  • the device is designed in such a way that it also allows the elimination of excess ozone that may be in the air.
  • Air filters are known in the state of the art, technologies such as ultraviolet radiation tubes are also known, and also ozone generators as well as photocatalysis means. In some cases, combined means are used but no device is known that offers the possibility of being able to combine all the previous means in a single device. The combination of all the media and technologies is not the result of a simple combination but has required the study and design of a device in which the different technologies are properly combined to achieve their most convenient operation.
  • the object of the present invention is an air purifying device that combines different technologies with a particular design that allows the admission and diffusion of air with maximum effectiveness and treatment, in addition to being able to select the different technologies.
  • the air purification device comprises
  • a particle filter that is fixed on the support base, which in a possible embodiment has a level up to U15 through a HEPA filter, and which can also include pre-filters or intermediate filter elements.
  • this filter can be replaced by a simple labyrinth of perforated sheets for cases where particle filtration is not necessary, either due to the characteristics of the room or to avoid the necessary maintenance.
  • an active photocatalysis applicator surface indirectly attached to the support base where the active surface presents a high flow honeycomb format, capable of inactivating really harmful substances such as formaldehydes and VOCs (carcinogenic elements) that are found in many plastics and construction elements.
  • the active surface is coated with T ⁇ 0 2 nanoparticles, which react to UV light inside the device, emitting hydroxyl radicals that react with organic substances to decompose them into non-toxic, as well as microorganisms.
  • the photocatalysis unit contributes these radicals to the air flow that circulates through the treatment equipment to reach the entire volume of the room.
  • a means of ultraviolet radiation in the preferential range of 254nm wavelength which comprises an ultraviolet radiation chamber and tubes for the emission of said radiation housed inside the chamber, these ultraviolet radiation means being placed above the photocatalysis applicator active surface.
  • Said chamber can be built internally with radiation reflective elements, to improve performance.
  • UVC radiation is properly controlled within the equipment, since it can damage the retina and produce alterations in the skin if it is exposed directly, at any intensity or power. Due to the construction of the device, this radiation to the outside is canceled in the presence of people.
  • Low pressure lamps are preferably used, given their characteristics, and with a filter to avoid the generation of ozone in the presence of people. These lamps are relatively powerful since UVC radiation requires a high dosage. to be really effective. Unlike other household equipment, the device has more than 35mJ / cm2, above the resistance of most harmful organisms.
  • Part of the radiation used in the UVC radiation chamber is used to sensitize the photocatalysis stage, reducing costs and making the equipment more compact and easy to maintain.
  • the location of the radiation chamber is important, since the particles and organisms that escape the HEPA filtering (0.005%) are the ideal size to be inactivated by UVC radiation, so it behaves more efficiently with small sizes while HEPA takes care of the larger ones.
  • UVC radiation also constantly affects the organisms trapped in the HEPA filter, so they end up being inactivated within the filter itself, not being a simple brake and collector of them. This further increases the efficiency of the HEPA filtration stage.
  • This topology is unique and very efficient when the filter is reaching a saturation level, which could even be detrimental when storing unwanted organisms during the lifetime

  • the ozone generation system also has a sensor for measuring the concentration of this gas in the air, which is continuously compared with the programmed target to modulate the operation. This sensor is also used in a complementary way to activate an optical-acoustic signal of non-permanence in case of being above the safety threshold for people.
  • this ozone sensor in case of detecting a high concentration of ozone in the air is put into operation to make the air pass through activated carbon filters and reduce the concentration of ozone in the air, thus avoiding the use of secondary equipment for the active elimination of ozone.
  • the air purifying device can have a second motor placed in one of the slots, forcing the air to circulate through the slots and through the activated carbon filters, not making it necessary to drive the internal motor associated with the ozone generator.
  • the air purifying device can function as direct UVC radiation equipment on surfaces:
  • the UVC radiation source can have motorized gates that can be opened towards the room, directing the radiation directly on the surfaces of the room. In this way, an additional technique is applied to the previous ones when the device is programmed to activate in hours of non-human activity, and under the supervision of the presence sensors as a security measure.
  • This radiation reaches surfaces of objects in the room, inactivating harmful organisms in situ during the night hours, for example.
  • - means of sensorization and control among which one or combinations of the following may be available: o Wireless communication via Wi-Fi or similar with an integrated management system.
