All devices use the same high-efficiency, electrostatic filtration media. The filter media has been tested by independent labs to meet the following criteria:
| NaCl Penetration at 32 LPM | < 0.10% | Tested in accordance to TSI8130 NaCl 0.1 micron particle size |
| NaCl Efficiency at 32 LPM | > 99.90% | Tested in accordance to TSI8130 NaCl 0.1 micron particle size |
| Pressure Drop at 32 LPM | < 2.3 mm H2O | Tested in accordance to TSI8130 NaCl 0.1 micron particle size |
| Air Permeability | > 85 CFM | Tested in accordance to ASTM Spec ASTM D373 |
| Bacterial Filteration Efficiency | > 99.99990% | Tested in accordance to Spec MIL-M-36954C By Nelson Labs |
| Viral Filtration Efficiency | > 99.99975% | Tested in accordance to Spec MIL-M-36954C by Nelson Labs |
