The 6mm Falcon pipe filters are made of wood cellulose. They work by absorbing condensation from the mouth, as well as tar and nicotine from the pipe bowl. These filters can be used in other 6mm tobacco pipes (like corn cobs and Savinelli pipes). Using one of these filters in the convertible systems produces a duel dry system, for the cleanest smoke possible.

They seem to mellow the smoke. No bite.
