Coronavirus
Disinfection by the SARS-CoV-2 COVID-19 coronavirus
For the effectiveness of Wellisair against the coronavirus pandemic COVID-19 (initially 2019-nCoV) appeared in Wuhan in 2019, it is necessary to understand the morphological structure of this type of virus, as well as its classification:
Coronaviruses belong to the Coronavirinae subfamily of the Coronaviridae family, in the order of Nidovirales. There is no subdivision into 4 different types of VOCs: Alpha, Beta, Delta in Gamma. COVID-19 matches the SARS family, classified as Betacoronavirus of the “B” line, derived from bats.


Based on genetic material, these viruses are included in Group IV of the Baltimore Classification because the viral particle contains only a single, single-chain, linear positive polarity RNA chain.
The diameter of the virus is about 60-200 nm, they have a helically symmetrical nucleocapsid and a lipid sheath derived from the membrane of the previously infected host cell. From these pods emerge characteristic projections in the form of a solar corona.
Due to the short onset time of this strain, direct testing of Wellisair technology against the virus has not been possible.
It was possible to test a virus with a morphological structure similar to the coronavirus, such as respiratory syncytial virus (RSV).RSV is classified among the pneumoviruses, more precisely in the Paramyxoviridae family, and although it is not part of the same family, this virusshares great similarities with COVID-19 as lipid membrane and glycoprotein projections.
The oxidation reactions (oxidation of lipids and oxidation of proteins) that occur in RSV are the samethat they should have in COVID-19, so
the removal efficiency should be very similar.
Based onresults obtained with Wellisair in structurally similar viruses (RSV) to the COVID-19 coronavirus, we can expect that the efficiencyof our new technology will have an expected elimination result of 92-99% on average based on relative humidity conditions.
Bibliographic report University of Barcelona
The microbiology, virology and biotechnology section of the laboratory for contamination of viruses in water and food at the University of Barcelona has produced a bibliographic report on disinfection and the COVID-19 coronavirus.
Plus coronaviruses like SARS-CoV are easily inactivated with commonly used disinfectants and are particularly more sensitive to alcohol-based disinfectants (such as hydroxyl OH 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 a particularly effective disinfectant for RNA viruses, high concentrations are harmful to living things and therefore not suitable for human-inhabited environments.
In contrast, with the OH hydroxyl radicals generated by Wellisair, according to the results obtained in our laboratory, we would expect a similar inactivation of the Coronavirus without the drawbacks of ozone toxicity.
Bibliographic report University of Barcelona
Airtècnics declares that the document "Report on the stability and disinfection of the novel 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, various distributors, resellers and 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 effectiveness against the Coronavirus (COVID-19.
Faced with the barrage of inquiries received from UB to confirm that they had certified Wellisair against the Covid-19 coronavirus, the University of Barcelona issued a public statement denying the false allegations.
Airtècnics has not modified or falsified any document or test of any test carried out with our Wellisair team in the Laboratory of Food and Water Contaminants at the University of Barcelona.
We have the original of all test documents. We are enclosing the UB's “Stability and Disinfection Report for Novel Coronavirus-nCoV 2019”, notarized in case of doubt.
Apart from this bibliographic report, the Laboratory of viruses contaminating water and food at the University of Barcelona has carried out tests on the effectiveness of the Wellisair device (WADU-02 Wellis) to disinfect various viruses. on surfaces such as Rotavirus, Respiratory Syncytial RSV and Coxsackievirus.
We take this opportunity to attach the summary tables with the results of tests carried out by international laboratories and prestigious universities (including UB) of the main applications of Wellisair:
- Virus removal
- Elimination of bacteria
- Air quality
- Odor elimination
- Real success stories
