China Water Filter Cartridge Price Guide 2026

If you’re importing water filter cartridges and systems from China, the price range can swing 3–5× depending on specs, order volume, and shipping terms. This guide gives you real factory-direct price bands so you can budget before sending your first RFQ.

PP Sediment Filters (Melt-Blown / String-Wound)

Spec	FOB Ningbo (1000 pcs)	FOB Ningbo (10,000 pcs)
10” × 2.5” 5-micron PP	$0.25–0.40	$0.18–0.28
20” × 4.5” 5-micron PP	$0.55–0.85	$0.40–0.60
10” × 2.5” 1-micron PP	$0.35–0.55	$0.25–0.38

Tip: PP sediment is the highest-volume, lowest-margin cartridge. Focus on securing a stable supplier with consistent micron rating rather than squeezing the last cent.

Granular Activated Carbon (GAC) Cartridges

Spec	FOB Ningbo (1000 pcs)
10” × 2.5” Coconut shell GAC	$0.60–0.95
20” × 2.5” Coconut shell GAC	$1.10–1.60
10” × 4.5” High-flow GAC	$1.50–2.20

Critical spec: Iodine value. Cheap GAC uses 600 mg/g coal carbon. Premium uses 1000+ mg/g coconut shell. Price difference is ~30%, but performance difference is night and day.

Carbon Block (CTO) Cartridges

Spec	FOB Ningbo (1000 pcs)
10” × 2.5” Standard CTO	$0.70–1.10
10” × 2.5” High-performance CTO (NSF-grade)	$1.50–2.50
20” × 4.5” Extruded CTO	$2.50–4.00

CTO pricing depends heavily on the carbon raw material. NSF/ANSI 42–certified carbon block is 2–3× the price of generic block but sells for 5× at retail in regulated markets.

RO Membrane Elements

Spec	FOB Ningbo (100 pcs)
1812/2012 50 GPD (Household)	$3.50–5.50
1812/2012 75 GPD	$4.00–6.50
3012/3013 300–400 GPD	$7.00–12.00
4040 2000 GPD (Commercial)	$35.00–55.00
8040 8000 GPD (Industrial)	$180.00–280.00

RO membrane is the heart of any system. Dow/DuPont FilmTec commands a 30–50% premium over local Chinese brands (Vontron, Keensen, etc.). For markets that accept “made in China” membranes, the savings are substantial.

UF Hollow Fiber Membranes

Spec	FOB Ningbo (500 pcs)
10” × 2.5” PVC alloy UF	$2.50–3.80
10” × 2.5” PVDF UF (industrial)	$8.00–14.00
4040 PVDF UF module	$45.00–80.00

Complete Water Filter Systems

System Type	FOB Ningbo (MOQ 50)
3-stage under-sink (PP+GAC+CTO)	$8.00–15.00
5-stage RO under-sink (PP+GAC+CTO+RO+Post-carbon)	$22.00–38.00
Countertop RO dispenser	$45.00–75.00
Whole-house 3-stage (20” big blue)	$25.00–50.00

Shipping Costs: FOB → CIF

Adding sea freight from Ningbo to major ports (approximate Q2 2026 rates):

Destination	20GP Container	40HQ Container
Jebel Ali (UAE)	$900–1,200	$1,400–1,900
Lagos (Nigeria)	$2,000–3,200	$3,200–4,800
Novorossiysk (Russia)	$1,500–2,200	$2,400–3,500
Los Angeles (USA)	$1,000–1,500	$1,600–2,300
Mombasa (Kenya)	$1,800–2,800	$2,800–4,000

Carriers are volatile. Ask your forwarder for current rates before quoting CIF.

Landed Cost Formula

Landed cost per cartridge =
  (FOB unit price × quantity + sea freight + insurance + customs duty + clearance fees) ÷ quantity

Example: 10,000 pcs of 10” PP sediment at $0.25 FOB + $1,200 sea freight (40HQ) to Jebel Ali:

• FOB value: $2,500
• Sea freight: $1,200
• Insurance (~0.3%): $11
• Customs duty (5% UAE): $125
• Clearance + handling: ~$300
• Total landed: $4,136 for 10,000 pcs = $0.41/pc landed

What Moves the Price

1. Carbon quality — coconut shell vs coal-based, iodine value, mesh size
2. Membrane brand — Dow vs Vontron vs generic
3. Housing material — food-grade PP vs ABS vs stainless steel
4. Certification — NSF listing adds $0.30–1.00/pc in raw material and testing costs
5. Order volume — 10,000+ pcs usually unlocks the best tier pricing
6. OEM branding — laser engraving, color boxes, multilingual manuals add $0.10–0.50/pc

How to Get Accurate Quotes

Send your supplier:

• Cartridge type and dimensions (e.g., “10×2.5 CTO, coconut shell, 1000 iodine”)
• Target annual volume
• Packaging requirements (neutral bag / color box / blister)
• Certifications needed (NSF marking on label, SGS test report, etc.)
• Destination port

Specify FOB Ningbo as your baseline. Add CIF only after confirming current freight rates with your forwarder.
