Vauen pipe filters are 9mm in diameter. Inside this paper filter there is a carbon filtration system. According to many this is the best form of filter. The carbon takes away an emphatic amount of moisture away from the smoke and it removes much more tar than other filters.

A filter is a pretty simple thing. They keep 'stuff' from passing. The filter keeps spittle from your mouth from settling in the bowl. It trap tars, nicotine, and debris from the bowl to your mouth. This filter does a good job of doing that. There are only two things to consider. The filter also reduces flavor so you may need to use a different tobacco for a filtered pipe. How often you change the filter will depend on how wet it gets, either from your tobacco or from your mouth.
I have used these filters in my Molina 9mm pipes and I am very satisfied with the performance.
I bought a few pipe filters for a freinds birthday. Came in great time and in good shape. Probably a good product it has the most stars.
