Animal litter boxes are provided which include a sensor to detect a change in an environment within an interior of its housing and an odor removal device (ORD) operationally connected to the sensor such that the ORD is activated in response to a signal from the sensor. In some cases, the ORD is configured to operate in different manners based on respectively different signals from the sensor. In addition or alternatively, the litter boxes may include a timer configured with the sensor for activating and periodically reactivating the ORD at preset time intervals in response to a sensor signal. In yet other embodiments, the litter boxes may additionally or alternatively include a timer having user adjustable settings of different time periods at which to initiate activation of the ORD and/or user adjustable settings of different durations at which to operate the ORD, both in response from a sensor signal.

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).
