Previous studies have shown that the concentration of VOCs inside confined environments is, in some cases, 5 times higher than the concentration of Indoor Pollution and Photocatalysis 7 of the external environment (AP Jones, 1999). The health effects of exposure to volatile organic compounds depend on the duration of exposure, the frequency of exposure, the type and concentration of the pollutant. Frequent and prolonged exposures to volatile organic compounds such as benzene, p-dichlorobenzene, chloroform, methylene chloride etc. they can lead to the development of tumors. Given the previous considerations, the study of the abatement of these compounds in confined environments with innovative techniques is of considerable importance. The secret lies in the oxidative process of photocatalysis of which Titanium dioxide (TiO2) is responsible, which, in the presence of light (ultraviolet rays), attracts and retains the H2O molecules (humidity) naturally present in the air, capturing the dust thin and with them nitric oxide. An oxidation process that already occurs naturally but that the photocatalysis accelerates, favoring a more rapid decomposition and avoiding the accumulation of harmful substances.



- Negative ions 100 million sq cm


As early as 1930, Dessauer discovered that IANs positively affect our health. In 1940 Tchijevski, a Russian researcher, proved that fully deionized air quickly leads to death. Since then, thousands of studies have been published by universities and medical research centers around the world on the benefits of air ionization on human health. Everyone came to the conclusion that air ions are essential to "clean the air" and to "improve our health". The air ions can even electrically charge the AIR CONTAMINANTS which consequently aggregate and settle on ground surfaces. They can also oxidize volatile molecules, deodorizing the atmosphere. IANs have been shown to help our body rebalance, activate and strengthen certain essential functions, such as oxygenation of the body and the immune system, to regulate some essential mechanisms, such as the production of neurooronomi and blood circulation, and to improve our psychological health. IANs are therefore as important as vitamins and trace elements, even at low concentrations, and are therefore considered to be “the vitamins of the air”! The higher their concentration in the air, the cleaner the air and the higher the oxygen concentration in our body. In the vicinity of the “Iguaçú” waterfalls in Argentina, the highest concentration of air ions in the world has been found, about 8 million IAN / cm 3. Studies have shown that the people living in this area hardly ever get sick. On the other hand, people living in polluted areas, devoid of IAN, are more exposed to physical and mental illnesses.

- Ozone


Ozone can be used as a safe and effective agent to improve air quality, an essential condition for sanitizing environments. The use of ozone guarantees the control, if not the complete abatement, of the majority of pollutants present in the air (dust, gas, viruses, bacteria, molds, spores) which very frequently develop in air conditioning systems and in ducts ventilation, from which they are conveyed to the surrounding environments. Ozone has a high oxidizing power, which allows it to quickly neutralize the most resistant pathogens, while its peculiarity of converting itself back into oxygen in a short time without leaving residues, makes ozone the ideal disinfectant agent for the most recent needs in sanitation area. - UV-C Typically, germicidal lamps used in sterilization systems have a dominant emission around the wavelength of 253 nm (nanometers). Components with a wavelength less than 250 nm are generally filtered to prevent the risk of ozone production. In these cases the lamp is defined as “ozone free”. If the UV components with a wavelength lower than 250 nm are not shielded, the safety procedures to prevent exposure to ozone must also be implemented, as indicated in the paragraph “Treatment with Ozone”. UV-C radiation has the ability to modify the DNA or RNA of microorganisms, preventing them from reproducing and therefore being harmful. For this reason it is used in various applications, such as the disinfection of food, water and air. In vitro studies have clearly shown that UV-C light is capable of inactivating 99.99% of the influenza virus in aerosol (44,45). The virucidal and bactericidal action of UV-C rays has been demonstrated in studies on the MHV-A59 virus, a mouse analogue of MERS-CoV and SARS-CoV-1. Application to droplets containing MERS-CoV resulted in undetectable levels of the MERS-CoV virus after only 5 minutes of exposure to the UV-C emitter (a percentage reduction greater than 99.99%) (46) and resulted in also effective in the sterilization of blood samples. (47) In particular, the inactivation of over 95% of the H1N1 influenza virus aerosolized by a nebulizer capable of producing aerosol droplets similar in size to those generated by cough has been demonstrated and human respiration. The study by Bedell et al. (46) describes the experiments concerning the efficacy studies of a rapid, efficient and automated method of disinfection of surfaces based on UV-C radiation, potentially able to prevent the spread of viruses in healthcare facilities. The limit values set by current legislation in relation to the use of germicidal lamps with UV-C 180-250 nm emission have recently been confirmed by the SCHEER (Scientific Committee for Consumer Safety) in relation to the evidence that accidental exposure to UV-C generated by germicidal lamps in this wavelength range is capable of causing severe erythemal damage, burns and severe forms of photokeratitis and photoconjunctivitis subjects unknowingly exposed even for short periods (SCHEER -Health effects of UVC lamps 2017) (51)
