The Flat Bottom Coffee Filter is a food-grade filter paper designed specifically for flat-bottom drippers, flat-bottom coffee machines, and commercial brewing systems. Crafted from high-quality fibers, the filter features a stable structure, excellent permeability, and uniform filtration performance; it effectively separates brewed coffee from grounds and minimizes the passage of fine particles into the cup, resulting in a clearer, cleaner brew.
Available in both white and natural (unbleached) options, the filter caters to diverse brand requirements regarding aesthetics, eco-friendly branding, and product positioning. With its uniform fiber distribution and stable pore structure, the filter ensures an optimal flow rate while effectively retaining coffee grounds, making it suitable for a wide range of settings-including specialty coffee shops, chain cafes, hotels, the foodservice industry, coffee roasters, and home pour-over brewing.
Key Features
