Abstract
A combination air and water microfiltration device suitable for mounting on a dental syringe handset contains microporous membrane air and water filters which prevent particulate and bacterial contamination of the air and water streams applied to a dental patient's oral cavity during dental procedures. The small pore size of the microporous membrane allows filtration of infectious agents while maintaining adequate flow rates.
