The Thesvin sintered activated carbon stick Ф60×130 is a coconut-shell carbon block water filter with ion exchange resin, designed as a drop-in cartridge for household reverse osmosis systems, water dispensers, side-by-side refrigerators and commercial coffee machines. It filters chlorine, taste and odour, colour, volatile organic compounds (VOCs), lead and mercury, and reduces scale build-up. It suits OEM/ODM buyers and equipment manufacturers who need a dimensionally matched cartridge for their host device or duct.
Fitment starts with the outside diameter and length. The Ф60×130 size is one of eight common reference dimensions Thesvin lists for this carbon stick range, alongside Ф62×240, Ф37.5×75, Ф38×57, Ф40×195, Ф51×127, Ф32×126 and Ф32×106. The nominal 60 mm diameter and 130 mm length are the primary locating features: the cartridge sits in the housing bore and the end faces seat against the housing or manifold. Because the block is a rigid sintered part rather than a loose-fill cartridge, the outside diameter and length need to match the cavity so the cartridge is located without bypass.
Thesvin supports full OEM/ODM customisation of outside diameter, length and the ratio of inner to outer diameter. That means a device that was designed around a different stick dimension can still be served by opening a tool to the required size. End-cap welding is also offered as a custom option, so the interface at the end of the cartridge can be adapted to the host manifold rather than forcing the device to accept a standard end form. The specifier should supply the housing bore, the available length, the centre-hole requirement and the end-cap geometry; Thesvin will confirm the tooling and sample route.
Because the block is sintered, it holds its shape under normal cartridge handling and does not release loose carbon fines into the downstream line. This matters where the cartridge is fitted upstream of a membrane or a dispense valve: the block is described as not shedding black powder, which keeps the seat and the downstream components clean. The fitment review should also confirm the flow direction and the available insertion clearance, since the rigid body needs a straight insertion path into the housing.
The filter medium is high-iodine-value coconut-shell activated carbon combined with food-grade ion exchange resin. The carbon adsorbs residual chlorine from municipal water, which is the source of the familiar bleaching-powder taste, together with off-tastes, odours and colour, and a range of volatile organic compounds. The ion exchange resin softens the water and helps reduce scale formation in kettles, boilers and dispense lines, and the combination is specified to intercept harmful heavy metals such as lead and mercury. Typical filtration accuracy is 5 micrometres, so the cartridge also captures fine particulate carried through the supply.
The uniform microporous structure gives a high initial flow, which is useful where the cartridge is fitted as a pre-filter (CTO position) ahead of an RO membrane, or as a post-filter (T33 position) at the dispense point. The high adsorption capacity supports a long service life, and the rigid sintered body means the cartridge keeps its dimensional stability through the service interval. The same construction is used in household RO systems, direct-drinking water dispensers, side-by-side refrigerator water filters and commercial coffee machines, where consistent water taste matters from the first cup to the last of the day.
Because the medium is a formed block rather than granular fill, the flow path through the wall is uniform, which helps keep the pressure drop predictable as the cartridge loads. The specifier should confirm the required flow rate and the inlet water quality so the 5-micrometre rating and the carbon/resin balance can be matched to the application. Thesvin can advise on cartridge selection based on the feed-water characteristics and the duty point of the host device.

Thesvin’s production base is certified to IATF 16949 (obtained in 2024) and to ISO 9001, ISO 14001 and ISO 45001. Dimensional consistency is controlled through IQC, IPQC and OQC checks across the production flow, so the outside diameter, length and centre hole of each batch are verified against the agreed drawing. The company operates a CNAS-accredited laboratory that can issue test reports covering filtration efficiency, dust-holding capacity and resistance, and the filter materials are produced to drinking-water safety and hygiene standards.
The facility covers 50,000 m², including six clean workshops totalling 20,000 m², and multiple automated production lines support a monthly capacity of millions of pieces. Products comply with REACH and RoHS environmental requirements, and compliance documents can be supplied. With more than 20 years of filtration product development and manufacturing experience, and continuous exports to Europe, the United States, Japan and South Korea, Thesvin supports OEM/ODM programmes covering size, structure, filter grade, end-cap form, logo and packaging, with more than 1,000 filtration solutions developed to date. The company is located in Zhongshan, Guangdong, China.
To get a fitment answer and a quotation, send the device or vehicle model, the required size or a drawing (an old cartridge is also acceptable as a reference), the airflow or water flow, the operating conditions and the quantity. Thesvin will confirm whether the Ф60×130 standard size fits or whether a custom diameter, length or end-cap weld is needed, then return sample and order details. Contact Thesvin with your requirements.
Fitment depends on the housing bore, the available length and the end-cap form. The Ф60×130 is one of eight reference sizes in this range, and Thesvin also supports custom outside diameter, length and inner/outer diameter ratio through OEM/ODM tooling. Send the housing dimensions or an old cartridge and Thesvin will confirm the match.
Yes. An old cartridge is a practical reference for outside diameter, length, centre hole and end-cap form. Thesvin will measure it and confirm whether the standard Ф60×130 size fits or whether a custom tool is required. A drawing is also acceptable if no old part is available.
The sintered block uses high-iodine-value coconut-shell activated carbon with food-grade ion exchange resin, with typical filtration accuracy of 5 micrometres. It adsorbs residual chlorine and off-tastes and odours, reduces colour, softens the water to help prevent scaling, and intercepts heavy metals such as lead and mercury. The rigid body does not shed black powder.
Yes. Thesvin supports full OEM/ODM customisation of outside diameter, length and inner/outer diameter ratio, and offers end-cap welding customisation. Logo and packaging can also be customised. Send the fitment dimensions and duty point so the tooling and sample route can be confirmed.
Samples are available for evaluation, and Thesvin will quote against the confirmed specification. Provide the device model, size or drawing, water flow, operating conditions and quantity so the sample and quotation can be prepared accurately. Use the contact page to start the request.
MOQ and lead time are confirmed against the final specification, including size, end-cap form and packaging. Because Thesvin manufactures in Zhongshan, Guangdong, China, with multiple automated lines, production scheduling can be aligned to the order. State the quantity and required delivery date in your inquiry for a firm answer.
Service life depends on inlet water quality and flow, and the high adsorption capacity supports a long interval. Replace the cartridge when flow drops noticeably, taste or odour returns, or the device indicator calls for a change. Thesvin can advise on the interval once the feed-water chlorine level and duty point are known.
Thesvin can provide compliance documents for REACH and RoHS, and the production base is certified to ISO 9001, IATF 16949, ISO 14001 and ISO 45001. The CNAS-accredited laboratory can issue test reports covering filtration efficiency, dust-holding capacity and resistance. State the target market so the correct document set can be prepared.
