In order to obtain certification as an N95, a respirator must pass NIOSH’s test requirements, which include Exhalation Resistance, Inhalation Resistance and Sodium Chloride (NaCl) N95 Filtration. As the charts below indicate, the B100 easily passed the NIOSH, N95 respirator performance criteria Results presented in tables below are as obtained from testing performed by NIOSH to obtain approvals for the B130/B150 as N95 respirators.
