A showerhead percolator is a specialized diffusion device used in water pipes and dab rigs to filter and cool smoke before inhalation. It consists of a vertical glass tube with a flared bottom containing multiple small slits or holes in a circular pattern, resembling a showerhead. As smoke passes through the openings, it creates smooth, steady bubbles. By breaking up smoke into tinier particles, showerhead percolators enable optimal cooling, filtration and full flavor. The greater diffusion also produces a smoother hit that expands lung capacity, allowing consumers to take bigger rips comfortably. The scientific glass construction makes showerhead percs durable and easy to clean. They deliver excellent percolation on their own and also stack well with other percs for multiplied diffusion. Overall, a quality showerhead perc delivers cool, smooth, filtered hits that highlight the nuanced aromas and flavors of different cannabis strains.
