This sintered activated carbon stick is made from high-quality coconut shell activated carbon and food-grade binder through a high-temperature sintering process, providing excellent adsorption performance to effectively remove residual chlorine, odors, discoloration, volatile organic compounds (VOCs), and some heavy metals from water. The typical filtration precision can reach 5 microns, suitable for home/commercial water purifiers, drinking machines, coffee machines, ice machines, and other pre-filter or end-filter scenarios. The service life is generally 6-12 months (depending on the quality and flow rate of the incoming water), and we can provide targeted selection advice based on the customer's actual application conditions.

JND’s water purification products can provide compliance documentation for NSF 42/61 standards, food-grade contact materials from the US FDA, and compliance support documents for EU RoHS/REACH. The company has overall ISO 9001, ISO 14001, and ISO 45001 system certifications, and will obtain IATF16949 and GMP certifications for medical supplies in 2024. We have a national-level CNAS-accredited testing center that can issue authoritative third-party testing reports, ensuring that products meet the regulatory requirements of target markets in Europe, America, Japan, and South Korea.

We support comprehensive OEM/ODM customization services. Customizable items include: outer diameter (Ф) and length size, filtration precision (1/5/10 microns), type of activated carbon (coconut shell/coal), end cap type, center hole diameter, outer membrane coating (PP cotton/non-woven fabric), laser marking/silk screen logo, as well as independent color boxes, neutral packaging, and customer brand packaging, among others. Relying on over 20 years of R&D experience and a thousand solutions accumulated, we can complete sampling within 2-4 weeks.

JND has a factory of 50,000㎡, including six clean workshops totaling 20,000㎡, with key processes produced in controlled environments to avoid secondary pollution. Quality control is ensured through a three-tier quality control system, including IQC incoming inspection, IPQC process inspection, and OQC outgoing inspection. Each batch of products must pass multiple tests, such as flow rate, pressure difference, TOC, particulate retention, and leachables at a CNAS laboratory before shipment, ensuring batch consistency and long-term stability.

The MOQ for standard model sintered activated carbon sticks is typically 1000-2000 pieces, depending on product specifications and packaging requirements; for custom models, the recommended MOQ starts at 5000 pieces. Regarding delivery times, standard products can be shipped within 7-15 days; for OEM custom orders, mass production lead times are generally 25-35 days. We have our own factory in Zhongshan, Guangdong, with flexible production scheduling, and can arrange VMI inventory or batch deliveries for long-term cooperative customers to ensure the stability of your supply chain.

Samples are available for evaluation. Standard specification samples can be provided for free (customers bear international express shipping costs), and for custom specification samples, a reasonable sample fee will be charged depending on development complexity, which can be reimbursed upon bulk order. We can also provide CNAS testing reports, SGS third-party testing data, and application technical support to assist customers in completing product validation and market readiness.

JND was established in 2002 and has been deeply engaged in the filtration industry for over 20 years. Our products have been steadily sold to Europe, the United States, Japan, South Korea, and many other countries, serving globally renowned brands, traders, and OEM customers. We are familiar with the regulatory requirements of various target markets (such as US EPA, NSF, Europe BSC1, etc.) and have a professional foreign trade and technical team that provides comprehensive services from product selection, certification consulting, customized development to after-sales support.
