Multi-layer protection provides full coverage with an electrostatic filter. The ‘charged’ meltblown layer provides at least 99% filtration efficiency of 0.1-micron aerosolized saline particles.
Designed with double head straps and a flexible nosepiece for optimal seal and all-day comfort. Our leading consumer-grade straps provide 0.8 to 1.25lbs of force to maintain an adequate seal.

Particulate Filtration Efficiency
blox Average Lot Filtration Efficiency
The NIOSH N95 filter efficiency as stated in 42 CFR Part 84.181 is a minimum efficiency for each filter of ≥95% (≤5% penetration). The test articles submitted conform to the NIOSH N95 criteria for filter efficiency.

Inhalation and Exhalation Resistance
The inhalation resistance criteria is an initial inhalation not exceeding 35 (mm H20) water column height pressure.
The exhalation resistance criteria is an initial exhalation not exceeding 25 (mm H20) water column height pressure.
blox respirators have an average of 7.3 (mm H20) resistance on inhalation and 9.4 (mm H20) on exhalation.The full Nelson Lab Inhalation and Exhalation Testing Results (PDF) Download
