Valvo Matic Filter

Length: 36 mm
Diameter: 9 mm
Method: Silica gel + elastic valve

This filter combines an elastic valve with the silica gel for specifically trapping tar.  By breathing in the  smoke, the smoker opens the valve, thereby creating a very thin slot that ensures most of the tar is deposited on the filter wall. The silica gel then completes the filtering operation.
