Why Choose Our Coffee Filter Disc?
This filter disc is engineered to enhance your coffee experience. The 0.3mm aperture ensures that only the finest coffee particles pass through, resulting in a clean cup without sediment while retaining essential oils for a full-bodied flavor. Unlike paper filters that absorb flavor and oils, our stainless steel disc preserves the true taste of your beans. It is also easy to maintain: simply rinse under running water or use a soft brush; periodic boiling helps remove any residue.
For commercial roasters, cafes, and restaurants, our filter disc offers consistent performance and reduces ongoing costs. The robust 304 stainless steel withstands repeated use and high temperatures (up to 300°C), making it suitable for hot water and espresso pressures. Custom sizes are available to fit your specific equipment, ensuring a perfect seal and no bypass.
