Our Ф40*195 sintered activated carbon stick is made of high-quality coconut shell activated carbon formed through a high-temperature sintering process, featuring high adsorption capacity and a stable filtering structure. The main performance indicators include: effective removal of residual chlorinated compounds (removal rate ≥ 95%), odors, colors, VOCs, and organic pollutants, with a filtering precision of up to 5 microns, effectively intercepting particulate impurities. Typical lifespan is 6-12 months (depending on water quality and flow rate). This product is widely used in household water purifiers, commercial drinking machines, pre-filtering systems, and front/back filtering stages of RO reverse osmosis systems, making it an ideal filter for brands to build household and commercial water purification products.

As a professional filtering company established in 2002, we have passed ISO 9001, 14001, 45001 system certifications, and have obtained international authoritative certifications such as NSF, EPA, BSC1, and SOP. We also achieved IATF16949 and medical product GMP certification in 2024. Our products are consistently exported to multiple countries including Europe, the USA, Japan, and South Korea, fully meeting compliance requirements for the markets of Europe, America, and Japan, and can provide complete certification document support for your export business.

We have strong OEM/ODM customization capabilities. With over 20 years of R&D experience and thousands of filtering solutions, we can provide customers with: 1) Size customization — diameter, length, inner and outer diameters can be adjusted as needed; 2) Performance customization — activated carbon mesh, pore size, and ratio of adsorption mediums (such as adding KDF, ion exchange resin, etc.), 3) End cover structure customization — matching different brand water purifier interfaces; 4) Packaging customization — independent packaging, brand LOGO printing, label and color box design. We welcome you to provide drawings or samples, and our engineering team will collaborate throughout the sampling process.

Our factory covers an area of 50,000㎡ and includes 20,000㎡ of six clean workshops, ensuring a production environment free from cross-contamination. Key advantages in quality assurance include: 1) National-level CNAS recognized testing center capable of independently conducting a full range of performance tests such as flow rate, pressure drop, residual chlorine removal rate, TOC, and particulate interception rate; 2) Strict IQC incoming inspection → IPQC process inspection → OQC outgoing inspection three-tier quality control process; 3) Samples from each batch are retained and COA test reports are issued; 4) ISO 9001 and IATF16949 quality management systems ensure product batch consistency with a defect rate controlled at an industry-leading level.

The MOQ for standard model sintered activated carbon rods is typically 1000-2000 units, depending on product specifications and packaging requirements; for customized models, the MOQ is recommended to start at 5000 units. Regarding delivery times, standard products in stock can be shipped within 7-15 days; the mass production delivery time for OEM custom orders is generally 25-35 days. We have our own factory in Zhongshan, Guangdong, with flexible production scheduling, and can arrange VMI inventory or split deliveries for long-term cooperation customers to ensure stable supply chains.

Yes, we welcome customers to request samples for testing. Standard specification samples can usually be sent out for free within 3-5 working days (sample fees depend on quantity, shipping costs are generally borne by the customer); the development cycle for customized specification samples is approximately 10-15 working days. Samples come with a complete performance testing report issued by a CNAS laboratory, facilitating customers' performance validation and market evaluation. If customers have specific testing standards (such as NSF/ANSI 42, 58), we can also assist in completing targeted tests.

Compared with traditional compressed activated carbon (CTO) filter elements, sintered activated carbon rods have significant advantages in B2B brand applications: 1) Dense and uniform structure, no channel flow effect, higher adsorption contact efficiency; 2) Dual functionality of filtering precision (5-micron level) and deep adsorption, can replace the combination of PP + CTO; 3) No adhesives or use of food-grade UHMWPE adhesives, resulting in purer water quality without TOC leaching; 4) High mechanical strength, stable operating pressure drop, and minimal powder shedding; 5) Lifespan is 30%-50% longer than traditional CTOs. They are very suitable for mid-to-high-end water purifier brands to enhance product competitiveness.

All raw materials for our sintered activated carbon rods meet safety standards for food-grade and drinking water contact materials. The core activated carbon is made from high-quality coconut shell carbon, certified by NSF 42 standard; the binding material is food-grade UHMWPE (FDA compliant); end cover materials are food-grade PP or ABS. Each batch of raw materials is subjected to heavy metal leaching, TOC leaching, microbiological and other testing by a CNAS laboratory, ensuring compliance with drinking water safety regulations in the USA (NSF/ANSI 42/61), EU REACH, RoHS, and China GB/T 5750 among others.
