Optical microscopic study of surface morphology and filtering efficiency of face masks |
To measure the effectiveness of cloth masks in filtering aerosol particles and the effect of washing and drying cycles. |
General population |
VI |
Cloth masks are not effective due to low filtering efficiency. And after washing and drying cycles, efficiency deteriorates. |

The effectiveness of respiratory protection worn by communities to protect from volcanic ash inhalation. Part I: Filtration efficiency tests |
To build the first evidence base on the effectiveness of common materials used to protect communities in volcanic crises from ash inhalation. |
General population |
VI |
Standard surgical mask materials can be effective in filtering PM2.5. But other types of masks (single layer not pleated) for use in healthcare environments have performed very poorly against volcanic ash. The fabric materials provided limited filtration. |

Compliance with the use of medical and cloth masks among healthcare workers in Vietnam |
To examine factors associated with using surgical and cloth masks and compliance among health professionals and the relationship of compliance with the results of the infection. |
Health professionals |
II |
Compliance rates for medical and cloth masks decreased when continued use was recommended. Adverse events, such as breathing problems and discomfort, were associated with decreased use of masks, while the perceived risk of acquiring a previous infection increased compliance. |

A cluster randomised trial of cloth Masks compared with medical masks in healthcare workers |
To compare the effectiveness of cloth masks with surgical masks in health professionals. |
Health professionals |
II |
Infection rates were higher for cloth masks compared to surgical masks. Particle penetration in cloth masks was almost 97% and in surgical masks, 44%. Moisture retention, reuse of cloth masks and insufficient filtration can result in an increased risk of infection. |

Testing the efficacy of homemade masks: would they protect in an influenza pandemic? |
To examine homemade masks as an alternative to commercial masks. |
General population |
