Our coffee machine filter baskets are made from SUS304 food-grade stainless steel, and some high-end models can be upgraded to SUS316L stainless steel. The materials comply with EU LFGB, US FDA, and NSF standards for food contact materials, exhibiting excellent corrosion resistance, high-temperature resistance, and oxidation resistance. They can be in contact with high-temperature coffee liquid and steam for long periods without leaching harmful substances, ensuring the pure flavor of coffee.

We use precision laser etching and electrochemical molding processes, with aperture accuracy controlled within ±0.01mm. The apertures are uniform with smooth, burr-free edges, effectively preventing coffee grounds from remaining and blocking. Each batch of products undergoes flow consistency, aperture distribution, and mechanical strength testing at our nationally accredited CNAS testing center to ensure stable and balanced extraction performance.

Yes. As a manufacturer with over 20 years of R&D experience in filtration products, we can customize the diameter, depth, capacity (single/double/bottomless), aperture specifications (coarse/exquisite), handle structure, and logo laser engraving of filter baskets according to the customer’s coffee machine model. We also provide custom color boxes, blister packaging, and brand labeling services to meet the differentiated needs of brands and OEM clients.

Cleantop has passed ISO 9001, ISO 14001, ISO 45001 certifications and has obtained international certifications including NSF, US EPA, European BSC1, etc. Materials for food contact comply with FDA and LFGB standards. In 2024, we added IATF16949 and medical product GMP certifications, ensuring our overall quality control system covers the entire chain from raw materials to finished products, fully meeting compliance requirements in North American and European markets.

Cleantop's factory in Zhongshan covers an area of 50,000㎡, housing 6 clean workshops totaling 20,000㎡. Coffee machine filtering products are completed with washing, assembly, and packaging in a controlled clean environment to avoid metal shavings and foreign material contamination. We are equipped with a national-level CNAS-accredited testing center, conducting comprehensive testing on key indicators such as aperture, flow, pressure resistance, welding strength, and surface finish. Shipment AQL standards can be executed at customer requirements of 0.65 or stricter levels.

The standard product MOQ is usually 1,000–2,000 PCS; for OEM customized products, it is generally over 5,000 PCS depending on complexity, and new molds need to be developed (taking about 40 days). Sample lead times are 7-10 days, and bulk order lead times are typically 25-35 days. For long-term orders from major clients, we can provide VMI inventory management and rolling production services to ensure supply stability.

Yes, we provide free samples of existing standard specifications (customer pays for shipping). Custom specification samples require a mold or tooling fee, which can be offset after placing a bulk order. All samples include a test report issued by the CNAS testing center for customer material validation and product certification declaration.

Our coffee machine filtering products have been exported in bulk to markets including Europe, the US, Japan, and South Korea, serving well-known home appliance brands, coffee equipment OEM manufacturers, and professional traders. With over 20 years of experience in the filtration industry and over a thousand solution projects, we can respond quickly to different regional certification requirements and technical specifications, providing localized delivery support for customers.
