About This Coffee filter paper separates grounds and liquid: It blocks coffee grounds from mixing with liquid, allowing only the extract to flow through, providing a basic filtration condition for drip coffee preparation. Drip filter paper: Guides water to seep through, making hot water evenly pass through the coffee grounds, naturally releasing flavor substances, suitable for manual pour-over and drip machine brewing methods. Pour-over filter paper: Holds the coffee grounds, providing a stable space for them, used with a filter cup, forming a standardized structure for manual pour-over coffee preparation. Filter paper: Reduces residue retention, blocks fine particles from entering the cup, decreases sediment at the bottom of the cup, making the coffee drinking experience cleaner. Coffee filter sheets: Compatible with various filter cups, can be paired with cone-shaped, fan-shaped, and other types of filter cups, meeting the usage scenarios of multiple manual brewing tools.
