The Zanxis aquarium descaling filter cartridge is a water-treatment cartridge built around a PET non-woven structure and high-iodine coconut shell activated carbon. It is designed to trap suspended particles that cloud aquarium water, adsorb residual chlorine (Cl2), reduce odours and help limit scale build-up. It fits household and commercial aquarium filters, aquarium water-purification systems and pet automatic water dispensers, and is aimed at aquarium keepers and OEM/ODM buyers who need repeatable water quality.

Before a cartridge is released for production, several values should be fixed and written into the specification. First, confirm the nominal filtration rating and the expected particle-retention performance for the water source in question. Second, agree on the residual chlorine adsorption capacity and the test conditions under which it is measured. Third, define the cartridge dimensions and connection geometry against your filter housing or dispenser socket. Fourth, specify the carbon grade, iodine value and fill weight, because these drive both adsorption life and pressure drop. Fifth, record the recommended service interval and the water volume it assumes. Finally, confirm the compliance documents required for your market. Each of these can be verified with samples and test reports before a purchase order is placed.
The cartridge combines physical interception and adsorption in one body. The PET non-woven structure holds the carbon granules and traps suspended solids that make water look cloudy, while the high-iodine coconut shell activated carbon adsorbs residual chlorine, odours and other dissolved impurities. This combination supports clearer water and helps extend the interval between water changes, which reduces maintenance work for the keeper.
Typical installations are household and commercial aquarium filters, aquarium water-purification systems and the inner core of pet automatic water dispensers. Because the cartridge is intended for periodic replacement, the 2–4 week interval should be treated as a guide: aquariums with a larger volume or a heavier organic load may need more frequent changes, while lightly stocked systems may run longer. The exact interval is best set after observing water clarity and chlorine readings in your own setup.
For OEM/ODM projects, the cartridge can be adapted to customer moulds and dimensions. The 20,000 m² clean workshop supports assembly and packaging in a controlled environment, and the CNAS testing centre provides the data needed for specification sign-off. Customisation options include size, structure, filter media grade, logo and packaging, drawing on more than 1,000 filtration solutions developed by Zanxis.
Zanxis operates a self-built laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment), which can issue test reports for filtration efficiency, dust holding and resistance. Quality control runs through IQC, IPQC and OQC, so incoming materials, in-process assembly and outgoing cartridges are each checked against the agreed specification.
The production base covers 50,000 m², including six clean workshops totalling 20,000 m². The company has held ISO 9001, ISO 14001 and ISO 9001/14001 environmental management certification, and obtained IATF 16949 automotive quality management certification in 2024. Products meet REACH and RoHS requirements, and compliance documents can be supplied. With more than 20 years of filtration research and manufacturing experience and continuous exports to Europe, the United States, Japan and South Korea, Zanxis supports buyers who need documented, repeatable cartridge performance. The address is Zhongshan, Guangdong, China.
To move from specification to sample, please share your device or vehicle model, cartridge size or drawing, required airflow or water flow, operating conditions and estimated quantity. Our team will respond with a precise proposal and the test documentation you need. Contact us to start the sample verification process.
Yes. Zanxis has a CNAS-accredited laboratory that can issue reports covering filtration efficiency, dust holding and resistance. We can provide the report for the parameters you specify, such as residual chlorine adsorption or particle retention. Please tell us which values you need to verify so we can match the test scope.
For custom samples, the engineering team typically completes tooling and sample production within 7–10 working days after the specification is confirmed. Standard samples can be arranged sooner. Validation time on your side depends on your test plan, but most buyers complete fit and flow checks within one to two weeks.
Standard models typically have an MOQ of 3,000–5,000 pieces, while OEM customised models require 5,000–10,000 pieces, depending on specification and packaging complexity. Standard stock orders ship in 7–15 days; custom orders generally take 30–45 days after sample approval. Annual framework agreements are supported for stable supply.
Send the filter or dispenser model, the socket dimensions or a drawing, and the target flow rate. Our engineers will match the cartridge geometry and connection details to your housing. If you have a reference sample, we can work from that as well. A dimensioned drawing is the most reliable starting point.
The suggested replacement interval is 2–4 weeks, depending on aquarium volume and water pollution level. This is a guide rather than a fixed rule; heavily stocked tanks may need more frequent changes. You can verify the interval in your own system by monitoring water clarity and chlorine levels. We can also provide life-test data on request.
The production system conforms to ISO 9001/14001 and IATF 16949 (obtained in 2024). Materials have passed US EPA, NSF and medical supplies GMP standard audits, and products meet REACH and RoHS requirements. Compliance documents can be supplied for your market. Please confirm the specific certificate you need for your region.
Yes. OEM/ODM support covers size, structure, filter media grade, logo and packaging. Our 20,000 m² clean workshop and CNAS testing centre allow us to develop and verify custom specifications. More than 1,000 filtration solutions have been developed, so please share your requirements for a precise proposal.
