Secure-Gard Standard Surgical Masks,- Secure-Gard surgical masks feature a proprietary construction that makes them among the most comfortable masks available. These masks are engineered with softties for excellent stretch and recovery and a malleable nose wire for a more secure fit. Secure-Bill surgical masks are designed to stand away from the face while providing a secure fit around the nose, cheekbones and mouth. Procedure Masks,- Polypropylene outer-facing/polypropylene inner-facing is the most popular material construction of our procedure face masks due to the flexibility this design provides. It is ideal for patient use and quick application, as it delivers the same level of protection to the wearer if worn correctly or inside out. These masks are also ideal when practicing respiratory etiquette as recommended by the Centers for Disease Control and Prevention (CDC).
