This Oltaven coffee machine filter cartridge is a water purification filter compatible with CAPRESSO coffee machines. It combines high-quality coconut shell activated carbon and food-grade ion exchange resin to reduce chlorine, odours, heavy metals and scale from cold water, protecting the machine's heating system and supporting clearer coffee flavour. It is designed for automatic, semi-automatic and commercial coffee machines, and for businesses seeking OEM water filter manufacturing.
A filter's performance is not set by the media alone. The choice of media determines what can be adsorbed or exchanged, but the finished filter's efficiency, pressure drop and capacity are decided by how that media is pleated, framed and sealed. Oltaven sells finished filters, not just media, so we control every step from material selection to final assembly.
In this cartridge, coconut shell activated carbon provides a large surface area for adsorbing chlorine and organic substances, while ion exchange resin reduces hardness minerals that cause scale. The media is held within a structure that directs water flow evenly, and the housing and seals prevent bypass. This combination is what delivers consistent filtration in the finished product.
Three factors determine how a filter performs in service: efficiency, resistance and capacity. Efficiency depends on the media's contact time with water and the pore structure; resistance (pressure drop) is influenced by the density of the media bed and flow path design; capacity is governed by the amount of active media and the operating conditions. In this cartridge, the activated carbon and ion exchange resin are selected and processed to balance these factors, so the filter delivers reliable reduction of chlorine, odours, heavy metals and scale over its service life.
Forming also matters. The pleating or packing of media, the framing that holds it, and the sealing that prevents water from bypassing all affect the final result. Oltaven's manufacturing experience ensures that each cartridge is assembled to consistent tolerances, so the performance you test is the performance you receive.
This filter is suitable for automatic coffee machines, semi-automatic espresso machines, and commercial coffee machine water softening. It is also used in OEM water filter cartridge customisation projects. The cartridge operates with cold water only, at temperatures from 2°C to 38°C and pressures from 20 to 120 psi (approximately 1.4 to 8.3 bar), making it compatible with typical coffee machine water systems.

Oltaven brings over 20 years of filtration product development and manufacturing experience to every project. We support OEM/ODM services with customisation of size, structure, filter media grade, frame material, logo and packaging, and we have developed more than 1,000 filtration solutions. Our production base covers 50,000 square metres, including six cleanrooms totalling 20,000 square metres, where cartridges are assembled in a controlled environment to avoid secondary contamination. Our in-house laboratory is CNAS-accredited and can issue test reports for filtration efficiency, dust holding capacity and resistance. We are certified to ISO 9001, ISO 14001, ISO 45001 and IATF 16949 (obtained in 2024), and our products comply with REACH and RoHS regulations, with compliance documents available upon request. Our quality control covers IQC, IPQC and OQC throughout the production process. Located in Zhongshan, Guangdong, China, we have been exporting to Europe, the United States, Japan and South Korea for over 20 years.
To discuss a custom filter project, please provide the following details: your device or vehicle model, the required size or a drawing, the airflow or water flow, the operating conditions (temperature, pressure, water quality), and your estimated quantity. This information helps us recommend the right configuration and provide an accurate quote. Contact us to start the conversation.
Resistance, or pressure drop, depends on the internal design: the density of the media bed, the flow path, and the way the media is pleated or packed. Even if two filters have the same outer dimensions, differences in media selection and forming can lead to different resistance. This Oltaven cartridge is engineered to balance resistance with efficient filtration for coffee machine applications.
An OEM project starts with your requirements: device model, desired size or drawing, water flow, operating conditions and estimated quantity. We then develop samples for your evaluation, typically within 2–3 weeks. After sample approval, we provide a quotation and schedule production.
Yes, we offer OEM/ODM customisation of filter media grade, housing structure, size, connections, logo and packaging. Our team can adapt the cartridge to fit your specific machine model while maintaining filtration performance.
For standard compatible models, the MOQ is 5,000 pieces. For custom OEM models, we recommend an MOQ of 10,000 pieces or more to optimise production efficiency. Please contact us to discuss your specific needs.
Sample development usually takes 2–3 weeks. For standard models, delivery is typically within 15–20 days. Custom OEM orders generally require 25–30 days after sample approval and packaging development.
The filter life is approximately 250 litres or 2–3 months, depending on local water quality and usage frequency. We recommend replacing the cartridge when you notice a decrease in flow or changes in water taste, or according to your maintenance schedule.
Yes, we can provide samples for evaluation. Please share your device model and requirements, and we will arrange samples. Sample costs and shipping terms can be discussed based on your location and project scope.
