The study did not test KN95 masks.
"The disposable masks were KFAD and KF94 models, which were made from thermoplastics polypropylene and polyurethane nylon. These masks have been popularized in South Korea, where the study was conducted, whereas KN95s are more popular in the US."
If, in fact, packaging might make a difference, this study does not specifically address N95 masks.
