Jiangsu Angkua Environmental Protection Technology Co., Ltd. manufactures gravity pitcher cartridges, sport bottle filters and coffee machine water filters at our production base in Nantong, Jiangsu. The Pitcher Water Filters & Coffee manufacturer range covers twelve production models that seat into cartridge holders already used by jug pitchers, travel bottles and bean-to-cup machines, supplied either as replacement-fit consumables or as branded OEM/ODM cartridges.
Gravity Pitcher, Bottle and Coffee Cartridges We Manufacture
Three drinking habits shape this range: pouring through a jug, filling a bottle or fountain, and brewing through an espresso or fully automatic machine. All twelve models run through the same moulding, media-filling and assembly lines, so a retail programme can combine pitcher, bottle and coffee items under one quality plan and one delivery schedule.
- Gravity pitcher cartridges — RF-85 Brita Classic, RF-102 Brita Premium, RF-67 Brita Universal, RF-110 Brita Longlast, RF-108 ZeroWater Ultimate and RF-47 Mavea/Brita Maxtra fit. These sit in the upper reservoir and rely on gravity head to drive water through the media bed.
- Bottle and multi-purpose cartridges — RF-75 CRF-950Z and RF-76 Brita Hard & Soft Sport fit narrow bottle necks and press-fit holders, where the cartridge is immersed or friction-retained.
- Coffee machine cartridges — RF-111 Delonghi ECAM/ESAM/ETAM/BCO.EC, Bosch Brita Intenza, RF-109 Philips CA6903 and RF-66 Krups F088 fit the water tank or inline holder and are resin-led to control hardness.
Matching the Cartridge to the Host Appliance
Fit is decided by the seat and the seal rather than by the media. Before a quotation is issued we confirm the interface points below against a sample, a drawing or the host appliance itself.

Media Stack and Food-Contact Materials
Our pitcher and coffee cartridges are built as layered media beds instead of single-stage strainers, so chlorine, taste, odour and dissolved metals are handled by the stage best suited to each.
- Pre-filtration — fine mesh or microporous paper layer that holds back suspended particles before the media bed loads.
- Carbon stage — coconut shell granular activated carbon for chlorine, taste and odour reduction.
- Ion-exchange stage — resin beads binding heavy metal ions such as lead and copper; in coffee cartridges this is the working element against scale-forming hardness.
- Optional mineral stage — mineral balls for pH balance where a market expects a mineral note in the finished water.
- Housing and seals — food-contact BPA-free AS, ABS and SAN grades paired with elastomer seals suited to the working temperature.
Media grade, bed depth and compaction are selected against the incoming water and the target cartridge life, which is why we ask for a water analysis rather than a catalogue number alone.
Specifications That Decide Fit and Cartridge Life
- Seat geometry — outer diameter, seat depth, seal face angle and any locating key or tab on the cartridge flange.
- Retention method — press-fit lip, quarter-turn bayonet or thread pitch, with the matching O-ring groove dimension.
- Flow against contact time — mesh aperture and bed compaction set the drip rate; gravity pitchers slow naturally as the bed loads, so initial flow is balanced against working capacity.
- Rated capacity — declared per model: the RF-85 Brita Classic Pitcher Filter is rated to treat up to 40 litres per cartridge.
- Temperature and pressure limits for the housing, cap and seal under normal use.
- Bypass prevention — the seal must stop unfiltered water from running around the media bed, which is verified during assembly and leak checks.
Coffee Machine Cartridges: Scale Control and Machine Protection
Coffee cartridges work to a different brief. The water is heated, the thermoblock or brew circuit is the asset being protected, and the cartridge sits in a tank or inline head rather than under gravity. We match body shape, thread or bayonet, riser length and O-ring to the tank geometry, then set the resin-to-carbon ratio for the hardness band of the destination market.
- Machine families covered in production: RF-111 Delonghi ECAM/ESAM/ETAM/BCO.EC series coffee machine water filter, Bosch Brita Intenza, Philips CA6903 and Krups F088 (RF-66).
- Immersion cartridges are dimensioned so they clear the tank floor and riser tube without floating or blocking the intake.
