SUMMARY:
The engagement against COVID-19 is the focus of efforts worldwide. The use of masks is recommended by the World Health Organization, as a means to stop the spread of the virus, and there is a huge amount of these discarded in the environment. Thus, the challenge was to patent a low-cost equipment that would allow the reuse of masks safely, performing the disinfection and sterilization process using a chemical and two physical agents. The equipment is based on the use of Polyhexamethylene Biguanide Hydrochloride, Ultraviolet Radiation and Dry Heat. All processes are automated and controlled by a timer relay in 3 cycles, and consists of a thermo-resistant plastic box, and other items use low financial resources, with easily acquired materials, such as hair dryers, cars' wiper nozzles and ultraviolet lamps. The masks underwent microbiological tests on fungi, bacteria and viruses, as well as filtering efficiency. The microbiological tests were carried out with Candida albicans, Staphylococcus aureus, Escherichia coli, and avian coronavirus ACoV, which after being subjected to the disinfection process in the prototype and evaluated for the growth of microorganisms in the specific environment. No growth of the pathogens was observed in these, which demonstrated the effectiveness of the prototype. The equipment is budgeted at approximately US$ 214.00. The prototype patent was filed under number BR 1020210166320.
