I like the balsa system and it is the only filter system that I do like. Having said that I agree it is not really a filter.
I only have 1 Savinelli and it is the very definitely full bent. Shape 614. When using the balsa filter I have never once needed to pass a cleaner through. It has never ever gurgled on me with the filter. It has with the adapter but never with the filter so I have to say that it does its job very well. If yours did gurgle then perhaps you are correct in thinking that there was moisture in there before you put the knew filter in. I always clean mine after each smoke. Who knows though. I have learned that pipes can be funny things.
the filter has the ability to absorb 77% of the nicotine and 91% of the tar contained in tobacco
To that I have to say cobblers. Sure it must suck up some but not anywhere close to that figure. I simply don't believe it. I never notice my blends weaker in either departments when using the filter. The only thing it does for me is suck up that annoying moisture. If it was sucking up all my nicotine I would not be a happy chappy and that is for sure.
I do reuse them but I won't leave them in the pipe. They just make it smelly and damp in there so I take them out to dry and I clean my pipe. Once dry I will use them again. I do this perhaps 3 times then chuck them. I never notice them change the flavour with this practice neither do I taste balsa when I insert a new one as some have mentioned.
Of course this is just my use and experience with them and perhaps I don't notice a bad taste from them on the second or third use of the filter because I have a mouth like a rubbish skip. I can tell you this though. I hate a sour pipe. I like them clean and I tend to notice right away if something is slightly askew with my pipes flavour. At lease I think I do :wink:
I would not hesitate to buy another Sav filter pipe. I like the choice they give you and if my one and only Sav is anything to go by, the standard of engineering and smoking qualities of them for the price is excellent. It smokes just as well as some of my more expensive pipes and even better in some cases if I am to be honest. Now I think about it I don't know why I don't have more.
I will not however buy any other type of filter pipe. I just don't like them.
