The Zanxis activated carbon filter cartridge for water pitchers is a gravity-fed replacement cartridge that reduces lead, copper, and other heavy metals while adsorbing chlorine and organic odours. It combines a food-grade PP housing with high-iodine coconut-shell activated carbon and ion-exchange resin, and is designed for household water jugs, portable sports bottles, and small appliance water tanks. It is aimed at brands and distributors who need documented performance and a repeatable sample-sign-off process.
| Item | Detail |
|---|---|
| Product name | Water Pitcher Filter Cartridge (chlorine removal type) |
| Core filtration materials | Food-grade PP housing + high-efficiency coconut-shell granular activated carbon + quality ion-exchange resin |
| Core purification functions | Strong adsorption of residual chlorine, off-colours and odours; water softening (reduction of calcium and magnesium scale); interception of harmful heavy metals such as lead and copper; filtration of sediment, rust and suspended solids |
| Flow and filtration characteristics | Precision injection-moulded filter mesh designed for good gravity-flow downflow rate while preventing internal carbon fines from leaking; no black water during use |
| Main application end-products | Household water pitchers, portable sports water bottles, desktop instant-hot water dispensers, built-in water-tank filter cartridges for capsule coffee machines |
| Media ratio and mould customisation | 100% OEM flexible contract manufacturing supported. The mixing ratio of activated carbon to resin can be adjusted for target lead-removal and scale-reduction needs; housing structure and shape fully support customer-specific injection moulds |
| Quality certification and safety systems | Produced in the company's 20,000 m² clean workshops, conforming to international water-contact and food-contact safety standards. The company holds ISO 9001, ISO 14001 and IATF 16949 certification |
Before a sample is built, we recommend fixing the values that will be written into the specification. The table above gives the baseline; the following points are the ones that most often change between projects and should be agreed in writing.
Any figure not confirmed at this stage is treated as open, not as a default.
The cartridge is built around a food-grade PP housing that is injection-moulded to the shape of your pitcher or bottle. Inside, high-iodine coconut-shell activated carbon provides fast adsorption of residual chlorine and odours, while ion-exchange resin softens the water and helps intercept heavy metals such as lead and copper. A precision-moulded mesh retains the media and allows gravity downflow without releasing carbon fines, so the water stays clear.
Because the housing is produced on customer-specific moulds, the outer shape, colour and logo can follow your product line. The carbon-to-resin ratio is adjusted at the filling stage, which means one housing platform can serve several performance tiers. Typical installations include household water pitchers, portable sports bottles, desktop instant-hot dispensers and the built-in water tanks of capsule coffee machines; the cartridge is a replaceable component in these systems.
For use, the cartridge is fitted into the appliance or vessel according to the agreed interface, and water is passed through under gravity. Replacement intervals depend on the inlet water quality and daily volume; agree the interval during sample sign-off so that the retail pack can state it accurately.
Verification starts with the laboratory. Zanxis operates a self-built laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment), which can issue test reports covering filtration efficiency, dust holding and resistance. These reports are the reference documents for sample sign-off and for your own market submissions.
Production sits in a 50,000 m² plant in Zhongshan, Guangdong, China, including six clean workshops totalling 20,000 m². Quality control follows IQC, IPQC and OQC across the process, and the company has held ISO 9001, ISO 14001 and ISO 45001 certification; IATF 16949 was added in 2024. Products can be supplied with REACH and RoHS compliance documents on request. With more than 20 years of filtration development and manufacturing, and exports to Europe, the United States, Japan and South Korea over that period, Zanxis has developed over 1,000 filtration solutions and supports OEM/ODM customisation of size, structure, media grade, housing material, logo and packaging.

With these inputs, Zanxis can propose a media ratio, confirm the sample timeline and issue the matching test report for your review.
Yes. Zanxis operates a CNAS-accredited laboratory that can issue reports covering filtration efficiency, dust holding and resistance for the agreed specification. The report is tied to the sample you sign off, so the values match the production configuration.
The timeline depends on whether a new housing mould is required and which parameters you want measured. After the test brief is agreed, Zanxis builds the sample and runs the in-house verification, then sends the report for your review. The exact schedule is confirmed with the quotation.
Lead removal is verified in the CNAS-accredited laboratory against the inlet challenge water and target reduction you specify in the test brief. The carbon-to-resin ratio is adjusted before sampling so that the measured result reflects the intended media blend.
Yes. The housing is produced on customer-specific injection moulds, so the outer shape, colour and logo can follow your product. The carbon-to-resin ratio can also be adjusted for different lead-removal or scale-reduction targets.
MOQ and lead time are set per project because they depend on the housing mould, media ratio and packaging. Zanxis confirms both in the quotation after reviewing your device model, drawing and estimated annual quantity.
The replacement interval depends on the inlet water quality and the daily volume passed through the cartridge. Agree the interval during sample sign-off so the retail packaging can state it accurately for your market.
Zanxis can provide REACH and RoHS compliance documents on request, and the production system holds ISO 9001, ISO 14001, ISO 45001 and IATF 16949 certification. State the declarations your market requires when you request the sample.
