This Oltaven coffee machine filter cartridge is a drop-in water purification filter compatible with Calphalon coffee machines. It reduces chlorine, odours, heavy metals and scale using a coconut-shell activated carbon and food-grade ion-exchange resin core. It is designed for home and commercial coffee machines, and for OEM/ODM custom projects.
The finished filter begins with the media: a blend of high-quality coconut-shell activated carbon and food-grade ion-exchange resin. The carbon targets chlorine and organic odours, while the resin helps manage scale-forming minerals and certain heavy metals. These materials are selected for their ability to improve water taste and protect the coffee machine.
But media alone does not make a filter. Forming turns loose material into a cartridge that fits and performs. The media is contained within a structure that guides water through it at a controlled rate. The forming approach—how the media is packed, how the cartridge is assembled and sealed—determines whether the finished filter delivers the intended contact time, flow and capacity. Oltaven sells finished filters, not just media, so each cartridge is built to meet the performance requirements of the application.
Three factors in the finished filter directly affect efficiency, resistance and capacity.
Media choice sets the baseline: the type and amount of carbon and resin determine what contaminants can be removed and how much water can be treated before replacement.
Pleating and packing—in filters that use pleated media—maximise surface area within a compact size, improving capacity and lowering resistance. In this cartridge, the media is packed to balance contact time with flow rate, so water is effectively treated without excessive pressure drop.
Framing and sealing ensure the filter fits the machine correctly, prevents bypass and maintains structural integrity under operating pressure. Proper sealing means water goes through the media, not around it, so the rated efficiency is achieved in real use.
Together, these choices explain why filters of the same size can differ in resistance, capacity and life. The finished design is a system, not just a material.
This filter is compatible with Calphalon coffee machines and is suitable for:
It is intended for cold water filtration only, with an operating temperature range of 2°C to 38°C and an operating pressure of 20–120 psi (approximately 1.4–8.3 bar).

Oltaven brings over 20 years of experience in filtration research and manufacturing to every cartridge. Our OEM/ODM capabilities have resulted in more than 1,000 developed filtration solutions, allowing us to adapt designs to specific machine requirements and market needs.
Production takes place in a 50,000 m² plant in Zhongshan, Guangdong, China, which includes six cleanrooms totalling 20,000 m². This controlled environment helps maintain product cleanliness and consistency.
Our in-house laboratory is CNAS-accredited and can issue test reports on filtration efficiency, dust holding capacity and resistance, supporting product validation.
We operate under ISO 9001, ISO 14001 and ISO 45001 management systems, and since 2024 have held IATF 16949 certification for automotive quality management. Products comply with REACH and RoHS regulations, and we can provide the relevant compliance documents.
Quality control follows IQC, IPQC and OQC processes throughout production, and multiple automated lines support a monthly capacity of millions of units.
We support custom projects from concept to delivery. The typical workflow:

Resistance depends on how the media is packed and formed inside the cartridge. Factors such as media type, amount, pleating (if used) and the internal flow path affect pressure drop. Two filters with identical external dimensions can have different internal designs, leading to different resistance and flow characteristics. Oltaven optimises these factors to balance resistance with filtration performance for each application.
An OEM project starts with your inquiry. Provide the device model, required size or drawing, target flow rate and operating conditions, and estimated quantity. Our team evaluates the requirements and proposes a design, then develops samples for your testing. After approval, we proceed to production with full quality control.

This filter uses coconut-shell activated carbon and ion-exchange resin to reduce chlorine, odours, heavy metals and scale. The exact efficiency depends on water quality and flow rate. For specific performance data, please request a test report from our CNAS-accredited laboratory.
Yes. We offer OEM/ODM customisation including dimensions, connection structure, media formulation (e.g., enhanced chlorine removal, softening, lead removal), housing colour and logo, packaging design, and multilingual manuals. With over 1,000 developed filtration solutions, we can adapt quickly to your machine model and market requirements.
For standard compatible models, the MOQ is 5,000 pieces, with a lead time of 15–20 days for stock or small batch orders. For OEM customised models, the recommended MOQ is 10,000 pieces, with a production lead time of about 25–30 days including tooling and packaging development. Our monthly capacity of millions of units supports large-scale orders.
The filter life is approximately 250 litres or 2–3 months, depending on local water quality and usage frequency. Replace the cartridge when you notice reduced flow, taste changes, or after the recommended period to ensure consistent water quality and machine protection.
Yes. Standard stock samples can be shipped within 3–5 working days. Custom samples typically take 7–15 days depending on complexity. Samples come with CNAS laboratory test reports, and you may also arrange third-party verification. We encourage testing before placing an order.
The production system is certified to ISO 9001, ISO 14001, ISO 45001, IATF 16949 and medical supplies GMP standard. The filter materials meet food-grade requirements and comply with REACH and RoHS regulations. Our CNAS-accredited lab provides test reports for filtration performance. These certifications support market access in Europe, the US, Japan and Korea.
