The Armbrust FFR AA-1976 cup-style mask passed our particulate filtration efficiency machine test with a score of 99.69%. A defining characteristic of N95 and N95-style masks is they have either head straps or head ties (no ear loops).
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 212.12.
This mask has no detectable odor. Because Armbrust has applied for (but not yet received) NIOSH certification, the FFR AA-1976 hasn't been officially certified as N95. It will likely not appear for sale until it has been.
This mask's country of origin is the USA. Check out our video review for more details.
