| T39 |
0-197 |
Sentence |
denotes |
While many recent studies have focused on the penetration of aerosols through various domestic fabrics [19], comparatively fewer studies have looked at outward leakage as opposed to inward leakage. |
| T40 |
198-468 |
Sentence |
denotes |
Better fitting medical or N95 masks have been found to significantly improve the source control of particles from a dummy head [17] and better fits have been achieved with an improved mask design, petroleum jelly [20], adhesive tape or fluffed polypropylene fibers [21]. |
| T41 |
469-656 |
Sentence |
denotes |
For cloth masks, the only study explicitly addressing fit found a large benefit from wearing a nylon stocking worn over the top of a mask [22], although they measured inward leakage only. |
| T42 |
657-880 |
Sentence |
denotes |
Other studies that measured the overall outward mask performance by collecting air around the head did not attempt to separate leakage from fabric penetration as a parameter which contributes to the mask efficiency [23,24]. |
| T43 |
881-994 |
Sentence |
denotes |
The extractive techniques used in many of these studies cannot alone distinguish between leakage and penetration. |
| T44 |
995-1062 |
Sentence |
denotes |
Laser sheets, on the other hand, can visualize the leakage in situ. |
| T45 |
1063-1235 |
Sentence |
denotes |
A flat laser sheet is not optimal for this purpose, for example in the study of Fischer et al. [25], it is not clear whether leakages would be detected in their laser beam. |
