This Oltaven coffee machine filter cartridge is a triple-stage water purification filter compatible with MR.COFFEE machines. It reduces chlorine, odours, hardness minerals and heavy metals such as lead and mercury, while retaining the water's natural taste for a cleaner cup. It suits households and offices using automatic or drip coffee machines, water dispensers, ice makers and sport filter bottles.
A filter is only as good as the way its media are combined. This cartridge layers three materials in sequence: an outer high-density microfibre layer traps sediment and rust; a bed of high-iodine coconut shell activated carbon adsorbs chlorine, organic odours and off-flavours; and food-grade ion exchange resin softens the water by exchanging calcium and magnesium ions for sodium, which helps prevent scale build-up in the machine.
Oltaven sells finished filters, not just media. The efficiency, pressure drop and capacity of the final product depend on how those media are pleated, wound, filled and sealed into the housing. A loose carbon bed can channel; an over-compressed one can block flow. Our forming process balances media weight and density so that water contacts the full bed at a stable flow rate, and the housing is sealed to prevent bypass. That is why two filters of the same size can behave very differently.
Three factors decide how a finished cartridge performs. First, media selection: the iodine value of the coconut carbon determines how much chlorine and taste material it can hold, and the resin's exchange capacity sets how much hardness it can remove before exhaustion. Second, forming: pleating, winding or filling must be uniform so water does not take a shortcut through the bed. Third, sealing and housing: a precise fit between the filter and the machine's inlet prevents unfiltered water from bypassing the cartridge.
Because Oltaven controls all three, we can tune a cartridge for different water conditions. For hard water areas, we can adjust the resin-to-carbon ratio; for high-sediment supply, we can increase the outer fibre density. The result is a finished filter whose resistance and capacity match the machine and the local water, not just a specification on paper.
In each case the filter's job is the same: protect the appliance from scale, reduce chlorine and odours, and keep the beverage's flavour clean.
| Item | Detail |
|---|---|
| Product name | Coffee machine water filter cartridge / water dispenser filter |

| Core media | Food-grade ion exchange resin, high-iodine coconut shell activated carbon, high-density fibre |
| Key performance | Softens water and inhibits scale; adsorbs residual chlorine and odours; intercepts sediment and harmful heavy metal ions such as lead and mercury |
| Typical end uses | Automatic and semi-automatic espresso machines, drip coffee makers, high-end water dispensers, ice makers, sport filter bottles |
| Customisation | 100% OEM support: housing shape, connector clip style and internal media ratio can be tooled to the customer's machine requirements |
| Quality systems | 50,000 m² plant certified to ISO 9001 and IATF 16949; filter media meet potable water safety standards and are tested by a CNAS-accredited laboratory |
Oltaven brings more than 20 years of filtration experience and OEM/ODM capability to every cartridge. We have developed more than 1,000 filtration solutions and support custom sizes, structures, media grades, logo and packaging.
Our production base in Zhongshan, Guangdong, China, covers 50,000 m², including six cleanrooms totalling 20,000 m². The plant holds IATF 16949 (obtained in 2024) and ISO 9001, ISO 14001 and ISO 45001 system certifications. An in-house CNAS-accredited laboratory can issue test reports on filtration efficiency, dust holding capacity and resistance. Products comply with REACH and RoHS, and compliance documents are available on request.
To quote a finished filter for your machine, tell us the device or vehicle model, the size or a drawing, the required water flow, your operating conditions (water hardness, sediment level), and the quantity you plan to order. Contact Oltaven to start the conversation.
Resistance depends on how the media are formed inside the housing. A tightly packed carbon bed or a denser outer fibre layer increases resistance, while a loose bed lowers it but may allow channelling. Oltaven balances media weight, density and pleating so the finished cartridge delivers stable flow at the intended resistance for your machine.
It starts with your machine model, a sample or drawing, target flow rate and local water conditions. Oltaven then proposes a media ratio and housing design, produces samples for your testing, and after approval confirms MOQ, price and lead time. Customised development typically takes 15–30 days for sampling.
Yes. With over 20 years of development experience and more than 1,000 filtration solutions, Oltaven can develop compatible cartridges for other mainstream coffee machine brands based on your sample or drawing. The development cycle is usually 15–30 days.
The triple-stage construction reduces chlorine, odours, hardness minerals and heavy metals such as lead and mercury, and retains the coffee's natural flavour. The standard service life is 2 months or 60 gallons (about 227 litres) of water, and the media ratio can be adjusted for local water quality.
For stock models, Oltaven provides 1–3 free samples for evaluation; you only cover international courier cost. Custom samples are charged, and the sampling fee can be deducted from the bulk order. Send your device model, size or drawing, flow requirement and quantity through our contact page for a quote.
Standard models usually have an MOQ of 1,000–2,000 pieces. Custom projects are negotiated based on specification and packaging. Standard orders ship in 25–35 days, custom orders in 35–45 days, depending on quantity and specification.
Replace it every 2 months or after 60 gallons (about 227 litres) of water, whichever comes first. In areas with harder water or higher sediment, the interval may need to be shorter; Oltaven can adjust the media formulation for your local conditions.
Oltaven locks in long-term suppliers and checks a COA for every batch of carbon and resin, uses automated filling equipment to control media weight and density, and has the CNAS laboratory sample-test each finished batch for flow and efficiency. Retention samples are kept for 3 years for traceability. Contact us to discuss your project.
