The porous PTFE membrane is advertised to provide a low pressure drop particulate filter with a minimum 98% particulate efficiency. The secondary filter particulate media is made from a durable hydrophobic polytetrafluoroethylene membrane which is water repellant and can therefore can be disinfected. The main facepiece itself also utilizes a self regulating twin seal design that is promoted by the manufacturer to maximum protection against inward leakage.

The report was issued in 2017 and finding can be reviewed within the reference section ģM/Scott confirmed that the FRR has now been discontinued from their range of products Overview Facepiece The assessment addressed 25 evaluation criteria in 5 SAVER categories: Affordability, Capability, Deployment, Maintainability, and usability. The assessment was undertook by emergency responders with the criteria and scenarios used in the assessments were derived from the results of a focus group of emergency responders with experience using CBRN APRs. This program funded by the US Department of Homeland Security (DHS) aims to assist emergency responders making procurement decisions.
