NEN-EN 149 Respiratory protective devices – Filtering half masks to protect against particles – equirements, testing, marking. From a morphological point of view, our results show that using a disposable face mask for several hours, without proper disposal or cleansing, may lead to collecting, growing, and cumulating inorganic as well as organic matter. This observation adds another noteworthy factor to the increasing discomfort and the significant drop in filtering performance. Moreover, our pictures confirm the assertions of previously published papers regarding bacterial formations39, providing new meaningful elements on this subject. The combined elements of high RH and relatively high temperature inside the mask, could create a microclimate within the face mask, including the growth of fungal and bacterial colonies.

Evidence from randomized controlled trials that surgical masks reduce infection from diseases such as influenza is weak. Although a recent very large study found some evidence that they reduced transmission in the community, surgical Disposable masks masks can vary greatly in quality which may make these studies less useful. The effect of surgical masks is partially attributed to filtering out some of aerosol particles that are how airborne diseases are transmitted.
As noted above, masks with only one layer of fabric don’t offer nearly as much protection as masks made from two or more layers. For this reason, we also don’t think single-layer masks or most gaiters are the best choice . We also don’t recommend any masks for kids with filter pockets, which allow you to add and remove a disposable filter. In most of these masks, the filters are smaller than the mask, allowing airborne face mask particles to pass around the filter. Because breathability is important both for comfort and protection, more layers is not necessarily better, said Taher Saif, PhD, a mechanical engineering professor at the University of Illinois at Urbana-Champaign. Adding too many layers of fabric or a filter can force air in and out around the mask , instead of through it; this could make the mask less effective overall.
