The design with carefully placed perforated holes ensures perfect and uniform water flow. There are a total of 98 holes, each with a diameter of 3 mm, with 19 micro-perforated holes each. This provides uniform water distribution, essential for the proper extraction process. Additionally, the Teflon coating improves water flow and reduces dirt buildup. The extraction head is made from a single piece of material and features a smooth surface that prevents clogging.
