This could be the best deal for 50 of level 2 masks with its quality and price for the current market.
The ProShield Duckbill mask is ideal for clinicians who prefer a single pleat design for use during surgical procedures, including those procedures where there is a risk of exposure to body and blood fluids.
Features and Benefits
- Single pleated Duckbill design for easy breathing
- Comfortable hypoallergenic inner liner
- Soft and durable ties
Bacterial Filtration Efficiency (BFE)
- With a Bacterial Filtration Efficiency (BFE) of greater than 99% for media greater than 3 microns, this 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) material filters >99% of particles greater than 0.1 microns. When securely fitted, the 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 mask design provides excellent breathability and low delta P (<=1.8) 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 fluid resistant qualities of the mask provide protection against fluid (120mmHg/16.0kPa) strikethrough.
Fluid resistance is measured in accordance with ASTM F1862-98 & ASTM F1862-00a standard test method for resistance of medical face masks to penetration by synthetic blood at 16.0kPa pressure.
