Which ASTM level mask provides the protection I need when using ultrasonics?
An ASTM level 2 mask would be appropriate if moderate to light amounts of fluid, spray, and/or aerosols are produced. As ultrasonic and air polishing procedures may take 20 minutes or more, consider wearing an ASTM level 3 mask if moderate to heavy amounts of fluid, spray, and/or aerosols are produced such as with ultrasonics or air polishing.
