Follow CDC guidance and OSHA mandates based on current risks for disease transmission. In general, use Level 1 and 2 masks for exams and other procedures not likely to produce aerosols or spray, or for patients and visitors. Use a Level 3 mask like Shield for procedures likely to generate aerosols when an N95 level…

Yes, medical masks are tested at certified 3rd party labs using the ASTM Performance Rating method (ASTM F2100-11). Ratings range from Level 1 – lower fluid resistance to Level 3 – highest fluid resistance. Our Shield High-Efficiency Face Mask is rated level 3.

Our Shield High-Efficiency Face Mask is rated ASTM Level 3, the best protection short of N95 respirator masks. Level 3 masks are recommended for a wide range of procedures including those likely to generate aerosols and spray (in the absence of requirements for N95 level protection).

In addition to the Level 3 filtration efficiency and fluid resistance, Shield masks are designed with Positive Facial Lock® and Twist Seal® to allow a custom fit around the nose, sides and chin. This reduces leakage and “blow-by” of particles and aerosols around the edges of the mask during procedures.

The Shield High-Efficiency Face Mask combines comfort with customized fit, all without OSHA fit test requirements. This mask is constructed with soft hypoallergenic materials and no latex components. Magic Arch® lifts the mask material slightly away from nose and skin to slow down saturation and improve overall breathability.

Disposable masks, including the Shield High-Efficiency Face Mask, should be changed when visibly soiled, wet and between patients. Procedures that produce high aerosols (use of high-speed handpieces and powered ultrasonic scaling devices) may require changing the mask several times during a procedure on a single patient.
