304 STAINLESS STEEL - Our ultra-fine mesh is made of heavy-duty stainless steel, and its premium quality ensures it won't rust and lasts longer than ordinary tea and coffee filters. SUITABLE SIZE - Our French press replacement filters (4 inches in diameter, 5/16 inch hole) are designed to fit most coffee press models. EASY TO CLEAN - Rinse your French press coffee filter under the tap for a few seconds and immediately benefit from no coffee grounds left behind. HIGH FILTRATION QUALITY - These filters use a fine mesh with 100 threads per inch, which is far superior to other generic mesh filters on the market. This feature allows you to enjoy more highly filtered, flavorful cups of coffee or tea with every brew in your French press. We recommend replacing your coffee filter parts regularly for the freshest beverages. METAL RING - Unique reinforced center ring prevents fraying and ensures long life.
