FILTER MEDIA / ROLLS · SHEETS · DIE-CUT
This Oltaven activated carbon filter cartridge is a drop-in water pitcher filter that combines high-iodine coconut shell carbon with ion exchange resin to reduce chlorine, taste and odour, soften water and capture heavy metals such as lead and copper. It is designed for household water pitchers, portable sports bottles and appliance water tanks. Oltaven supplies the finished cartridge, not loose media, so the pleating, forming and sealing that determine real-world efficiency and flow are engineered and controlled in our own plant.
A filter is only as good as the way its media is held, shaped and sealed. Loose carbon granules can adsorb contaminants, but without the right forming they channel, shed fines or block flow. In a finished pitcher cartridge, the carbon and resin are packed into a precisely moulded food-grade PP housing with an injection-moulded mesh that controls the path of water under gravity. The mesh retains carbon fines while letting water descend at a useful rate, so the cartridge delivers clear water without black specks.
Pleating and framing matter more in flat or cylindrical formats, where the pleat count sets surface area and the frame sets dimensional stability. In pitcher cartridges, the equivalent decisions are the media blend ratio, the compaction of the carbon bed and the sealing of the housing. Oltaven tunes these variables so the finished cartridge meets a target efficiency, resistance and capacity, rather than simply filling a shell with media.
Three factors drive the performance you measure at the tap: media choice, forming and sealing.
Because these three factors interact, two cartridges of the same external size can behave differently. A denser carbon bed may improve adsorption but raise resistance; a more open mesh may speed flow but shorten contact time. Oltaven balances these trade-offs against the intended use, water quality and target capacity.
Oltaven pitcher cartridges are used in household water pitchers, portable sports water bottles, desktop instant-heating dispensers and the water tanks of capsule coffee machines. In each case the cartridge reduces chlorine and odours that affect taste, softens water to limit scale and captures heavy metals such as lead and copper. For appliance customers, the cartridge can be shaped to fit an existing tank or developed as a new component. The same media and forming principles apply whether the final product is a retail pitcher or an integrated appliance filter.

| Quality and safety systems | Produced in the company’s 20,000 m² cleanroom area in line with international water-contact and food-contact safety standards; the company holds ISO 9001 and ISO 14001 certification and IATF 16949 certification |
Oltaven is an OEM/ODM filter manufacturer with more than 20 years of experience and more than 1,000 developed filtration solutions. Our 50,000 m² plant in Zhongshan, Guangdong, China, includes six cleanrooms totalling 20,000 m², where drinking-water cartridges are assembled and sealed. The in-house laboratory is CNAS-accredited and can issue test reports for filtration efficiency, dust holding capacity and resistance. The company holds IATF 16949 (obtained in 2024), ISO 9001, ISO 14001 and ISO 45001 certification, and products meet REACH and RoHS requirements with compliance documents available. IQC, IPQC and OQC checks run throughout production.
To quote accurately, please tell us the device or pitcher model, the size or a drawing, the required water flow, the operating conditions (water quality, pressure, temperature) and your estimated quantity. Send these details through our contact page and our team will respond with a proposal for a finished cartridge that meets your performance targets.
Resistance depends on how the media is formed and packed, not only on external dimensions. A denser carbon bed or a finer internal mesh increases contact time and adsorption but raises resistance, while a more open structure lowers resistance at the cost of shorter contact. Oltaven adjusts media blend, bed density and mesh design together to hit the flow and efficiency targets for each application.
An OEM project starts with your device or pitcher model, size or drawing, required flow rate, operating conditions and estimated quantity. Oltaven reviews these inputs, proposes a media ratio and housing design, and produces samples for your evaluation. Once the sample and commercial terms are approved, production follows with IQC, IPQC and OQC checks.
The cartridge combines high-iodine coconut shell carbon with ion exchange resin to reduce chlorine, taste and odour, soften water and capture heavy metals such as lead and copper. Performance is verified in our CNAS-accredited laboratory, and test reports can be issued for filtration efficiency, dust holding capacity and resistance. Because efficiency depends on media ratio and forming, we confirm the target performance with you before production.
Yes. Oltaven supports full OEM/ODM customisation of the housing shape and structure using customer-specific injection moulds, and the activated carbon to resin ratio can be adjusted for lead removal or scale reduction. Logo and packaging can also be customised. We confirm fit with your existing pitcher or water tank during sampling.
After you share the model, size or drawing, flow requirement, operating conditions and quantity, Oltaven prepares a quotation and sample plan. Samples are produced for your evaluation and can be tested at an agreed laboratory. Quotations reflect the chosen media blend, housing and packaging.
MOQ and lead time depend on the cartridge specification and packaging. Please include your estimated quantity in your inquiry so Oltaven can confirm the applicable MOQ and schedule. The 50,000 m² plant and multiple production lines support both standard and custom runs.
Replacement timing depends on the water quality, flow rate and daily volume in your application. Because capacity is set by the media blend and bed design, Oltaven agrees a target capacity with you during development. We recommend replacing the cartridge when the agreed capacity is reached or when flow slows noticeably.
The company holds ISO 9001, ISO 14001, ISO 45001 and IATF 16949 certification, and products meet REACH and RoHS requirements with compliance documents available. Drinking-water cartridges are assembled in cleanrooms totalling 20,000 m² within the 50,000 m² plant. Our CNAS-accredited laboratory can issue test reports. For a specific project, contact us to confirm the documents required for your market.
