The COVAFLU KN95 mask passed our particulate filtration efficiency machine test with a score of 99.15%. All KN95 masks are flat fold and have ear loops instead of head straps or 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 169.
This mask has an odor that smells like a laundry room. The ear loops are comfortable, but flimsy. The seal is good, but the ear loops snapped during testing.
