The Savinelli Balsa System is a filtering system using the natural attributes of balsa wood.
It allows the absorption of both moisture and impurities from smoke, without the addition of chemical elements, insuring a clean pipe shank.
This absorption ability is due to the extremely porous fibres of the balsa, which allows for a perfect smoke without altering the flavour and aroma of the tobacco.
It is advisable to replace it every two / three smokes, or every time you clean the pipe.
It is also recommended not to let the pipe sit longer than one day with a used filter inserted.
