Excellent taste → The coffee filter features a double-layer design made of high-quality 304 stainless steel and an ultra-fine mesh. This allows for optimal extraction time and a rich, full-bodied cup of coffee. No coffee grounds are left in the coffee. Special design → Heat-resistant and non-slip design with a silicone handle for effective heat insulation. The rolled bottom prevents the filter from slipping out of the cup, ensuring a secure and stable fit. Reusable filter → The pour-over coffee filter can be reused multiple times, eliminating the need for filter paper, creating an odor-free experience, and contributing to a more environmentally friendly experience. You don't have to worry about filter paper odor affecting the coffee taste. Less paper, more replanting. Portable → Easy to carry, perfect for home, office, travel, camping, and business trips. The detachable holder fits most cups, mugs, or carafes, including other coffee makers. Easy cleaning → Rinse the inside and outside of the coffee filter under running water in less than a minute. Done. Clean as soon as possible after enjoying your coffee to avoid coffee grounds that may be difficult to remove once dried.
