Surgical Mask Ratings

All our masks conforms to the updated Australian Standard 4381:2015 with the update of “resistance to penetration to blood by synthetic blood (fluid resistance) min pressure” which is to be a value of mmHg.

Our Level 2 and Level 3 Surgical Masks have an exceptional BFE rating of 99.9% where the performance required for these level is 98%

Level 1

Applications: 
For general purpose medical procedures, where the wearer is not at risk of blood or bodily fluid splash or to protect staff and/or the patient from droplet exposure to microorganisms (e.g. patient with upper respiratory tract infection visits GP)

Bacterial Filtration Efficiency (BFE):
> 95%

Particulate Filtration Efficiency (PFE) % (0.1um):
Not Required

Differential Pressure (Delta P) mm H2O/cm2:
< 4.0

Resistance to penetration by synthetic blood (fluid resistance) min pressure in mm Hg for pass result:
80mm Hg

Level 2

Applications: 
For use in emergency departments, dentistry, changing dressings on small or healing wounds where minimal blood droplets exposure may possibly occur (e.g. endoscopy procedures)

Bacterial Filtration Efficiency (BFE):
> 99.9%

Particulate Filtration Efficiency (PFE) % (0.1um):
Not Required

Differential Pressure (Delta P) mm H2O/cm2:
< 5.0

Resistance to penetration by synthetic blood (fluid resistance) min pressure in mm Hg for pass result:
120mm Hg

Level 3

Applications: 
For all surgical procedure, major trauma first aid or in any area where the health care worker is at risk of blood or bodily fluid splash (e.g. orthopaedic, cardiovasular procedures)

Bacterial Filtration Efficiency (BFE):
> 99.9%

Particulate Filtration Efficiency (PFE) % (0.1um):
Not Required

Differential Pressure (Delta P) mm H2O/cm2:
< 5.0

Resistance to penetration by synthetic blood (fluid resistance) min pressure in mm Hg for pass result: 

160mm Hg
