Our sintered activated carbon rods are made from high-quality coconut shell activated carbon and food-grade binders that are sintered at high temperatures, offering excellent adsorption capability and filtration precision (usually 5-10 microns), effectively removing residual chlorine, odors, organics, VOCs, and some heavy metals. The compact Ф32*126 size is widely suitable for countertop water purifiers, pre-filters, bottled water dispensers, as well as prior to the RO reverse osmosis systems and in commercial coffee machines and ice makers. Cleantop possesses a CNAS approved testing center, providing customers with complete filtration performance test reports.

Our sintered activated carbon rod raw materials meet food safety standards and have been certified by authorities such as NSF, the US EPA, and SGS, as well as holding the relevant BSC1 certificates in Europe, fully complying with the regulatory requirements for major export markets in the EU, USA, Japan, and South Korea. The company is also certified by ISO 9001/14001/45001, and has newly obtained IATF16949 and medical supplies GMP certification in 2024, providing complete compliance documentation support for brand owners and traders.

We fully support OEM/ODM customization services, which is one of Cleantop's core advantages. The customizable options include: dimensions (outer diameter, inner diameter, length), filtration precision (0.5-20 microns), types of activated carbon (coconut shell carbon/coal-based carbon/fruit shell carbon), weight and density, end cap structure, addition of functional media (such as KDF, lead removal, antibacterial silver ions, etc.), as well as brand logo printing, independent packaging, and design of color boxes and instruction manuals. With over 20 years of experience in the filtration industry and thousands of solutions accumulated, we can quickly respond to customers' personalized needs.

Cleantop's factory covers an area of 50,000㎡, including six clean workshops totaling 20,000㎡, where the sintered activated carbon rod products are produced in a controlled clean environment, effectively avoiding cross-contamination. We are equipped with a nationally recognized CNAS testing center capable of conducting flow tests, pressure differential tests, dust holding capacity tests, particulate matter retention tests, TOC and heavy metal leach tests, and other full-scale testing. Every batch of products undergoes a three-tier quality control process consisting of IQC incoming inspection, IPQC process inspection, and OQC outgoing inspection to ensure stable and reliable quality.

The standard Ф32*126 sintered activated carbon rod is recommended for a service life of 6-12 months or a treated water volume of approximately 2000-4000 liters under regular municipal tap water conditions (TDS<500ppm, residual chlorine<2ppm), depending on the quality of the inflow water and usage flow rates. For high-frequency use scenarios such as commercial coffee machines and ice makers, it is advised to replace based on actual treated water volume. We can provide customized lifespan testing and usage cycle suggestion reports based on the water quality conditions of your target market.

The MOQ for standard models of sintered activated carbon rods is typically 1000-2000 pieces, depending on the product specifications and packaging requirements; the suggested MOQ for custom models is 5000 pieces or more. In terms of delivery timelines, standard products in stock can be shipped within 7-15 days; the production lead 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 staggered delivery for long-term partners to ensure your supply chain stability.

Sintered activated carbon rods are handled with dust removal treatments in clean workshops before leaving the factory, packaged in food-grade PE bags either vacuum-sealed or heat-sealed, and then placed in moisture-proof cartons, with pearl cotton or EPE layers inside to prevent compression damage. The outer boxes can be printed with brand information, barcodes, and export marks per customer requests. For long-distance sea transportation, we provide moisture-proof and mold-proof treatment solutions to ensure the products arrive in the customer's warehouse in a clean state and intact structure.
