Wu additionally famous the potential of enhancing fit by using a rubber overlay, which has additionally been rediscovered recently . However, there are not any modern studies of the efficacy of a full range of masks designs and materials combinations, using probably the most relevant circulate charges (at relaxation or low exertion rate of 15 L/min), and contexts .

Studies suggest that vibration of the vocal folds contributes extra to particle atomization and the production of particles that carry microorganisms .
