"The natural balsa filter will absorb any excess moisture, along with purifying the smoke without restricting the drawing properties of the pipe or affecting the flavor of the tobacco. Replace the insert every 5-6 uses
Filters help you slow down your smoke, as you can smoke very quickly and draw strongly when puffing without one. This in turn helps keep the smoke cooler and allows you to experience more of the tobacco flavor
You can smoke without a filter but due to the physics of air movement, this is not the best idea as a filtered pipe without a filter tends to smoke wet. Circular filters are usually made of wood (balsa or maple), and their primary purpose is to remove excess moisture from the smoke
It is highly recommended to clean the pipe with pipe tools and cotton cleaners between filter replacements to enjoy the true flavor of your choice"
