The Caleegi disposable mask passed our particulate filtration efficiency machine test with a score of 97.12%. This 4-ply black 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 88.
This mask has a musty odor. We were, however, impressed by the ear loops and the double nose wire. The breathability could be better for this kind of mask, but that's due to the thickness of the material.We found this mask on Amazon. Its country of origin is China.
