This coffee machine filter basket is a stainless steel filtration component designed for espresso, drip, and capsule coffee machines. It captures coffee grounds and fines while allowing brewed coffee to pass through, and it is manufactured by Oltaven, a filter specialist based in Zhongshan, Guangdong, China. The basket is made from food-contact stainless steel and is intended for appliance brands, coffee equipment OEMs, and distributors who need a durable, repeatable filtration part.
In a coffee machine filter basket, the “media” is a stainless steel mesh or perforated sheet. The choice of mesh opening, wire diameter, and sheet thickness sets the basic flow and particle retention. But the finished basket is more than the sheet: the forming process—deep drawing, laser etching or electrochemical forming, trimming, and seam welding—determines whether the holes stay uniform and the basket keeps its shape under pressure.
Oltaven supplies finished baskets, not just the mesh. We control the transition from flat material to a three-dimensional basket, so the filtration behaviour you test in a sample is the behaviour you receive in production. That is why two baskets with the same nominal opening can perform differently if their forming and finishing are not controlled.
Three factors decide how a finished basket performs in a coffee machine: the mesh specification, the forming quality, and the assembly and cleaning steps.
Because we make the finished part, we can adjust these variables together. Changing only the mesh without adjusting forming and cleaning can move the result; Oltaven tunes the whole basket to your machine.
The stainless steel coffee machine filter basket is used in semi-automatic and fully automatic espresso machines, American drip coffee makers, capsule coffee machines, and commercial beverage dispensers. In each case, the basket sits in the brewing path and must handle hot coffee and steam without warping or releasing unwanted tastes.
Typical users include coffee machine brands that need a repeatable OEM part, coffee equipment manufacturers that specify the basket as a component, and distributors serving the aftermarket. The basket is also suitable for appliances compatible with major coffee machine brands, but it is an Oltaven-manufactured part, not an original brand component.

Oltaven is built around OEM/ODM capability. We have developed more than 1,000 filtration solutions, and we support custom sizes, structures, filter material grades, frame materials, logos, and packaging. That experience is directly relevant to coffee machine filter baskets, where small dimensional changes affect fit and extraction.
Our plant covers 50,000 m², including six cleanrooms with a combined area of 20,000 m². We operate a CNAS-accredited laboratory that can issue test reports on filtration efficiency, dust holding capacity, and resistance. Our quality system is certified to IATF 16949 (obtained in 2024), ISO 9001, ISO 14001, and ISO 45001, and our products comply with REACH and RoHS environmental regulations, with compliance documents available on request.
With more than 20 years of filtration product development and manufacturing experience, we have exported to Europe, the United States, Japan, and South Korea for over 20 years. Multiple automated production lines support monthly output of millions of pieces, and our quality control covers IQC, IPQC, and OQC. The address is Zhongshan, Guangdong, China.
This workflow keeps the finished filter—not just the mesh—as the unit of control, so what you approve is what you receive.
To quote a coffee machine filter basket, please tell us the device or vehicle model, the size or drawing, the airflow or water flow requirement, the operating conditions (temperature and pressure), and the quantity you expect. With those details we can recommend a mesh and forming approach and prepare a sample plan.
We invite appliance brands, coffee equipment OEMs, and distributors to contact our team to start a custom project. Oltaven supplies finished filters, and we are ready to support your next coffee machine programme.
Resistance depends on the mesh aperture, wire diameter, and how the basket is formed. A finer mesh or a tighter forming tolerance can raise resistance, while a coarser mesh lowers it but may let more fines through. Oltaven controls both mesh and forming so the finished basket meets your flow target.
Forming affects hole uniformity and edge smoothness. When holes are consistent and edges are clean, extraction is more even and fewer fines pass into the cup. Laser etching and electrochemical forming help achieve this, and we clean and pack the baskets in cleanrooms to avoid foreign matter.
Yes. We offer OEM/ODM service and can customise diameter, depth, capacity (single or double shot), aperture specification, handle structure, and logo laser marking. We also provide custom colour boxes, blister packaging, and brand label printing to meet the needs of brand owners and OEM customers.
For standard models, the MOQ is usually 1,000–2,000 pieces. For OEM customised models, it is generally 5,000 pieces or more and requires new tooling development (about 40 days). Sample lead time is 7–10 days, and bulk orders usually ship in 25–35 days.
Yes. We provide free samples of existing standard specifications (customer pays freight). For custom specifications, a tooling or setup fee applies, which can be deducted from the bulk order. All samples come with test reports from our CNAS testing centre for your incoming inspection and product certification.
The basket is a durable stainless steel component, so replacement depends on wear and cleaning regime rather than a fixed interval. We recommend inspecting for deformation, clogging, or damage during routine machine maintenance. For high-volume commercial use, establish a replacement schedule based on your operating conditions.
The basket uses food-grade stainless steel that meets EU LFGB, US FDA, and NSF food-contact material standards. Our quality system is certified to ISO 9001, ISO 14001, ISO 45001, and IATF 16949 (obtained in 2024), and products comply with REACH and RoHS. Compliance documents are available on request.
It starts with your device model, size or drawing, target flow or extraction behaviour, operating conditions, and expected quantity. We review these, propose a basket specification, and produce samples for your evaluation. After sample approval, we confirm the final specification and schedule mass production. Contact us to begin.
