Wellisair - Advanced hydroxyl radicals technology for disinfection
The OH hydroxyl radical is often called "detergent" of the atmosphere, since it reacts with many pollutants, initiating the process of purifying them. Likewise, it plays an important role in the elimination of greenhouse gases such as carbon dioxide and methane.
The importance of Advanced Oxidation Processes (AOP) is that their application destroys the contaminant and does not concentrate it or transfer it to the environment. In this way, a total or almost total mineralization of organic pollutants is achieved, that is, they have application in the destruction of the vast majority of organic compounds, especially in non-biodegradable compounds such as organochlorines, PCBs, PAHs, etc. It is a clean and safe technology.
Hydroxyl radicals have excellent advantages over the 3 main chemical disinfectants based on chlorine, alkalis and amoni-alcohol-alkali
Wellisair uses a new, innovative and disruptive patented technology that manages to efficiently generate and expand hydroxyl radicals (OH) that, by means of Advanced Oxidation Processes (AOP), eliminate up to 99.9% of pathogenic microorganisms (viruses and bacteria) and, at the same time, reduce volatile organic compounds (VOCs) and PM particles.
Hydroxyl radicals, in addition to being efficient for disinfecting air and surfaces, is a harmless method for humans according to a study published in the scientific journal IJERS “International Journal of Engineering Research and Science”.
Military Defense developed this technology in the 1970s for CBR (Chemical/Biological/ Radiological) warfare. It shows excellent results in the removal of harmful substances such as bacteria, germs and viruses, harmful gases, mold, and respiratory allergens that cause a contaminated environment.
Absence of selectivity of pathogenic microorganisms due to the high oxidation potential of 2.8V (slightly less than fluorine 3.08V).
OH processing time is very short. OH's chemical reaction rate is 107 times greater than other oxidants such as ozone, peroxide or chlorine.
It is a green oxidant, that is, the hydroxyl radicals decompose into water (H2O) and oxygen (O2) without residual oxidants after their biochemical reactions.
The Wellisair’s process of purification and disinfection of air and surfaces through hydroxyl radicals occurs when they come into contact with contaminants, and react as follows:
Products by Wellisair breaks down the membranes of protection from viruses and bacteria (lipid reaction):
Alters the genetic information of viruses and bacteria (lipid peroxidation reaction):
Oxidizes volatile organic components VOCs in heavier products that fall to the ground:
Decomposes particles suspended in the air.
Once the oxidation process has started, the effect called “respiratory explosion” occurs, which consists of a series of cascade reactions that produce more hydroxyl radicals and thus accelerate the process of eliminating viruses and bacteria.
In this way, Wellisair produces a chain effect that efficiently purifies and disinfects the air and surfaces of an area up to 50-60m2.
Wellisair evaporates carefully standardized amounts of a terpene such as d-limonene or hydrogen peroxide (H2O2) from the cartridge, which react with a controlled emission of ozone in low concentrations (<0.02 ppm) generating a constant and harmless production of hydroxyl radicals.
The ozone emission of Wellisair, certified UL in an external laboratory, is below the limit concentration issued by the WHO in the environmental limit values (ELV) of the year 2000 for the general public in exposures up to 8 hours.
Therefore, Wellisair is a safe method, harmless in humans and effective to quickly eliminate pathogenic microorganisms suspended in the air and deposited on surfaces.
