Stainless Steel Mesh Coffee Filter

Stainless Steel Mesh Coffee Filter

Anping CREMOTIVE Wire Mesh Products CO., LTD introduces its Stainless Steel Mesh Coffee Filter, engineered to combine durable construction with precision filtration for coffee brewing systems ranging from commercial espresso machines to pour‑over drippers. Crafted from food‑grade 316L stainless steel wire mesh, these filters deliver consistent extraction by trapping grounds and oils while allowing natural coffee oils and fine particulates to pass, resulting in a balanced flavor profile and reduced paper‑filter waste.

Construction & Materials
The core of each filter is a single layer—or, for finer filtration, multiple nested layers—of woven stainless steel mesh. We employ a plain‑weave pattern using 0.10 mm warp and weft wires to achieve mesh openings of approximately 80 µm. This aperture size captures ground particles larger than micro‑fines while allowing solubles and desirable micro‑oils to flow through. The mesh is sintered to a rigid ring or disc shape, ensuring the filter holds its geometry under brewing pressures up to 9 bar in espresso applications and maintains flatness in gravity‑drip setups.

Design Features

• O‑Ring Seal Grooves: Machined into the filter rim, these grooves accommodate silicone or Viton seals for leak‑free integration with portafilters or filter holders.

• Custom Diameters: Standard sizes range from 58 mm for E61 portafilters up to 80 mm for commercial group heads, with bespoke diameters and thicknesses available on request.

• Surface Finish: Electropolished to Ra ≤ 0.4 µm, the filter surface resists scale and oil residue build‑up, simplifying cleaning and preserving taste integrity.

Brewing Performance
In espresso use, the stainless steel mesh filter ensures uniform water distribution across the puck while capturing fines that can contribute to clogging and channeling. In pour‑over drippers, the filter promotes a fuller mouthfeel by retaining soluble oils and micro‑particles that paper filters normally remove. The result is a richer‑bodied cup with enhanced aroma and crema retention.

Maintenance & Longevity
Unlike disposable paper or cloth filters, stainless steel mesh filters endure thousands of cycles. Daily cleaning involves back‑flushing with warm water or detergent; deeper cleaning uses ultrasonic baths or mild acid soaks to remove mineral deposits. Electropolished finishes facilitate rapid drying and prevent bacterial growth. Typical service life exceeds five years under normal café or home‑use conditions.

Customization & Quality Control
Anping CREMOTIVE’s in‑house machining and weaving lines support rapid prototyping and volume production. Each batch of mesh filters undergoes dimensional inspection (diameter, thickness, aperture consistency) and flow‑rate testing to ensure performance meets specifications. Food‑contact compliance documentation is provided with every shipment.
