Tinta unita o fantasia, bianche o colorate: di mascherine di stoffa ce n’è per tutti i gusti. Ma sono davvero sicure? Un test mette sotto la lente otto mascherine - con e senza certificato di laboratorio a prova di Task Force Covid - per valutare l’efficacia di filtrazione e la resistenza respiratoria. Sono state tutte acquistate in negozi e supermercati svizzeri. Il risultato? …da togliere il fiato.
