. In one embodiment, the disclosed system features an essential oil or aromatic substance diffuser, aroma pads, and a convenient packaging.

A magnetically attachable UV LED sanitizer system for indoor spaces having an outer shell assembly consisting of a rectangular cuboid outer machine shell, a front plate, and a back plate shaped in such a manner so as to fit inside an air conditioning duct register, diffuser or grille; a transparent cover, said cover allowing for the transmission of germicidal ultraviolet light frequencies; an ultraviolet lamp board; a motion detector capable of detecting movement of persons in an indoor space; at least one processor; a power supply; a rechargeable battery; a wireless network card; a magnet assembly capable of adhering the system to ferromagnetic surfaces such as air conditioning ducts, registers, diffusers and grilles. The system is programmable to emit germicidal ultraviolet radiation to sanitize air traveling to, from and through air conditioning ducts. The device is networkable with devices such as computers, smartphones and tablets.

A system and method for a mold and mycotoxin remediation system and method is provided. One embodiment serially accesses each one of a plurality of acoustic energy clips that are configured to kill a mold or eliminate a mycotoxin of interest, generates an acoustic energy content signal based on the acoustic energy information of the serially accessed plurality of acoustic energy clips, communicates the generated acoustic energy content signal to a speaker, wherein the speaker emits acoustic energy based on the communicated acoustic energy content signal such that the emitted acoustic energy kills mold or eliminates mycotoxins.

An ultraviolet air sanitizer apparatus for HVAC systems has a frame defining a flow passage therethrough configured such that the frame rear is insertable into a return air inlet of the HVAC system. A sanitizer light is disposed within the flow passage. When activated, the sanitizer light emits germicidal ultraviolet light into the surrounding flow passage. A light baffle is disposed within the flow passage upstream of the sanitizer light and allows air flow but blocks light. An air pressure sensing switch is electrically connected to the sanitizing light and configured to measure air pressure differential across an air filter. When the air pressure differential is a predetermined value or greater, which is indicative of air circulation by the HVAC system, the switch turns on the sanitizer light. When the pressure differential is less than the predetermined value, the switch turns off the sanitizer light.

A system, method and apparatus for disinfecting an indoor environment. The system includes a user computer having a user app and a controller operably coupled with the user computer remotely through the user app. The user computer is capable of communicating with the controller through a network. The system further includes a fixture for housing the controller. Within the fixture are at least one UV-C device operably coupled with the controller, at least one motion sensor operably coupled with the controller, at least one fan operably coupled with the controller, and at least one air filter coupled with the at least one fan. The system further includes at least one air quality sensor. The at least one UV-C device and the at least one fan are operable in a plurality of modes controlled remotely by a user via the user app.

An apparatus and method are provided for purifying air for breathing. The apparatus includes an armrest having a receiver and an air purification module releasably received in the receiver. The air purification module is portable and displaceable between a first operating position held in the receiver and a second operating position remote from the armrest and the vehicle.

An illumination device includes a first light-emitting module, a second light-emitting module and an airflow-guiding structure. The second light-emitting module is adjacent to the first light-emitting module. The airflow-guiding structure includes a receiving casing, a first air inlet pipe in air communication with the receiving casing, and a first air outlet pipe in air communication with the receiving casing. The first light-emitting module is received inside the airflow-guiding structure. When external air flows into the receiving casing through the first air inlet pipe by natural convection, the external air inside the receiving casing is sterilized by a sterilization light source provided by the first light-emitting module, and the external air that has been sterilized by the sterilization light source flows out of the receiving casing through the first air outlet pipe by natural convection, and is then discharged out of the illumination device.

The aroma providing device includes: an aromatic holding structure that is detachable and has a plurality of holding spaces in which aromatics are respectively held; a blower device that supplies air to pass through the holding spaces; a plurality of air supply paths through which the air is introduced into the respective holding spaces; an opening/closing mechanism that includes a member that is deformed by a physical stimulus or a chemical stimulus and switches whether to allow the air to pass through or not for each of the holding spaces; and a control unit that controls the opening/closing mechanism.

Provided herein is a system for disinfection and deactivation of contaminants, and more particularly to a self-contained compressed air disinfection system and method to deactivate pathogens on all surfaces and/or in the air of the targeted interior space comprising reusable compressed air cylinders and single-or multi dose containers of disinfectant or decontaminant.

Described are vehicles having viral inactivation and/or air filtration systems, kits and methods for retrofitting vehicles for viral inactivation and/or filtration of air within a passenger compartment of the vehicles, and methods for viral inactivation and/or filtration of air within passenger compartments of vehicles. The vehicles can be mass transit vehicles such as busses and the viral inactivation and/or filtration systems can include viral inactivation elements such as UV lamps and/or electrostatic filtration apparatuses mounted within a housing or frame mounted or mountable to a wall of the vehicles.
