Lab Report Bacterial Filtration Efficiency & Particle Filtration Efficiency

WHY WE CHOSE TUV SUD TESTING

TÜV SÜD is one of the leading international organizations that offer a third-party's endorsement of products, thus providing an unbiased and objective certification. A trusted partner for safety, security and sustainability solutions, TÜV SÜD is working towards adding value to their partners through comprehensive testing, certification, auditing and advisory services.

As TUV SUD is one of the pioneers in testing the effectiveness of personal protective equipment (PPE), we approached them to audit our collection of protective masks. Here are our results:

 

Particulate Filtration Efficiency (PFE)

Standard: TÜV SÜD PSB certified

 

Our masks were shown to be effective at filtering out particles at 0.1 microns, with an average effectiveness of 99.38% in protecting against the staphylococcus aureus bacteria, also known as “staph.” In other words, our masks were shown to be highly effective in comprehensively filtering and protecting against bacteria.

 

Bacterial Filtration Efficiency (BFE)

Standard: ASTM F2101

 

Our masks were shown to have a BFE of 99.9% after stringent testing using the staphylococcus aureus bacteria, proving them to have effective and comprehensive bacteria filtration.
