The OSR-M1 has been independently tested at three different labs for filter efficiency, breathability, and fluid splash, however it is not yet certified. We have high confidence in the performance of the mask, and intend to apply for certification once we complete building an ISO compliant quality management system. The test results can be found further down the page.
Test results: OSR-M1
Filter Efficiency (instantaneous) ≥99%
Tested to filter more than 95% of airborne particles greater than 0.075µm particles.
Testing Procedure: TEB-APR-STP-0059.
Exhalation Resistance = 13.0 mmH20
Minimizes resistance on exhalation.
Testing Procedure: TEB-APR-STP-0003
Inhalation Resistance = 17.1 mmH20
Minimizes resistance on inhalation.
Testing Procedure: TEB-APR-STP-0007
Residual CO2 (10 min avg.) = 1.778%
Tested to maintain less than 2% of CO2 on average in mask.
Testing Procedure: RCT-APR-0064-508
Blood Splash: pass at 635cm/s
No synthetic blood penetration at 635 cm/s.
Testing Procedure: ASTM F1862
Face Fit: Pass Breathability Tests
Must have face-fit to pass Inhale/Exhale Resistance tests (above).
