The Thesvin sintered activated carbon filter rod Ф60×240 is a coconut-shell carbon block with built-in ion-exchange resin, designed for water purifiers, refrigerators, and coffee machines. It reduces chlorine, taste, odour, and heavy metals such as lead and mercury. It suits OEM/ODM manufacturers and brands needing a drop-in or custom-fit carbon cartridge. Thesvin manufactures it in Zhongshan, Guangdong, China.
This carbon rod installs as a cartridge inside the filter housing of a water purifier, refrigerator, or coffee machine. The 60 mm outer diameter and 240 mm length are reference dimensions for the standard Ф60×240 size; Thesvin also produces other diameters and lengths to match your housing. The rod’s cylindrical form seats into the housing cavity, and its end faces can be fitted with end caps that Thesvin can weld to your specification. Because the rod is rigid and self-supporting, it holds its shape under flow and does not require a separate support core. For custom fitment, Thesvin can adjust the outer diameter, inner bore ratio, and length so the rod locates correctly in your device. This approach is useful when you need a replacement for an existing cartridge or a new design for a compact appliance.
The filter medium is high-iodine-value coconut-shell activated carbon combined with food-grade ion-exchange resin. The carbon’s microporous structure adsorbs residual chlorine (bleach), off-flavours, off-colours, and organic compounds such as VOCs. The ion-exchange resin softens the water and helps reduce scale formation, while also capturing heavy metals including lead and mercury. The sintered structure gives a uniform pore network that provides an initial high flow rate and a mechanical filtration precision of ≥5 µm, intercepting sediment and rust particles. The rod is formulated to resist carbon fines, so it does not release black powder into the filtered water. Typical service life is 6–12 months depending on water quality and flow.

Thesvin operates a 50,000 m² production base in Zhongshan, Guangdong, China, including 6 clean workshops totalling 20,000 m². The company holds IATF 16949 (obtained in 2024) and ISO 9001, ISO 14001, and ISO 45001 certifications. Dimensional consistency is controlled through IQC, IPQC, and OQC at each stage, from incoming carbon and resin to finished rods. A CNAS-accredited laboratory issues test reports for filtration efficiency, dust holding capacity, and resistance, which can support your technical evaluation. Products comply with REACH and RoHS, and compliance documents are available on request. With over 20 years of filtration experience and more than 1,000 developed filter solutions, Thesvin supports OEM/ODM orders for dimensions, structure, media grade, logo, and packaging. Multiple automated lines provide monthly capacity in the millions of pieces. Standard sizes typically ship in 7–15 days; custom orders usually take 25–35 days after drawing approval and sampling.
To get an accurate quote, please provide: your device or vehicle model; a drawing or the old part for reference; the required flow rate or water flow; operating conditions such as pressure and temperature; and your estimated order quantity. Send these details through our contact page and our engineering team will respond with a fitment proposal and price.
The Ф60×240 size is a reference dimension; fitment depends on your housing’s inner diameter, length, and end-cap design. Thesvin can adjust the outer diameter, length, and end-cap welding to match your device. Send your housing dimensions or old cartridge for a fit check.
Yes. An old cartridge is often the quickest way to confirm interface dimensions, end-cap type, and flow path. Thesvin’s engineering team will measure it and propose a matching specification or a drawing for approval.
The carbon block removes ≥95% of residual chlorine and has a mechanical filtration precision of ≥5 µm, capturing sediment and rust. Under standard flow, service life is 6–12 months depending on water quality. The CNAS-accredited lab can provide test reports for your evaluation.
Yes. Thesvin supports OEM/ODM customisation of diameter, length, inner bore ratio, carbon type, resin loading, end caps, and packaging. Custom tooling is available to match your device requirements.
The MOQ for standard Ф60×240 rods is typically 1,000–2,000 pieces; custom sizes are quoted based on complexity. Standard stock ships in 7–15 days, while custom orders usually take 25–35 days after drawing approval and sampling.
Yes. Standard samples are usually dispatched within 3–5 working days, and custom samples take 7–15 days. Samples can include a CNAS lab test report covering flow, pressure drop, and chlorine removal.
Replace the rod every 6–12 months, or sooner if you notice reduced flow, taste, or odour. Actual interval depends on incoming water quality and daily volume. Thesvin can recommend a schedule based on your test results.
