Our sintered activated carbon rods are made from high-quality coconut shell activated carbon and food-grade binders, sintered at high temperatures, featuring a uniform and dense pore structure that efficiently removes residual chlorine (removal rate ≥95%), odors, discoloration, VOCs, and organic materials from water. Additionally, the sintered structure has a mechanical filtration precision of ≥5 microns, capable of intercepting particulate impurities such as sand and rust. The standard specification Ф60*240 is suitable for household and commercial water purifiers, countertop water machines, and end-point drinking devices, with a lifespan of 6-12 months under standard flow (dependent on water quality).

Our sintered activated carbon rods have been certified by NSF 42 for drinking water treatment and relevant testing by the US EPA, with all raw materials being food-grade, compliant with drinking water contact material safety standards. The company also holds ISO 9001, ISO 14001, and ISO 45001 certifications, and will obtain IATF 16949 and GMP certification for medical supplies in 2024, fully meeting the stringent compliance requirements for drinking water products in high-end markets in Europe, the US, Japan, and Korea.

Yes. As a manufacturer with over 20 years of experience in the filtration industry, we can customize the following based on customer requirements: 1) Size specifications (diameter, length, center hole diameter); 2) Filtration precision (1-20 microns available); 3) Type of activated carbon (coconut shell carbon, coal-based carbon, fruit shell carbon, etc.); 4) Functional upgrades (KDF composites, lead removal, antibacterial silver ions, etc.); 5) End cap structure and interfaces; 6) Independent packaging and brand logo printing. We have thousands of mature filtration solutions in stock and can quickly respond to customer customization needs.

Cleantop is located in Zhongshan City, with a factory area of 50,000㎡, including a clean workshop of 20,000㎡ (6 independent clean rooms), strictly controlling the production environment of sintered activated carbon rods to avoid secondary pollution. We have a national-level CNAS accredited testing center that conducts full testing on each batch of products for flow rate, pressure difference, filtration precision, residual chlorine removal rate, TOC leaching, heavy metals, etc. Along with the IATF 16949 automotive quality management process, we ensure batch stability and high consistency of products.

The minimum order quantity (MOQ) for standard Ф60*240 sintered activated carbon rods is typically 1000-2000 pieces; the MOQ for customized products can be negotiated based on specification complexity. Regular stock products are shipped within 7-15 days; OEM customized orders generally take 25-35 days (including mold confirmation and sampling). Our large-scale production capacity layout in Zhongshan, Guangdong, ensures stable bulk supply for large clients in Europe and the United States, with flexibility to adjust during peak seasons.

Yes. We welcome customers to request samples for testing; standard specification samples can be quickly provided, usually sent out within 3-5 working days. Custom samples based on specific parameters take 7-15 days to develop. Samples will be accompanied by a test report issued by a CNAS laboratory (including key data such as filtration efficiency, residual chlorine removal rate, flow rate pressure difference, etc.), facilitating technical evaluation and market validation for customers.

The standard export packaging consists of independent PE shrink film or vacuum bag + color box + outer carton, effectively moisture-proof and dust-proof, ensuring product cleanliness. We support comprehensive packaging customization, including customer brand color box design, instruction manuals, barcodes, and QR code traceability labels. All packaging materials comply with EU REACH and food contact material regulations, ensuring product quality stability during long-distance sea transportation.

Cleantop was established in 2002, and its products have been consistently sold to various countries and regions such as Europe, the United States, Japan, and South Korea, serving numerous internationally renowned water purification brands and OEM customers. We hold multiple overseas certifications including European BSC1, US EPA, NSF, and SOP, and are familiar with the regulatory requirements and quality control standards of the European and American markets. After signing a non-disclosure agreement (NDA), we can provide similar cooperation cases and reference client information, and welcome further communication.
