The hookah downstem is a vital component of any hookah. It connects the bowl to the main chamber and helps to provide suction, pulling smoke or vapor into the water before it gets inhaled. This long piece of steel can be fixed or removable and can have a diffuser at the chamber end, which additionally cools the smoke. When smoking a hookah, it is important to make sure that the downstem is properly positioned so that the smoke is drawn through the water and cooled effectively. By taking care of your downstem, you can ensure that your hookah smoking experience is always enjoyable.
