Resumo: Objective: To describe the recommendations, physical characteristics, methods of disinfection and the effectiveness of using homemade masks in reducing the transmission of COVID-19. Methods: Search was performed in the MEDLINE, SciELO and Google Scholar databases, in addition to the official recommendations for use. Results: 31 references were included. The filtration capacity of tissues varied between 5 and 98%. 100% cotton fabrics in two or three layers showed filtration efficiency between 70 and 99%, in vitro. Homemade masks, surgical and respirators showed breathability between 2.2 to 3.0 Pascal. The ability to reduce the spread of microorganisms by people wearing home masks was three times less than when using surgical masks, but it was superior to not wearing masks. Conclusion: The breathability of homemade masks may be adequate, while the filtration efficiency seems to be inferior to surgical masks, but superior to no mask use. There is no evidence to support the efficacy and effectiveness of homemade masks.

Métodos: Realizou-se busca nas bases de dados MEDLINE, SciELO e Google Scholar, além das recomendações oficiais de uso. Resultados: Foram incluídas 31 referências. A capacidade de filtração de tecidos variou entre 5 e 98%. Tecidos 100% algodão em duas ou três camadas apresentaram eficácia de filtração entre 70 e 99% em estudos in vitro. Máscaras caseiras, cirúrgicas e respiradores apresentaram respirabilidade entre 2,2 e 3,0 Pascal. A capacidade de redução da propagação de microrganismos por pessoas usando máscaras caseiras foi três vezes menor do que ao usar máscaras cirúrgicas, embora tenha sido superior ao não uso de máscaras. Conclusão: A respirabilidade de máscaras caseiras mostrou-se adequada, enquanto a eficácia de filtração parece ser inferior à das máscaras cirúrgicas, mas superior a não usar máscara. Não há evidências que respaldem a eficácia e efetividade das máscaras caseiras. SciELO PreprintsSciELO PreprintsSciELO Preprints2021-06-22info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/249610.1590/s1679-49742021000400003porhttps://preprints.scielo.org/index.php/scielo/article/view/2496/4281Copyright (c) 2021 Iago Torres Cortês de Sousa, Aylla Mesquita Pestana, Larissa Pavanello, Michelle Franz-Montan, Karina Cogo-Müllerhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSousa, Iago Torres Cortês de Pestana, Aylla Mesquita Pavanello, Larissa Franz-Montan, Michelle Cogo-Müller, Karina reponame:SciELO Preprintsinstname:SciELOinstacron:SCI2021-06-22T17:42:16Zoai:ops.preprints.scielo.org:preprint/2496Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2021-06-22T17:42:16SciELO Preprints - SciELOfalse
