The VANGUARD Mobile 3 Oral Aerosol Vacuum & Air Purification System is the leader in protecting dental professionals from toxic mercury and harmful aerosols. As contaminated air passes through the VANGUARD Mobile 3, the activated carbon, and HEPA® Filter work in conjunction to capture ultra fine air borne particles and microorganisms, including dust, smoke, allergens, virus, bacteria, mold, gasses, odors, and VOCs, as well as mercury vapors and particulate matter. The unit ships with a 6" hose. The VANGUARD Mobile 3 also has an activated carbon filter which enables the system to be used for the Safe Mercury Amalgam Removal Technique (SMART) to capture harmful mercury vapors and mercury particulate that are released during the removal of amalgam fillings.
