Surgical Mask Lab Test Results
To ensure our products exceed the highest possible safety and quality standards, Response Medical independently verifies that their Type 1 and Type 2 surgical masks meet and exceed ASTM Level 1 and Level 2 requirements.
ASTM International sets the preferred international standard for best practices in testing and material performance requirements. The FDA, who oversees the sale and marketing of all surgical masks, recommends that manufacturers demonstrate mask performance in these areas:
- Filtration Efficiency
- Differential Pressure
A leading provider of independent microbiological and analytical lab testing, Nelson Labs, has certified that Response Medical Surgical Masks meet and exceed the metrics for an ASTM Level 2 rating.
Bacterial Filtration Efficiency (BFE)
Bacterial Filtration Efficiency or BFE is a measurement of our surgical mask's resistance to the penetration of bacteria. Results are reported as percent efficiency and correlate with the ability of our masks to resist bacterial penetration. Higher numbers in this test indicate better barrier efficiency. Response Medical Surgical Masks earned filtration efficiency ratings well over the 98% required for ASTM Level 2.

Particle Filtration Efficiency (PFE)
Particle filtration efficiency or PFE is a measurement of our surgical mask's ability to filter particles of different sizes. The particle size tested can range between 0.1 to 5.0 µm in size. Higher numbers in this test indicate better barrier efficiency. Response Medical Surgical Masks earned filtration efficiency ratings well over the 98% required for ASTM Level 2.

Differential Pressure (Delta P)
Differential Pressure or Delta P is a test is performed to determine the breathability of masks by measuring the differential air pressure on either side of the test article using a manometer, at a constant flow rate of 8 L/min. Response Medical masks meet and exceed the less than 6.0 (mm H2O/cm2) requirement with results in most cases under 4.5 (mm H2O/cm2).

This test was performed to evaluate the flammability of our surgical masks by measuring the ease of ignition and the speed of flame spread. The standard requires that a face mask will not ignite and burn for more than 3.5 seconds. Response Medical masks burned for less than one second, meeting and exceeding this requirement.
