The SEJIN-AIRSOOM mask passed our particulate filtration efficiency machine test with a score of 98.98%. KF94 masks are boat-style and made in Korea, which has very strict production guidelines. All KF94 masks have ear loops instead of head straps or head ties.
Mask breathability is determined by airflow resistance, which we measure in pascals. The target for adults should be around 150, and the target for children should be close to 100. The airflow resistance of this mask is 168.
This mask is one of the best-smelling KF94s we've tested. The breathability isn't ideal for multiple hours of wearing, but the lack of odor is a plus if you insist upon a KF94.
