This Zanxis coffee machine filter cartridge is a triple-stage water purification filter compatible with MR.COFFEE machines, combining a fibrous outer layer, coconut-shell activated carbon and ion-exchange resin. It reduces chlorine, odours, sediment, heavy metals and hardness scale that can impair coffee flavour and damage appliances. It is designed for automatic and semi-automatic espresso machines, drip coffee makers, high-end water dispensers, ice makers and sports filter bottles. Zanxis manufactures it in Zhongshan, Guangdong, China, with full OEM customisation.
| Item | Detail |
|---|---|
| Product name | Coffee machine water filter cartridge / water dispenser filter |
| Filtration principle and structure | Triple-stage precision filtration: 1) fibrous outer layer; 2) coconut-shell activated carbon; 3) ion-exchange resin |
| Core purification materials | Food-grade ion-exchange resin, high-quality coconut-shell activated carbon, high-density fibre |
| Core performance | Scale prevention and water softening; effective adsorption of residual chlorine and odours; interception of sediment and harmful heavy metal ions such as lead and mercury |
| Main applications | Automatic and semi-automatic espresso machines, American-style drip coffee makers, high-end water dispensers, ice makers, sports filter bottles |
| Dimensions and customisation | 100% OEM support. Housing shape, connector clip style and internal filter material ratio can all be tooled to match the customer’s appliance requirements. |
| Quality certification | 50,000 m² plant certified to ISO 9001 and IATF 16949. Filter materials meet stringent water-contact safety standards and are backed by a national-level CNAS testing centre. |
Before approving a filter for a coffee platform, confirm the values that directly affect fit and brewing performance. The triple-stage structure is fixed—fibre, carbon, resin—but the balance between stages and the housing interface can be adjusted. Key confirmations include the connector type and housing dimensions, the target flow rate at your machine’s pump pressure, and the expected inlet water quality (hardness, chlorine level, sediment load). These determine the resin-to-carbon ratio and the service life you can expect. Zanxis supplies sample cartridges and CNAS-accredited lab reports covering efficiency, dust holding and resistance so you can verify these values on your own bench.
This workflow lets you verify performance before committing to volume. Custom sample development typically takes 15–30 days.
The cartridge is built around three functional layers. The outer high-density microfibre layer intercepts sediment and rust particles, protecting the inner media. The middle layer uses high-iodine-value coconut-shell activated carbon to adsorb residual chlorine, organic odours and taste-impairing compounds, helping to restore the coffee’s original flavour. The inner layer contains food-grade ion-exchange resin that softens water by exchanging calcium and magnesium ions, reducing scale build-up in the boiler and brew path. This combination also targets harmful heavy metal ions such as lead and mercury. The cartridge is compatible with MR.COFFEE machines and can be specified for other appliance platforms through OEM tooling. Standard service life is 2 months or 60 gallons (about 227 litres), but this can be adjusted with resin and carbon ratios to suit local water conditions. Zanxis has developed over 1,000 filtration solutions and can tailor the media blend, housing shape and connector style to your appliance.
Zanxis operates a CNAS-accredited laboratory that issues test reports for filtration efficiency, dust holding capacity and resistance. These reports give you documented performance data to support your own validation. Production runs under ISO 9001, ISO 14001 and ISO 45001 systems, and the plant was certified to IATF 16949 in 2024. The 50,000 m² facility includes six clean rooms totalling 20,000 m², and quality control follows IQC, IPQC and OQC stages. Products comply with REACH and RoHS requirements, and compliance documents are available. With over 20 years of filtration manufacturing and export experience to Europe, the US, Japan and Korea, Zanxis supports OEM/ODM projects with automated lines capable of millions of pieces per month. The company is located in Zhongshan, Guangdong, China.
To receive samples, test reports and a quotation, tell us your device or vehicle model, the size or a drawing of the filter interface, the required airflow or water flow, your operating conditions (inlet water quality, pressure, temperature) and the quantity you plan to order. We will confirm the closest standard configuration or propose a custom build, and provide the relevant CNAS reports for your review. Contact our team with these details to start the verification process.
Yes. Zanxis issues test reports from its CNAS-accredited laboratory covering filtration efficiency, dust holding capacity and resistance. These reports are available for sample evaluation and bulk order documentation. They help you verify performance claims before approval.
For stocked models, samples are available immediately and you can test them on your machine within days of receipt. Custom samples typically require 15–30 days for development and production. After you receive the samples, allow time for fit, flow and taste testing on your own equipment.
Standard models have an MOQ of 1,000–2,000 pieces. Custom projects are quoted based on the specific dimensions, media configuration and packaging requirements. Contact us with your specifications for a firm MOQ.
Standard model orders usually ship in 25–35 days. Custom orders take 35–45 days, depending on quantity and specification. Lead times are confirmed at quotation. Zanxis has over 20 years of export experience to Europe, the US, Japan and Korea and can arrange FOB, CIF or DDP terms.
The standard replacement interval is every 2 months or after 60 gallons (about 227 litres) of water, whichever comes first. This can be adjusted by changing the resin and carbon ratios to suit local water hardness and chlorine levels. We can recommend a formulation for your market.
Yes. Zanxis offers full OEM/ODM customisation of housing shape, connector clip style and internal filter material ratio. Provide a sample or drawing of the target interface, and we will develop a matching cartridge. Custom development typically takes 15–30 days.
Raw materials are sourced from long-term suppliers with a certificate of analysis for each batch of carbon and resin. Automated filling equipment controls media weight and density. The CNAS laboratory performs sampling tests on flow and filtration efficiency for each production batch, and retention samples are kept for 3 years for traceability.
Provide your device model, filter size or drawing, required water flow, operating conditions (water quality, pressure, temperature) and planned order quantity. For stocked models, 1–3 free samples are available (you cover courier); custom samples are charged and the fee is credited against the bulk order. <a href="/en/contact">Contact us</a> to start.
