Savinelli 6MM Balsa Filters

The pipe filter made of balsa wood: Balsa is a very soft wood, with porous fibers that have absorbent properties. Balsa filters are therefore 100% natural. They absorb moisture, as well as some of the harmful substances in tobacco. Moreover, the filter does not fill in all the stem when in place, therefore the air flow is not impeded when smoking.  How to use this 6mm balsa filter?  6mm balsa filters can be used with any pipe bored with a 6mm-diameter. There is no need to put it on in a specific way, you just have to place it in the tenon. The filter needs to be changed after 2 to 3 pipes. Of course, this depends on the size of the bowl and the tobacco. Therefore, some smokers might prefer replacing it more often.
