One of them is the one that involves the use of ozone as a disinfectant method. These are household appliances that are programmed to expel ozone into the air every certain time and thus eliminate any organism or bacteria harmful to health.
Ozone is a gas that we find in nature, very useful for its exceptional properties to achieve deep hygiene. Not in vain, ozone is the most powerful natural disinfectant that exists, surpassing by several thousand times the results of bleach or other chlorinated products traditionally used for this purpose.
With the advantage that it does so without posing a danger to health, as long as proper use of the ozonizing equipment is made. In this sense, its level of safety depends above all on the devices guaranteeing non-toxic ozone levels.
Regardless of the differences that may exist between regulations, ensuring safe ozone levels is a constant in the different legislations. On the other hand, meeting these safe levels is one of the main keys to its great usefulness and versatility in the different areas in which ozone has been used for decades with great success.
Ozone is used in very diverse fields that include industrial, professional and also domestic uses, and in each of them we find devices designed to satisfy the different needs that may arise.
One of the characteristics of domestic equipment is precisely its adaptation to a type of non-specialized user, while at the same time offering features tailored to the demands of a home and, in short, of a family.
Needs that range from obtaining quality air, free of organic and inorganic contamination, as well as bad odors, to the purification of potable water for drinking or for personal hygiene, in addition to being very practical for cleaning the home.
Regarding the degree of microbiological contamination, taking into account that the World Health Organization (WHO) advises that microorganisms in indoor environments do not exceed 500 colony-forming units (cfu), we have ozone technology to help reduce those levels. A healthy environment, therefore, must have lower levels, and achieving it in homes will be much easier than in critical public places, where these values can easily skyrocket.
Therefore, the work carried out by domestic ozonators will be effective enough to achieve ideal disinfection without posing a health risk thanks to ozonation that we can carry out without problems in the presence of people.
Even so, if we want to maximize safety conditions, it will be enough to leave the room for a few minutes and let the device perform the treatment, as this will be a sufficient period of time to achieve optimal results.
Why is it safe to use?
In short, the concentrations allowed by regulatory standards for domestic ozonators are safe, so the use of such devices cannot endanger health.
Domestic ozonators are designed for the treatment of atmospheres, surfaces, food and water by injecting this gas in minimal quantities into the air or water. As we have pointed out, after its action, which lasts just a few minutes, the ozone is converted into oxygen, considered harmless for people and the environment.
In its toxicological file, ozone is not considered carcinogenic, but rather an irritating agent in the air for a certain exposure time and at certain concentration levels, which domestic ozonation devices do not reach.
At the international level, the WHO recommendations are a reference, which stipulates a maximum concentration of ozone in the air for the general public of 0.05 ppm (0.1 mg/m3), for daily exposures of eight hours, as well as than the safety recommendation of Spanish legislation of <100 µg/m3 (UNE 400-201-94), which is based on WHO recommendations.
Regarding its dissolution in water, its rapid decomposition and other factors associated with domestic ozonators, such as its low concentration, allow safe use for the disinfection of drinking water. Its use, respecting the safety recommendations of the regulations, does not represent any problem.
Specifically, ozone is authorized as an adjuvant in the treatment of drinking water while it is recognized as a disinfectant in the purification of water (UNE-EN 1278:1999), in addition to its use being authorized in the presence of people and food, according to the Royal Decree 140/2003, of February 7.
On the other hand, community regulations include ozone in the list of marketable biocides in Directive 98/8/EC of the European Parliament and of the Council of February 16, 1998, a regulatory framework in which the use of ozonators was framed. domestic.
