1. High quality materials: This coffee filter is made of 304A food grade stainless steel and filtered with 800 mesh ultra-fine mesh. The extraction time is controlled reasonably to achieve the extraction rate. 2. Environmental protection and hygiene: Traditional disposable coffee filter paper is not only expensive but can only be used once. Using our reusable hand brewed coffee filter is not only convenient to use but also environmentally friendly. 3. Easy to carry: We adopt a detachable design, and the filter and bracket can be separated, even if you are traveling or camping. They can all be carried with you, and our stand is suitable for the vast majority of cups, mugs, or water bottles, allowing you to easily complete handmade coffee making. 4. Easy to clean: Our stainless steel coffee filter can be easily rinsed and dried with water, or placed in the dishwasher. After enjoying the coffee, please clean it as soon as possible to avoid difficulty cleaning the coffee grounds after drying.
