We even use filtered water for our coffee. We’re hooked on this Zero Water system and it’s working great for us for all of our drinking water (we have one in the fridge) and the water for our coffee. It helps prevent limescale buildup in appliances such as kettles and coffee makers, potentially extending their lifespan. Using filtered water can improve the taste of coffee and tea by eliminating metals, salts, and minerals that may cause a metallic taste in these beverages. ZeroWater is a water filtration brand renowned for its advanced 5-stage filtration system, designed to remove virtually in total dissolved solids (TDS) from tap water, resulting in pure and clean drinking water. Stay healthy and active and drink water! We keep one in the fridge and one on the counter. The filters seem to last awhile but that depends on your water LTKHome LTKActive
