The Nordiwell mask passed our particulate filtration efficiency machine test with a score of 96.52%. This 3-ply blue surgical mask has 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 59.10.
This mask has a not-unpleasant plastic odor. The construction is phenomenal and the material is super thick without hampering breathability. We do, however, take issue with their ASTM level 3 claim, which they failed to meet (96.52% vs. 98%).We found this mask on Amazon. Its country of origin is China.
