The present invention solves the problem of efficiently disinfecting and deodorizing indoor areas with ozone, without introducing health risks to people inside these areas. A cold plasma ozone generator generates ozone that is distributed to one or more rooms where disinfection and/or deodorization is needed. The distribution of ozone is regulated by valves controlled by a main control module collecting data from ozone concentration and IR motion detectors installed at rooms where the ozone is distributed, and other sensors in the ozone generator, and by using a schedule associating information derived from the sensory data, with dates, time slots, and desired ozone concentrations. If ozone concentrations exceed predefined levels, ozone generation and/or distribution is interrupted. When malfunctions occur, either the main control module commands the system to enter in emergency shutdown or lockdown, or a local control module or the ozone generator take control of the ozone generation and distribution.

An electro-ionic device configured for being worn on the face of a person is disclosed. The electro-ionic device includes at least two electrical conductors spaced apart from each other defining at least a portion of a respiratory pathway therebetween and a circuit configured to apply a first voltage between the two conductors during inspiration and a second voltage greater than the first voltage during expiration.

A sterilization and disinfection device includes a housing. A control board, a humidification water tank, a humidification water trough, an ultrasonic humidifier and an ozone water tank are provided inside the housing. The humidification water trough communicates with a humidification outlet through a humidification pipe. A humidification air input channel is connected to a humidification fan connected to a humidification air inlet. The ozone water tank is equipped with an electrolytic ozone generator. The ozone water tank communicates with an ozone gas outlet through an ozone gas output pipe and a mixing chamber. The ozone water tank communicates with a water filling port through a water filling pipe. An ozone fan is installed in an ozone air inlet. The control board is electrically connected to the button display panel, the ultrasonic humidifier, the electrolytic ozone generator, the ozone fan, the humidification fan and the power inlet, respectively.

The invention relates to devices for the treatment of air of at least one room. These are distinguished in particular by the fact that air which is low in bacteria, germs and odours can be provided in at least one room.

For this purpose, the device has at least one supply air line which supplies treated air and in each case has at least one air treatment device having at least one ionization module, an air flow sensor and an air humidity sensor. At least one exhaust air line has at least one air quality sensor. Furthermore, at least one dust-measuring device arranged in front of the ionization module and/or at least one dust-measuring device arranged in the exhaust-air line are present. In addition, the ionization module, the sensors and the dust measuring devices are connected to a data processing system for increasing or decreasing the ionization intensity. Furthermore, at least one device measuring the load current of the ionization module is connected to the data processing system, which assigns an operating state of the ionization module in the event of a load current change as a function of the measured values of the dust measuring device.

A transportable system for generating aqueous ozone solution includes a wheeled frame and an aqueous ozone solution supply unit that is coupled to the wheeled frame. The aqueous ozone solution supply unit is configured to produce an aqueous ozone solution onsite by generating and injecting ozone into water received from an onsite water source. The transportable system further includes an outer enclosure configured to surround at least a portion of the wheeled frame and configured to contain the aqueous ozone solution supply unit. The outer enclosure is also configured to store one or more external components for the aqueous ozone solution supply unit and one or more cleaning accessories when the aqueous ozone solution supply unit is being transported via the wheeled frame.

Systems and methods to treat an environment. The system includes a plurality of scent control material sources configured to output a scent control material (e.g., an oxidant) into the environment to reduce pathogens, dispose of scent molecules and their sources, and otherwise treat the environment. The system can include a controller communicatively coupled to the plurality of scent control material sources and cause one or more subsets of the plurality of scent control material sources to individually or collectively output scent control material into the environment.

A system for generating an aqueous ozone solution employs a mixing assembly disposed within an auxiliary compartment coupled to an external sidewall of an ozone supply unit enclosure. The mixing assembly includes a first flow path for water to flow through and a second flow path in parallel with the first flow path. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of the ozone supply unit enclosure. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path to produce an aqueous ozone solution.
