<p>A combination air and water micro-filtration device (102) suitable for mounting on a dental syringe handset (100) contains microporous membrane air and water filters (213, 219) 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.</p> |
