ABSTRACT:
A filter device comprises a clear plastic cylinder member with a pair of ends each bearing fittings conditioned to connect to an existing air supply line. At least one of the fittings bears a quick-release feature enabling ready access to that end of the cylinder member. The cylinder provides a housing for one or more standard cotton rolls, such as those typically used in a dental office, which provide the filtering medium. Thus, dental office personnel can visibly monitor the cotton rolls through the clear cylinder member, enabling easy viewing of the impurities captured by the cotton rolls, and determination of when replacement of the cotton rolls is necessary.
