Test reports for Wellisair device WADU-02

One of the great applications of Wellisair technology is virus removal. These can be divided into two large families: enveloped viruses and viruses without envelope. The main difference between them is that the enveloped viruses have a protein matrix that surrounds the nucleic acid (virus genetic information, RNA). Despite what might be expected, that matrix is sensitive to external agents such as oxidation.

The Advanced Oxidation Process (POA) of Wellisair India based on hydroxyl radicals, allows attacking the two types of viruses, but in a different way:

  • Enveloped virus: the hydroxyl radicalsreleased by Wellisair products react with the fatty acid chains in the envelope (lipid reaction). This reaction breaks the membrane, a fact that produces an antioxidant reaction in the virus that accelerates its destruction (indirect protein oxidation reaction produced by lipid peroxidation) by altering its genetic information.

Alters the genetic information of viruses and bacteria (lipid peroxidation reaction):

  • us without envelope: the oxidation directly attacks the genetic information of the virus (direct protein oxidation produced by ROS), making it useless and touched by death.

In order to determine the effectiveness of the Wellisair technology, different tests on various viruses and with different humidity conditions were carried out at the Laboratory of virus contaminating water and food at the University of Barcelona:

  • Syncytial RSV

  • Graph 1. Decrease in the concentration of RSV Syncytial plaque forming units per millilitre (PFU / ml) in dry medium

  • Graph 2. Percentage reduction in the concentration of Syncytial VRS plaque forming units in dry medium.

  • Rotavirus:

  • Graph 3. Decrease in the concentration of Rotavirus plaque forming units per millilitre (PFU / ml) in dry medium

  • Graph 4. Percentage of reduction of the concentration of plaque forming units of Rotavirus in dry medium.

  • Coxsackievirus:

  • Graph 5. Decrease in the concentration of Coxsackievirus plaque forming units per millilitre (PFU / ml) in dry medium.

 Graph 6. Percentage reduction in the concentration of Coxsackievirus plaque forming units in dry medium.

The results of these tests ensure Wellisair works well against virus elimination, since the oxidation process will behave similarly in viruses with a similar morphological structure.
