Hookah Accessory Description Heba Diffusers attach to the bottom of the Hookah Down Stem and are used to break the water into smaller bubbles for increased water filtration, air flow, and an overall calmer Hookah smoking session. The Heba Diffuser Set includes two Diffusers, one small and one large. The small Diffuser is recommended for smaller Hookahs and Hookahs that have a narrow style base. The large Diffuser is recommended for larger Hookahs and Hookahs that have a wider style base.
