Scale no longer builds up inside pipes, boilers, heat exchangers, showers or appliances — reducing energy bills, extending equipment life and maintaining water pressure — all while keeping the natural hardness minerals in the water (no sodium added, safe for low-sodium diets).\u003c\/p\u003e\n\n  \u003cp\u003eThe stainless steel body with 3\/4\" female threaded connections is compact (only 260 mm long), robust (16 bar rated) and features internal stainless swirling elements to ensure effective galvanic action. The zinc anode is consumed over time — simply replace the entire unit after 7 years (no refills, no cleaning). DVGW-certified for potable water safety and trusted across Europe for reliable, zero-maintenance performance.\u003c\/p\u003e\n\n  \u003ch2\u003eWhat Makes the Aquabion H20 Special?\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSalt-Free \u0026amp;
