Frequently Asked Questions (FAQ):
Q1: Is this filter disc compatible with all espresso machines?
A: The 20mm diameter is designed to fit most standard 51mm and 58mm portafilter baskets when used as a bottom filter. However, we recommend measuring your basket's internal diameter to confirm compatibility. Custom sizes are available upon request.
Q2: How do I clean the filter disc?
A: After use, rinse the disc under warm water and gently brush off coffee grounds. For deeper cleaning, soak in a solution of mild detergent and water, then rinse thoroughly. Avoid using abrasive scrubbers that may damage the mesh.
Q3: How many times can I reuse this filter?
A: With proper care, the 304 stainless steel disc can be reused hundreds of times. Replace it if you notice any deformation or clogging that cannot be cleaned.
Q4: Does the 100 micron mesh affect the taste of espresso?
A: 100 micron is a well-balanced mesh size that allows adequate flow while preventing coarse grounds from passing through. It helps produce a clean cup with good body and crema, similar to a paper filter but with more oils retained.
Q5: Is this product food-safe?
A: Yes, 304 stainless steel is a food-grade material commonly used in kitchenware and coffee equipment. It is non-toxic, rust-resistant, and safe for contact with hot beverages.
Q6: Can I get a different diameter or thickness?
A: Absolutely. We offer customization on diameter (from 15mm to 100mm) and thickness (0.3mm to 1.0mm). Minimum order quantities may apply for custom sizes. Please contact us with your requirements.
