Showerhead percolators are glass filters made with slits for airflow placed at the bottom of a vertical tube that flares at the bottom. This creates bubbles that diffuse and filter the smoke or vapor as it passed through the percolation filters. The actual tree percolator inside the dab rig is a tube that goes up through the middle, that tube attaches to a bunch of arms up high, and those arms descend from that attachment point into the water, resembling the branches of a tree. The Showerhead Tree Perc dab rigs come with these perc features and are made of clear and colored thick glass. Standing at just 10 inches tall this piece of functional glass art is made for concentrates.
