Wellisair versus Coronavirus – COVID-19

To understand the effectiveness of Wellisair against the COVID-19 pandemic (initially 2019-nCoV) that emerged in 2019 in Wuhan, one must understand the morphological structure of this type of virus, as well as its classification.

Morphological structure and classification

Coronaviruses are in the Coronavirinae subfamily in the Coronaviridae family, in the order Nidovirales. They are divided into 4 VOC subgenera: Alpha, Beta, Delta and Gamma. COVID-19 belongs to the SARS family, classified as Betacoronavirus of lineage “B”, originating in bats.

Based on the genetic material, these viruses are included in group IV of the Baltimore classification, as the viral particle contains only one strand of positive polarity linear single-stranded RNA.

The diameter of the virus is around 60 to 200nm, they present a nucleocapsid with helical symmetry and a lipid sheath derived from the membrane of the previously infected host cell. From these pods arise the characteristic projections in the form of a solar corona.

Given the short time since the appearance of this strain, direct tests of Wellisair technology against the virus have not been possible.

But it has been possible to test a virus with a morphological structure similar to the coronavirus, such as the Respiratory Syncytial Virus(VRS). RSV is classified within the Pneumovirus, specifically in the Paramyxoviridae family, and although they are not within the same family, this virus shares great similarities with COVID-19, such as the lipid membrane and glycoprotein projections.

The oxidation reactions (lipid oxidation and protein oxidation) that occur in RSV are the same as they should have in COVID-19, so the elimination efficiency should be very similar.

Based on the results obtained with Wellisair in viruses with similar structures (RSV) to Coronavirus COVID-19, we can expect that the effectiveness of our new technology will have an expected average elimination result of 92 to 99% depending on the relative humidity conditions.

Dry 2 hours 92 20191212_4

These conclusions are included in a study carried out by researchers from the Center for Research on Food Safety and Control (CRESCA) of the Polytechnic University of Catalonia (UPC) and the e-SHealth published in the IJORS journal “International Journal of Engineering Research & Science”.

Bibliographic Report University of Barcelona

The microbiology, virology and biotechnology section of the water and food contaminating virus laboratory of the University of Barcelona has produced a bibliographic report on disinfection and the Coronavirus COVID-19.

Coronaviruses that are most similar to SARS-CoV are easily inactivated with commonly used disinfectants, and especially are más susceptibles a aquellos con base alcohólica more susceptible to alcohol-based ones (such as OH hydroxyl radical technology).

The Coronavirus has a morphology very similar to the RSV respiratory syncytial virus tested by the University of Barcelona with a reduction power of 92 to 99% (dry/wet) in 2 hours.

Although ozone is an especially efficient disinfectant for RNA viruses, high concentrations are harmful to living things and therefore not suitable for human-inhabited environments.

On the other hand, with the hydroxyl radicals OH generated by Wellisair, according to the results obtained in our UB laboratory, a similar activation of the Coronavirus is expected without the disadvantages of ozone toxicity.

Wellisair Systems statement in reference to the UB bibliographic report

Wellisair Systems states that the document “Report on stability and disinfection of the new coronavirus 2019-nCoV” from the University of Barcelona is authentic and its content is true.

Faced with the current situation of the Covid-19 pandemic, different distributors, resellers and the media have published erroneous interpretations of this document, even going so far as to say that Wellisair had been validated by the “University of Barcelona” with efficiency against the Coronavirus Covid-19.

Faced with the barrage of inquiries received from the UB to confirm that they had certified Wellisair against the Coronavirus Covid-19, the University of Barcelona has issued a public statement denying these erroneous claims.

Wellisair Systems has not modified or falsified any document or test of any test carried out with our Wellisair equipment in the Laboratory of Food and Water Contaminant Viruses at the University of Barcelona.

We have the original of all the documents of the tests carried out. We enclose the “Report on stability and disinfection of the new coronavirus 2019-nCoV” from the UB, certified in front of a notary in case there is any kind of doubt.

Apart from this bibliographic report, the Laboratory of Water and Food Contaminant Viruses of the University of Barcelona has carried out tests on the efficacy of the Wellisair device (WADU-02 Wellis) for the disinfection of various viruses on surfaces such as Rotavirus, Respiratory Syncytial RSV and Coxsackievirus.

Likewise, we attach the summary tables with the results of the tests carried out by international laboratories and prestigious universities (including the UB) of the main Wellisair applications:
