Matrix Percolator

A popular design is the matrix percolator, which uses a mix of horizontal and vertical slits, similar to the honeycomb and showerhead design. These percs are usually made of slim discs stacked near the base on the bong. As smoke passes through, it is forced to churn in order to push through the many slits, creating strong diffusion.

These percs are known for producing some of the best filtration on the market. The intense churning creates a high volume of bubbles that deliver a silky smooth pull, and the bubbling action also puts on quite a show, which makes it a favourite for those looking for aesthetics from their perc.
