Editor's Pick: This device combines water purification with cold brew functionality, featuring a built-in 6-stage filtration system and a magnesium (Mg²⁺) filter. It effectively reduces chlorine taste, heavy metals, and other impurities that affect flavor, while releasing an optimal amount of magnesium ions to make cold brew coffee smoother, less acidic and bitter, with a more pronounced coffee aroma. The brewing process is simple: just add coffee grounds, pour in water, and refrigerate for 12-24 hours to enjoy café-quality iced coffee at home. It's not only great for cold brew coffee but also perfect for cold-brewed tea, lemonade, fruit drinks, and more—one pitcher meets all your summer beverage needs.
