A collaboration between several Portuguese companies and scientific and academic centers has allowed the development of a mask that inactivates the virus that causes Covid-19 , endorsed by the João Lobo Antunes Molecular Medicine Institute in Lisbon (iMM).

The mask, called MOxATech , has been on sale since April, but its ability to inactivate the virus has only now been confirmed by a series of tests carried out by the iMM, the entities that make up the project have reported in a statement.

This protective equipment, which has a coating that neutralizes the virus when it comes into contact with it, has been developed thanks to the collaboration between the textile manufacturer Adalberto, the retail company MO, Sonae Fashion , the CITEVE technology center, iMM and the Universidade do Minho.

The virologist of the iMM Pedro Simas , who coordinated the tests, assured that the tests carried out "have shown an effective inactivation of SARS-CoV-2 even after 50 washes, observing a 99% viral reduction after one hour of contact with the tissue "

To test its efficacy, the tissue was analyzed after being in contact with a solution containing a certain amount of virus, to measure its viability over time.

Before the iMM confirmed its efficacy in inactivating the Covid-19 virus , the Institut Pasteur de Lille in France had already successfully tested its antimicrobial properties against the H1N1 virus, Corona-type and rotavirus.

The mask, developed with a technical fabric that integrates several different layers, waterproof and reusable, also has a certification from the French Direction Générale des Entreprises that accredits a particle retention of 96%, even after 50 washes .

Although they are now for sale only in the stores of the Portuguese brand MO, available throughout the European Union, the project was opened to the community so that other brands in Portugal and abroad can distribute them.
