The Portuguese textile company Adalberto presented in April a mask with the ability to inactivate microorganisms and, according to it, even the SARS-CoV-2 virus. The MOxATech mask is reusable and can withstand more than 50 washes efficiently, as indicated.
The tests carried out by various microbiological institutes, they assure, guarantee an efficiency of up to 99% reduction of viruses on its surface. In other words, this mask would be useful for inactivating the virus responsible for COVID-19. What is behind this technology?
The “first” commercial mask to eliminate SARS-CoV-2
The MOxAdTech mask, according to Adalberto’s claims, is capable of removing up to 99% of the viral load from your tissues, even after 50 washes. This mask is the result of the joint development of several entities, among which the textile company that markets it, MO Sonae Fashion Retailer, the CITEVE technology center, the University of Minho and the João Lobo Antunes Institute of Molecular Medicine (iMM) .
Xataka contacted IMM from where They confirmed their role as scientific reviewers and virology specialists in the development of masks.. According to the iMM team, led by prestigious virologist Pedro Simas, the mask has passed all viral load reduction tests even after dozens of washes, according to the standards of ISO 18184 of 2019. This is intended to ensure the antiviral capacity in textile parts.
According to the company, the MOxATech mask is registered as a biocidal element on the ECHA 95 list, marketed as an antimicrobial in the European Union. The mask started marketing in April, but it is only so far that the IMM has completed the corresponding tests on its antiviral capacity, its effectiveness was therefore resumed. Currently, it can be purchased in some Portuguese fashion stores and on the Adalberto website for a price of € 10 plus shipping.
An antimicrobial mask to inactivate a virus
The textile technology behind this MOxATech actually takes a while; as explained by Adalberto, the company that created this mask. That consists of several special textile layers, one of which would be water repellent and the other would use, as can be seen from their explanations, a static load of the tissue to induce the bacterial mechanical puncture.
This would give it a great biocidal capacity of microorganisms without contaminating or using other secondary components that could affect health or any other aspect. However, obviously, is this same technology the one behind its antiviral ability? Recall that SARS-CoV-2 is a capsid virus of approximately 100 nanometers.
It is a bit smaller than bacteria and much more physically stable. This poses the question, fully justified, of whether an antibacterial mask can also kill viruses. The details of its mechanism unfortunately seem to lie in trade secrecy, but the evidence approved by the IMM, again according to this entity, confirms the ability of MOxAdTech to inactivate the virus.
The ISO 18184 of 2019 we were talking about aims to ensure quality standards in the corresponding tests, which only certain laboratories are able to determine. Specifically, IMM is one of the few BCL3 (biosafety level 3) in the Iberian Peninsula, and it is a prestigious virological center. The brand warns, however, that This product does not comply with the regulations for surgical masks (Regulation EU / 2017/745), which does not mean that it does not fulfill its capacity to inactivate SARS-CoV-2.
