Non-woven filter bag
At present, the non-woven filter bags used for filter coffee are patented from Japan. The non-woven filter bags are imported from Japan, such as DIOUS coffee brand filter coffee. The high-quality non-woven filter bag dedicated to filter hanging coffee has no bleaching, fluorescent agent and other residues, uniform density, and is not easy to be damaged when exposed to water. Domestic non-woven materials cannot meet the standards for making premium filter coffee for the time being.
