Method: Narrative literature review using articles from the PubMed, Scopus and Web of Science databases, and recommendations from health agencies conducted in April 2020. Results: Protective respiratory devices (particulate respirators) can be reused if it is clean, dry and their layers and shape are intact. To increase the durability of surgical masks, the use of paper towels to absorb moisture is suggested. Cloth masks are recommended, as long as they are washed properly for reuse. Conclusion: Despite the scarce number of studies on the reuse of masks, given the expansion of COVID-19 and the worldwide shortage of this equipment, health professionals and the population must be constantly updated on the recommendations for use of these protective devices.
