UNITED STATES - May 5, 2020: In full PPE gear Dr. Marcus Hoang, DDS and assistant Fariba Safaei of The Dental Co. of Leesburg work with a patent using the new vent called the Dental Pro Plus with Microbiological and Mercury FlexKit Kit. This air filter will not only filter out coronavirus ( microns) but will filter down to microns. What makes this filter different than others is it is made from "Non-woven Glass media". They are good in up to 95% humidity. The air flowing through the filters also dries the aerosols quickly. (Photo By Douglas Graham)
