The present invention is generally related to an apparatus and method for sanitizing a continuous positive airway pressure (CPAP) device, in particular the invention relates to a system, method and device that attach to a CPAP device and sanitizes all of the parts of the CPAP device, including the inner areas of the hose, reservoir and face mask most prone for bacteria buildup. The device has an ozone operating system and one or more ozone distribution lines that distributes ozone to a CPAP device and a non-permeable bag for sanitizing a CPAP mask.

An air purifier (100) includes a housing (400) formed with an air duct (401), an ozone generation device (20), an activated carbon purification unit (80), and a fan (200) arranged in the air duct (401). The air duct (401) includes an air inlet (402) and an air outlet (403). The air outlet (403) is disposed indoors. The ozone generation device (20) and the activated carbon purification unit (80) are arranged in the air duct (401) along the direction of the air inlet to the air outlet (403), and the ozone generation device (20) is used to generate ozone. The fan (200) is used to suck gas from the air inlet (402) during operation and let the gas pass through the ozone generation device (20) and the activated carbon purification unit (80) to be discharged from the air outlet (403) into the room.

An apparatus and method for inactivation of airborne pathogens to include a reactor space with an intake opening, an exhaust opening, and an airflow path disposed between the intake and exhaust openings for air to continuously transit throughout the reactor space. The apparatus also includes at least one of (i) a corona discharge unit with a pressure swing adsorption unit, or (ii) a UV-C germicidal lamp to generate a sufficient concentration of ozone and UV light to inactive pathogens. The apparatus also includes a catalyst disposed within the path of the airflow to convert ozone to oxygen following the inactivation step and an adsorbent to remove nitrogen oxides from the air. The apparatus also includes sensors for measuring ozone and nitrogen oxides concentrations at the exhaust opening.

A sanitization apparatus for sanitizing the air in an environment is described as comprising a first filter which is arranged in an internal chamber upstream of a fan assembly, a second filter which is arranged in the internal chamber downstream of the fan assembly, a first ionizer device which is arranged in the internal chamber between the second filter and the outlet, a second ionizer device which is arranged in the internal chamber between the first filter and the second filter, an electronic control unit which controls the second ionizer device to sanitize the second filter.

An air pumping device providing automatic sterilization and pumping of indrawn air for oxygenation or other purpose comprises a shell with an air inlet hole and an air outlet hole, an electromagnetic assembly, a transmission device, an air pumping module, and a sterilizer element. The transmission device includes a swinging element forth for acting forces in two directions alternatively on the air pumping module, to draw in and pump out sterilized air. The air pumping device has two air pumping modules is also disclosed, the two air pumping modules being arranged symmetrically on either side of the swing element, therefore the swing element creates an indrawing of air and an exhausting of air for every swing.

A ceiling-mounted decontamination unit with one or more internal decontamination sources, which may be UV-C emitters, inside a housing with a hingable panel for access to the internal space of the housing for maintenance and repairs, and one or more fans inside the housing that re-circulate the air in a room and subject the air to the germicidal internal decontamination source inside the housing, decontaminating the air passing through the ceiling-mounted decontamination unit's internal space and destroying viruses, bacteria, and other pathogens. The ceiling-mounted decontamination unit draws the air in from the room or area where the ceiling-mounted unit is installed, subjects the air to the internal decontamination source destroying pathogens, and returns the decontaminated air back to the same room or area from which the air is drawn. An optional luminaire or external decontamination source may be attached to the room- or area-facing exterior of the ceiling-mounted decontamination unit.

An integrated system for sanitization and emergency lighting of rooms, comprising: - an external housing (23), which includes a white light source (13) with an optical system, apt to realize an emergency lighting, a battery (18) for operating said emergency lighting in the absence of a main power supply, - a chamber (19), provided with reflecting walls and internal lens shade baffles (16), in which a photo-catalytic reactor (20) and/or a UVC light source are housed, and - a fan (22), of axial or tangential type, which creates inside said chamber (19) a circulation or flow of forced air (F) taken from outside, upstream of said chamber (19) through inlet slots (17), and reintroduced outside, downstream of said chamber (19) through outlet slots (10), and - an electronic control circuit (14), which controls the operation of the white light source (13), the UVC light source and/or the photo-catalytic ballast (20), the battery (18) and the fan (22), characterized in that, inside said chamber (19), an ambient light sensor (11) is housed, aimed at measuring the brightness of the environment in which said system is positioned.

An ozonising module (1, 100) is disclosed having a housing (1a, 1b, 107) wherein an ozone generator assembly (3, 101) is accommodated, furthermore comprising at least an ozone sensor (4, 102) connected to a control unit (C) apt to control said ozone generator (3, 101) based on a time scheduling and a comparison between an ozone threshold concentration and a concentration signal from said ozone sensor (4, 102), ozone reduction means consisting of a filtering assembly with catalytic action (103) or a reducing assembly employing UV sources (113) through which an airflow is caused to flow by means of respective controlled ventilation means (103a).
