The Gerson 3230+ passed our particulate filtration efficiency machine test with a score of 96.89%. A defining characteristic of N95 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 55.60.
This mask has a slight rubbery odor, but it's great mask otherwise. It gets a hearty recommendation from us.
We found this mask on Amazon. Its country of origin is the USA. Check out our video review for more details.
