Roor Diffuser downstem is the perfect addition to any waterpipe. It breaks up the smoke into loads of bubbles allowing for more filtration and hence a smoother smoke than using a normal downstem.

Contrary to conventional down tubes, the opening of the tube's end is first sealed and then pierced with small holes. This means better distribution of the smoke as it rises in many small bubbles, which is the basis for its typical character. The option diffuser is most suited for those who prefer a mild smoking experience.
