Ozone is a gas naturally present in the stratosphere. It is our natural protection against harmful UV rays. In high concentrations it has a bluish color and a pungent odor. Its concentration in the atmosphere is about 0.04 ppm (parts per million - 1 ppm = 2mg / m3). In nature, ozone can be generated with the strong electric discharge of lightning; it is possible to smell it after a thunderstorm. The electric discharge, acting the oxygen molecule O2, transforms it into a new O3 molecule, namely ozone. Given its high reactivity, ozone tends to dissociate into O2 + O, and it is the latter responsible for the high oxidizing power of ozone. After a certain period of time ozone tends to disappear naturally, reducing itself to oxygen, without leaving any trace. Ozone can also be artificially generated by a process called “Corona effect” starting from the oxygen naturally present in the air and by mean of a machine called “Ozonator”, which produces electrical discharges inside. Its high oxidizing power was discovered by Christian Friedrich Schönbein in 1840. It is so high that it disinfects faster and in lower concentrations than other disinfectants such as chlorine, chlorine dioxide and mono-chloramine. Today, ozone helps us to solve many aspects related to air and water pollution and its use is becoming increasingly widespread, given that its application ranges from the most professisonal environments (hospitals, food industries, communities, gyms , beauty centers, swimming pools ...) to the more household ones, more familiar to us, such as our homes and cars. The use of ozone generates an air oxidation process in the environment in which the treatment is carried out. This process, in a few minutes, attacks and disrupts the cellular components of bacteria, viruses, mold, mites and small weeds, present in the environment. Even at low concentrations, with high humidity, ozone has a high virucidal disinfectant action in the air (ISS COVID Report 19 n. 25/2020). APPLICATIONS Improve air quality in schools, hospitals, offices, homes and businesses. Purifies the water from odors and bacteria. Another useful application is the sterilization of tools, equipment, dishes and work clothes (Certificate of analysis of the University of Udine). POSITIONING The device must be positioned in a place where air can freely circulate around the appliance. Therefore, avoid placing it in niches, close to walls, etc. It is recommended to place it at a height of 1.5m. Select the duration of the treatment following the instructions in the instruction manual. Respect the time period in the instruction manual before staying in the room. In real conditions, the natural decay time required to make the premises accessible is at least 2 hours. If possible, it is preferable to carry out the treatments at night so that when the work resumes, the amount of environmental ozone is within the health safety limits (Rapporto ISS COVID 19 n. 25 /2020). MAINTENANCE Simply clean the product periodically with a damp cloth. Do not use chemicals or detergents on the product. The product does not contain liquids. Note: 1. Use the ozone generator in a clean and dry environment. 2. Do not use when temperatures are very high, above 40 ° C. 3. Do not open the case of the product. 4. Unplug the product if it is not to be used for a long time. 5. Keep the external surfaces of the product clean. Its inactivation action on bacteria, viruses, molds etc ... depends on its concentration in the air and on the exposure time. According to the data provided by the Italian Ministry of Health, the concentrations and timing can be deduced from the following table: Ozone has been recognized by the Italian Ministry of Health (protocol n.24482 of July 31, 1996) natural defense for the sterilization of environments contaminated by bacteria, viruses, spores, etc. and infested with mites, insects etc.
