In 1981, after several years of research, Savinelli launched the “Dry System”, combining trap and filter.

The name “Dry” comes from the introduction of the balsa “filter” into the traditional system pipe - the “System” being the presence of the built-in moisture trap in the shank.

The balsa mops up the moisture in the smoke hence the term “Dry” system, and if the pipe is smoked without the balsa all that will happen is that this moisture will condense and collect in the trap.

It can then either be mopped up with a folded pipe cleaner, or flicked out.
