They are not cheap dust masks. They are designed for Clinicians/patients to prevent from multiple respiratory diseases.
The ProShield N95 fluid resistant mask provides a high level of respiratory protection for clinicians/patients.
Features and Benefits:
Orange single pleat particulate respirator with bands.
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.
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.
Particulate Filter Respirator
The N-95 mask is NIOSH approved as a N-95 particulate filter respirator. It meets or exceeds the standard performance criteria demanded by NIOSH for the management of Tuberculosis (TB)
NIOSH - National Institute of Occupational Health and Safety (USA).
Fluid Resistance
The fluid resistant qualities of the mask provide protection against fluid 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 (120mmHg).
Not overpriced at all.
