Wholesale Faucet Water Filter Manufacturers

Air Filter and Faucet Filter Elements Built for Appliance and Tap Fitment

Jiangsu Angkua Environmental Protection Technology Co., Ltd. manufactures appliance air filter elements and faucet water filter cartridges at our production base in Nantong, Jiangsu. Both families live or die on the same three requirements: the housing must seat on the host interface without play, the seal must hold at municipal line pressure, and the media must deliver its rated reduction across the whole service interval. We mold, assemble and test both families in house, so those tolerances hold from a pilot batch through to a full container load.

As an Air filter & Faucet filter manufacturer, we supply appliance brands, water treatment distributors, retail private-label programs and OEM/ODM buyers who need replacement consumables that fit correctly on the first attempt. The RF-series air elements and faucet cartridges covered here sit alongside our broader refrigerator water filters and water purification systems.

Our Range: Air Filter Elements, Kitchen Cartridges and Direct-Install Parts

Refrigerator and appliance air filter elements

These elements treat the circulating air inside a refrigerator cabinet or a portable purifier body rather than water. A flat molded frame keeps the media square to the airflow path, and the graded stack starts with a layer that catches lint and coarse dust before air reaches the bonded activated carbon that handles odour, and volatile organic compounds.

• RF-30 — dimensioned for LG LT120F ADQ73214404 and Kenmore 46-9918 air modules.
• RF-31 and RF-32 — built against the Electrolux PAULTRA EFACBF and AFCB series bodies.
• RF-43 — matched to W10311524 AIR1 refrigerator air units.
• RF-77 — a purifier cartridge for HAP242-NUC series housings, with pleated media plus carbon.

Faucet-mounted and direct-install water filter cartridges

Kitchen cartridges mount either on the tap itself or inside a faucet-mounted diverter body. Carbon block covers chlorine, taste and odour; where the target water carries dissolved metals or a heavier sediment load, we build composite stacks that add KDF copper-zinc media or an ultrafiltration layer ahead of the carbon. Our RF-73 (FM-15RA) and RF-74 / RF-9999 cartridges use a multi-layer carbon block, while RF-113 and RF-114 are direct-install cartridges for Brita faucet-mount bodies in premium and Select configurations.

Range at a Glance

Application Fit by Water Chemistry and Air Condition

• Chlorinated municipal supply with taste and odour complaints — activated carbon block cartridges across the faucet range.
• Older distribution networks carrying sediment — graded media with a sediment wrap so the carbon stage is not blinded early.
• Dissolved lead, mercury or elevated metal content — composite stacks that place KDF copper-zinc media ahead of the carbon block.
• Microplastic and colloidal loading — ultrafiltration composite where the project target is fine particulate, not chlorine alone.
• Refrigerator cabinets with odour cross-transfer between foods — activated carbon air elements with an even airflow path.
• Bedroom and pet-area purifiers — pleated media plus carbon for dust, pollen and persistent odour.

Materials and Critical Specifications

• Housings and covers: food-grade ABS, with electroplated or metal-look finishes on visible faucet bodies.
• Seals: anti-ageing silicone and food-grade elastomer gaskets selected for compression set.
• Media: activated carbon block, KDF copper-zinc blends, ultrafiltration membrane, and synthetic pleated media for air.
• Flow and pressure: cartridges are configured for roughly 1.5–2.0 GPM at typical municipal supply pressure, with hydrostatic testing above normal residential peaks.
• Capacity: carbon block configurations typically run 200–300 gallons, and KDF composite builds 300–500 gallons, against the reference water quality used at design.
• Air elements are dimensioned to the host appliance's stated replacement interval rather than to a fixed calendar life.

Configuration Options and OEM/ODM Scope

• Adapter kits — internal-thread adapter, external-thread adapter and a universal high-compression gasket clamp for unthreaded or unconventional spouts.
• Diverter design — a dual-flow valve that switches between filtered and unfiltered water without cross-contamination between chambers.
• Lifespan indication — mechanical month dial, transparent sediment window, or a flow-meter LED that shifts colour with volume used.
• Branding — laser etching, Pantone-matched housing colour, and customer carton artwork.
• Tooling — in-house mold design and CNC work for proprietary housing shapes, plus private-label assembly.

Quality Control, Testing and Compliance

• Incoming inspection of plastics, silicone seals and filtration media against agreed composition and purity.
• Hydrostatic pressure testing of assembled housings above standard residential operating parameters.
• 100% leak testing on finished cartridges before final assembly and boxing.
• Dimensional verification against the host interface drawing, a customer sample or a supplied OEM part.

Our water contact products are certified to international benchmarks including NSF/FDA, DIN 8077 and DIN 8078, and comply with ISO 15874 and GB/T 18742 as applicable. The Nantong plant in China operates under ISO 9001 and ISO 14001 management systems, and the compliance documents relevant to each shipment are issued with the order.

Installation, Acceptance and Maintenance

Faucet cartridges are designed for tool-free mounting on standard spouts through a gasket seal or threaded collar, and a replacement takes only a few minutes: shut off the tap, unthread the old cartridge, align the keyed collar and hand-tighten. Air elements follow the appliance routine — isolate power, open the panel or side cover, extract the old element without scattering dust, seat the new one in its guide slot and restore power.

Acceptance at our end covers dimensional fit, leak integrity and media data, and we retain batch records for the cartridges shipped. Replacement cartridges, adapter sets, gaskets and diverter levers are supplied as serviceable spares, and each order travels with an installation sheet, packing list and container loading record.

Information We Use to Configure Your Solution

FAQs on Air Filter Elements and Faucet Filter Cartridges

Can air filter elements and faucet cartridges be ordered together?

Yes. Both families are produced and tested at the same Nantong facility, so one order can combine refrigerator or purifier air elements with kitchen cartridges, adapters and spare gaskets under a single packing list and compliance set.

What do you need to match an element to a refrigerator or purifier model?

The OEM part number and host model are the starting point, for example a W10311524 AIR1 unit or a HAP242-NUC purifier body. Where the part number is unclear, a photo of the existing element with overall dimensions, or a physical sample, lets us confirm the frame, keying and gasket before tooling is committed.

Which filtration media can be specified for faucet cartridges?

Carbon block is the standard build for chlorine, taste and odour. KDF copper-zinc blends are added for dissolved metals and bacteriostatic control, sediment wraps protect the carbon in turbid supplies, and ultrafiltration composite is used where fine particulate is the primary target.

What flow rate and capacity should a faucet cartridge deliver?

Our faucet configurations target roughly 1.5–2.0 GPM at normal municipal pressure so routine kitchen use is not slowed. Carbon block builds are typically rated 200–300 gallons and KDF composites 300–500 gallons; the final figure is set against the water quality used when the media stack is selected.

How are the cartridges tested before shipment?

Incoming plastics, seals and media are inspected against agreed specifications, assembled housings are hydrostatically pressure tested above residential parameters, and every finished cartridge passes leak testing before packing. Dimensional checks are run against the host interface drawing or the approved sample.

Do you support private-label tooling and packaging?

We handle mold design and CNC work for proprietary housing shapes, offer laser etching, Pantone colour matching and custom carton artwork, and run pilot batches to validate a new colourway or retail format before full-container production.
