Description
BACTERIAL FILTRATION EFFICIENCY (BFE)
- With a Bacterial Filtration Efficiency (BFE) of greater than 99% for media greater than 3 microns, this Proshield face mask provides superior protection from potential infection.
BFE is an independent test conducted by Nelson Laboratories that measures the effectiveness of face mask materials to filter out bacteria.
PARTICULATE FILTRATION EFFICIENCY (PFE)
- The super high Particulate Filtration Efficiency (PFE) of the Proshield face mask material filters >99% of particles greater than 0.1 microns. When securely fitted, the Proshield face mask helps to provide an effective barrier to particulate matter from laser plumes and electrocautery procedures.
PFE measures effectiveness of the mask material to filter particulate matter.
BREATHABILITY (DELTA P)
- The Proshield face mask design provides excellent breathability and low delta P (≤1.4) ensuring coolness and comfort even when worn for an extended period.>
Delta P, also conducted by Nelson Laboratories, is a test that measures the breathability of mask materials, ranking masks on comfort and coolness for the surgical mask wearer. The lower the figure, the cooler and more comfortable the mask.
FLUID RESISTANCE
- The Proshield Proshield face mask provides a fluid resistance of 80 mmHg and is ideal to be used in medical procedures where the wearer is not at risk of blood or of bodily fluid splash.
High filtration surgical mask with ties
Areas of use
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).
