An air purification system for use in a given location to remove or destroy harmful pathogens in the air. The air purification system has a housing with an inlet, an outlet, and a passageway extending between the inlet and the outlet. An intense field generator and filter is used to charge any particles in the air and remove them from the air flow. Finally, a dielectric barrier discharge unit having a high voltage electrode coupled to a dielectric barrier and a ground electrode spaced apart from the high voltage electrode is used to form a low temperature plasma chamber is in communication with the passageway so that the ions created in the plasma chamber will attach to and destroy any remaining particles in the air flow.

Breathing treatment device (100) for therapeutic use, the device comprises a motorized air recirculation system, a set of filters for air purification (10a, 10b, 10c, 10d), an ultraviolet ray sterilizer and an plasma electrostimulator, the device characterized in that it comprises means for the ejection of air in laminar flow (6) with noise emission between 0 and 5 dB; means for redirecting the laminar flow towards the head of the patient, a stabilizer (1), a multifilament diffuser (2), one or more UV-C LEDs (11).

A system and method to both reduce interior levels of volatile organic compounds and carbon dioxide that is more energy efficient than increasing building ventilation rates. The system comprises a carbon dioxide scrubber that operates in a continuous manner, and optionally but preferably further comprises an air purifier.

In order to guarantee reliable maintenance, a reliable energy supply and simple handling of the service cover and the vehicle air conditioner at the smallest possible structural cost, it is proposed that the service cover has electrical means, by means of which an air-treatment device arranged within the vehicle air conditioner can be supplied with the electrical energy necessary in order to operate said air-treatment device from outside the vehicle air conditioner.

A light system includes a main body defining an internal chamber and a lighting assembly secured to the main body, wherein the lighting assembly comprises at least one light unit configured to emit light. The light system further includes a fan configured to generate an airflow and an airflow circuit configured to direct the airflow out of the main body of the lighting assembly. The light system also includes a tilt detection unit configured to detect a tilt angle of the lighting assembly and to generate a control signal to cause a speed of the airflow generated by the fan to change based at least on a detected change in the tilt angle of the lighting assembly.

Apparatus, methods and instructions for disinfecting air. The apparatus may include, and the methods may involve, a fixture. The fixture may include a germicidal light source. The fixture may include a fan. The fan may circulate air through a volume into which the germicidal light source propagates germicidal light. The light source may be configured to emit, upward from a horizontal plane, a beam that, absent reflection off an environmental object, does not cross the horizontal plane. The apparatus may include a shield that prevents light from the light source from crossing the horizontal plane. The sensor may face upward from the horizontal plane. The sensor may face downward from the horizontal plane.
