Featuring a deepened bowl-shaped structure, it conforms to the curvature of most standard coffee pots/filters, making operation more convenient. The widened rim design facilitates even coffee grounds distribution, preventing spillage; the perfectly controlled flow rate fully releases the oils and aromas from the coffee grounds, restoring the true flavor of the coffee beans. At the same time, the bowl shape increases the contact area between the coffee grounds and hot water, resulting in more complete extraction.
