This sintered activated carbon rod, model Ф60×240, is a replacement filter element for water purifiers and refrigerators. It combines high-iodine coconut shell activated carbon with food-grade ion exchange resin to reduce chlorine, odors, discoloration, and heavy metals such as lead and mercury, while softening water and inhibiting scale. It is designed for household reverse osmosis systems (as a pre-filter CTO or post-filter T33), direct drinking water dispensers, built-in refrigerator water filters, and commercial coffee machines. Zanxis manufactures this filter in Zhongshan, Guangdong, China, and supports custom sizes from Ф30 to Ф60 mm.

Before you finalize a specification, confirm the values that directly affect fit and performance. The standard size list gives outer diameter and length, but your housing may require a specific inner diameter or end-cap configuration. Ask for a drawing check if you are unsure. The filtration precision is described as high with uniform micropores, but the exact micron rating should be confirmed for your application. Flow rate and pressure drop depend on the carbon block structure and water conditions; request the flow-pressure curve for your intended use. The service life is influenced by water quality and daily volume; plan replacement based on your local water test results. The ion exchange resin contributes to softening and heavy metal reduction, but capacity varies with influent hardness. For commercial coffee machines, confirm that the rod diameter and length fit the machine’s filter head. Zanxis can provide test reports from its CNAS-accredited laboratory covering efficiency, dust holding, and resistance, so you can verify these values against your requirements.
Follow this sequence to validate the filter for your product:
The filter is made from high-iodine coconut shell activated carbon and food-grade ion exchange resin, sintered into a rigid rod. The sintering process creates a uniform microporous structure that provides high initial flow and high filtration precision while preventing the release of black carbon fines. The ion exchange resin is embedded to soften water and reduce heavy metals such as lead and mercury. The rod is intended as a replacement element in water purifiers, refrigerators, and coffee machines. It is not a stand-alone purifier; it must be installed in a compatible housing. The standard sizes cover a range of outer diameters from Ф32 mm to Ф62 mm and lengths from 57 mm to 240 mm, with the Ф60×240 size being a common configuration. For other dimensions, Zanxis offers custom molding, including end-cap welding, to match your equipment. Typical replacement intervals are 6–12 months depending on water quality and usage; monitor for reduced flow or taste changes.
Zanxis supports filter verification with its own CNAS-accredited laboratory, which can issue test reports for filtration efficiency, dust holding capacity, and resistance. The production base in Zhongshan, Guangdong, China, covers 50,000 m², including 6 clean workshops totaling 20,000 m². The company has been certified to IATF 16949 (achieved in 2024) and holds ISO 9001, ISO 14001, and ISO 45001 certifications. Products comply with REACH and RoHS environmental regulations, and compliance documents are available. Quality control follows IQC, IPQC, and OQC processes across the production flow. With more than 20 years of experience in filtration R&D and manufacturing, Zanxis has supplied customers in Europe, the United States, Japan, and South Korea for over two decades. The company offers OEM/ODM services for dimensions, structure, filter media grade, end cap material, logo, and packaging, and has developed over 1,000 filtration solutions. Multiple automated production lines support a monthly capacity of millions of pieces.
To request samples and test reports, please provide the following details: your device or vehicle model, required size or drawing, target flow rate or water flow, operating conditions (pressure, temperature, water quality), and estimated quantity. This information helps Zanxis recommend the right specification and prepare an accurate quotation. Contact us via our contact page.
Yes. Zanxis can supply test reports from its CNAS-accredited laboratory covering filtration efficiency, dust holding capacity, and resistance. These reports are generated for the specific product and can be provided with samples or quotations. Please specify the parameters you need verified when requesting.
Standard samples are typically available quickly, while custom samples require 7–15 days for development. After you receive the sample, the validation period depends on your own testing protocol. Zanxis recommends allowing enough time to assess fit, flow, and filtrate quality under your operating conditions.
MOQ for the standard Ф60×240 size is generally 1,000–2,000 pieces. For customized specifications, MOQ can be negotiated based on complexity. Please confirm the exact MOQ with the sales team when requesting a quotation.
Lead time depends on whether the item is in stock or customized. Standard stock items typically ship within 7–15 days, while OEM orders generally require 25–35 days including mold confirmation and sampling. Zanxis will confirm the schedule upon order placement.
Under normal conditions, the recommended replacement interval is 6–12 months, depending on water quality and daily usage. Reduced flow or noticeable taste and odor changes may indicate it is time to replace. Always follow your appliance manufacturer’s guidelines.
Yes. Zanxis offers full OEM/ODM customization, including outer and inner diameters, length, and end-cap welding. Molds can be made to match your equipment. Provide a drawing or sample, and the engineering team will evaluate feasibility and lead time.
Yes. Samples are available for evaluation. Standard samples can be shipped quickly, while custom samples take 7–15 days. Samples can be accompanied by relevant test reports. Contact Zanxis with your specifications to request a sample.
