The COVID-19 pandemic is posing a huge global health threat. To deal with this
problem, in addition to research and work in the medical field, the main health
measures being taken in the workplace and at home involve the establishment of
safety protocols, which include distance measures, hygiene and the use of
personal protective equipment, such as masks, etc. The WHO still does not
recommend the use of masks for the general population. However, their successful
use in China, South Korea and the Czech Republic has encouraged their widespread
use, and the shortage that already existed. This has caused that companies and
individuals are looking at the best way to reuse them, and to manufacture,
homemade or not, of non-certified masks. This paper is based on two objectives:
to consult the scientific literature to identify the main strategies for
disinfecting them, and to determine the effectiveness of non-certified disposable
masks. A rapid review has been conducted in which the main publications and other
information available online have been analyzed. Results showed that the most
promising methods are those that use hydrogen peroxide vapor, ultraviolet
radiation, moist heat, dry heat and ozone gas. Soapy water, alcohol, bleach
immersion, ethylene oxide, ionizing radiation, microwave, high temperature,
autoclave or steam are not fully recommended. Regarding the effectiveness of
surgical masks compared to PPE, the former have been seen to be slightly less
effective than PPE. As for other types of masks the effectiveness of homemade or
non-certified masks is very low.