- Housing markings and reminder cycles can be adapted to a brand's recommended replacement interval.
OEM/ODM Configuration and Private Label Packaging
Most distributor and appliance-brand projects start from an existing body and then move one or more variables: media, branding, packaging or lock geometry. Our technical team works from your sample, drawing or host appliance and returns a configured specification for approval before tooling or a production run.
- Cartridge body and keying — proprietary lock profiles and dedicated seat geometry for aftermarket programmes that must not accept generic replacements.
- Branding — moulded or printed identification on the cartridge body, plus housing colour matching where the host product is part of the scope.
- Retail packaging — printed cartons, shelf-ready formats and multi-language user instructions.
- Replacement reminders — dials or colour-indicator rings where the host pitcher supports them.
Production, Inspection and Compliance
Our Nantong factory operates a quality management system certified to ISO9001 and an environmental management system certified to ISO14001. Water purification equipment is certified to international standards including NSF/FDA, DIN8077 and DIN8078, and complies with ISO15874 and GB/T18742. Every unit leaving our factory is checked against the agreed specification.
- Incoming verification of food-contact plastics, carbon media and resin before release to the line.
- Dimensional checks on moulded housings, caps and sealing faces for consistent seat fit.
- Leak and pressure checks on assembled cartridges to confirm seal integrity.
- Batch laboratory checks on finished filters, with documentation issued against the approved specification.
- Retention samples held for repeat orders so colour, flow and media behaviour stay consistent between runs.
Information We Use to Configure Your Solution
- Host brand and model, or a physical sample of the cartridge being replaced.
- Seat drawing or thread/lock dimensions where available.
- Incoming water data: total hardness, chlorine, TDS, iron and manganese levels.
- Target cartridge capacity in litres and the replacement interval expected by the market.
- Preferred flow behaviour and jug or tank volume.
- Branding, label language, packaging format and pack quantity.
- Annual volume, shipment destination and any compliance documentation the market requires.
Packaging, Delivery Scope and Serviceability
Cartridges are packed in reinforced cartons with moisture protection for ocean freight and palletised for container loading, so the moulded bodies and sealing faces arrive undistorted. Each shipment carries the agreed documentation, and user instructions can be printed in the languages of the destination market. Where the pitcher and cartridge programme sits alongside our other ranges, we coordinate packing and shipping with the Refrigerator Water Filters and dispenser lines so a mixed order ships as one consignment.
Frequently Asked Questions
Which pitcher cartridges can you supply as direct replacements?
Our production range covers RF-47 Mavea/Brita Maxtra, RF-75 CRF-950Z, RF-85 Brita Classic, RF-102 Brita Premium, RF-76 Brita Hard & Soft Sport, RF-67 Brita Universal, RF-108 ZeroWater Ultimate and RF-110 Brita Longlast, plus the Delonghi, Bosch, Philips and Krups coffee cartridges.
How do you set the rated capacity of a pitcher cartridge?
Capacity follows the media mass and the incoming water. We combine your water analysis with the target litres and replacement interval, then select carbon grade, resin volume and bed compaction to reach that working life.
Can you build a coffee machine filter for our own appliance brand?
Yes. Send the tank or holder drawing, or a sample cartridge, and we configure body shape, thread or bayonet, riser length and resin-to-carbon ratio, then confirm the geometry with a fit sample before full production.
What media goes into your pitcher cartridges?
A fine pre-filter layer, coconut shell granular activated carbon for chlorine and taste, ion-exchange resin for dissolved metals, and optional mineral balls for pH balance. Housings use food-contact BPA-free AS, ABS and SAN grades.
Do you supply the jug as well as the cartridge?
Our catalogue in this category is the filter cartridge itself; the jug, bottle or coffee machine is the host the cartridge seats into. OEM/ODM work centres on cartridge geometry, media, branding and retail packaging.
What do you need to quote a private-label programme?
The host model or sample, seat dimensions, water data, target capacity, branding and packaging requirements, annual volume and shipment destination. With those points we return a configured specification, sample plan and volume pricing for the programme.
