An HVAC decontamination system with regulated ozone output based on monitored ozone level in ambient air is disclosed. The HVAC decontamination system includes an ozone supply unit and an air analyzer. Based on one or more control signals from the air analyzer, the ozone supply unit is configured to: (i) generate ozone when an amount of ozone per unit volume of air is less than a predetermined threshold; and (ii) cease to generate ozone when the amount of ozone per unit volume of air exceeds the predetermined threshold.

An electronic apparatus capable of air pollution reduction includes an operating tool and an airflow device. The airflow device is located adjacent to the operating tool, and has a shell with one or more opening holes distributed thereon for air to flow in or out.

A solid-state electronic dehumidifier (SSED) to improve the performance, productivity and longevity of small-scale ozone-generating devices. By removing moisture upstream of the ozone generator, the SSED stabilizes the ozone generator's rated ozone output. Reducing moisture content in the process gas (air), increases unit performance, and the lifetime of the ozone-generating cell is increased by reducing nitric acid generation. The system includes an SSED upstream from an ozone generator. The SSED has an outer housing divided into two chambers, a cold side and a hot side, by a dividing panel. The SSED has a cold heat sink located in the cold side and a hot heat sink located in the hot side, with a heat exchange unit secured in the dividing panel in contact with both cold and hot heat sinks. Air flow through the hot and cold sides dehumidifies the air in the cold side and is directed to the ozone generator.

An air-purifier system is provided that generates an ionic wind that is comfortable for the persons in a space to obtain a comfortable environment. The air-purifier system includes an air purifier having a first electrode that has first electrode-structures where each has a first conductive area that is substantially shaped as a circular ring between a first hollow and second hollow, a second electrode that has second electrode-structures where each has a third hollow that is larger in diameter than the first hollow and is substantially shaped as a circle between a third hollow and a fourth hollow a holder to fix the electrodes with a gap therebetween, and a third electrode that has third electrode-structures where each extends along the central axis of the first and the second electrode-structure; a sensor that measures environmental data in a space where the air purifier is provided; and a controller that controls the operations of the air purifier based on the environmental data that are measured by the sensor.

An ozonizing device comprises a box-shaped body which encloses therein ventilation device, a discharge ozone generator, an ozone-catalysing UV-C lamp and an additional ozone generator. The box-shaped body comprises a partition wall intended to define two distinct chambers in said box-shaped body: a first chamber in which the ventilation device, the discharge ozone generator and the ozone-catalysing UV-C lamp are housed, and a second chamber in which the further ozone generator is housed which is interfaced with air distribution device associated with a diffuser tube for the diffusion of an ozone-enriched air flow. The ozonizing device further comprises a control unit configured so as to selectively activate, alone or in combination, each of the discharge ozone generator, ozone-catalysing UV-C lamp and the additional ozone generator.

A personal ambient air temperature modification, filtration, and purification system that is configured to be handheld. The personal ambient air temperature modification, filtration, and purification system of the present invention provides a container with air inlets to allow an internal motorized air movement mechanism to pull air through an air channel fluidly coupling to the air inlets, through a filter disposed in the air channel, through thermal diffusion blades, across at least one combination fluid vapor source and thermal energy storage component that purifies the air by vapor capture, into a thermal energy concentrator disposed in the interior volume of the container that modifies air temperature, and through the motorized air movement mechanism, where the air is then delivered into an environment as purified, filtered, temperature modified air.
