Wellisair: Hydroxyl Radicals Technology

WellIsair - Advanced Hydroxyl Radicals Technology For Disinfection

Wellissair uses a new, innovative, and disruptive patented technology that efficiently generates and expands Hydroxyl Radicals (OH·) in order to trigger Advanced Oxidation Processes (AOP) for the elimination of up to 99.9% of pathogenic microorganisms (viruses and bacteria), at the same time as reducing Volatile Organic Compounds (VOCs) and PM particles.

Hydroxyl Radicals are not only highly efficient when it comes to disinfecting both the air and surfaces, but they are also a method which is completely harmless to humans, according to a study published in the scientific journal IJOER “International Journal of Engineering Research and Science”.

In the 1970s, Military Defence used OH· in the atmosphere to develop this technology for CBR (Chemical/Biological/Radiological) warfare. It was first commercialized in the 1990s for use in European hospitals and has proved to be very effective at removing harmful substances such as bacteria, germs and viruses, harmful gases, mould, and respiratory allergens, which can all lead to a contaminated and harmful environment to humans.

Within the Reactive Oxygen Species (ROS), Hydroxyl Radicals (OH·), when used in small concentrations, can be employed to carry out biocidal functions on viruses, bacteria, allergens and mould, in order to erode any organic compounds found in the air and turn them into minerals or harmless water-soluble organic compounds.

The OH· Hydroxyl Radical is the most important natural oxidant in tropospheric chemistry. This molecule is often referred to as the atmosphere's "detergent", as it reacts with a large number of pollutants to kick-start the purification process. It also plays an important role in eliminating Greenhouse Gases, such as Carbon Dioxide and Methane.

Advanced Oxidation Processes (AOP) are particularly powerful as they are able to destroy pollutants without concentrating or transferring harmful substances into the surrounding environment. This allows for a total or almost total mineralisation of all organic pollutants, meaning that the vast majority of organic compounds are destroyed, especially when dealing with non-biodegradable compounds such as Organochlorines, PCBs, PAHs, etc. It's also a very clean and safe technology.

Hydroxyl radicals have excellent advantages over the 3 main chemical disinfectants which are made using chlorine, alkalis and amoni-alcohol-alkali:

• Absence of selectivity when it comes to pathogenic microorganisms, due to the high oxidation potential of 2.8V (slightly less than fluorine 3.08V).
  
  
• OH processing time is very short. The OH· chemical reaction rate is 107 times greater than other oxidants, such as ozone, peroxide, or chlorine.
  
  
• They are considered to be an "eco oxidant", as Hydroxyl Radicals naturally decompose into water (H₂O) and oxygen (O₂), without leaving behind any residual oxidants once their biochemical reactions have finished.
  
  

Wellisair works by purifying and disinfecting air and surfaces by means of Hydroxyl Radicals, which react in the following way when they come into contact with pollutants:

• Breaks down the protective cell-membranes of viruses and bacteria (lipid reaction).
  
  
• Alters the genetic information in viruses and bacteria (lipid peroxidation reaction).
  
  
• Oxidizes Volatile Organic Compounds VOCs, converting them into heavier particles that automatically fall to the ground.
  
  
• Decomposes particles suspended in the air.

Once the oxidation process has begun, a “respiratory explosion” effect occurs, which consists of a series of cascade reactions that produce more Hydroxyl Radicals and thus accelerates the elimination process of any viruses and bacteria.

In this way, Wellisair produces a chain effect to effectively purify and disinfect the air and any surfaces of up to 50-60m².

Wellisair works by carefully dissipating standardised amounts of Terpene, such as D-Limonene or Hydrogen Peroxide (H₂O₂) from the interior cartridge, which reacts with a controlled emission of ozone in low concentrations (<0.02 ppm) to generate a constant and harmless production of Hydroxyl Radicals.

The ozone emissions emitted by Wellisair, which is UL certified by an external laboratory, is below the concentration limit established by the WHO in their 2020 Emission Limit Values (ELV) for the general public for exposures of up to 8 hours.

Therefore, it is a safe,effective and harmless method for quickly eliminating pathogenic microorganisms suspended in the air or deposited on any surfaces.
