UF membranes and RO 75/100/400 GPD membranes typically MOQ 500 pcs. ▣ dispensers MOQ 100 units. Smaller trial orders are negotiable for new distributors.

Where is your factory located and can buyers visit?

Our manufacturing center is in Yuanhua Town, Haining City, Zhejiang Province, China — approximately 90 minutes by car from Shanghai Hongqiao Airport (SHA) and Hangzhou Xiaoshan Airport (HGH). The 20,000+ m² facility houses dedicated PP melt-blown extrusion lines, sintered carbon block presses, UF/RO membrane assembly clean rooms, and dispenser SMT/assembly lines. We welcome scheduled buyer visits, third-party inspections (SGS, BV, TÜV) and OEM qualification audits.

What lead time should I expect for bulk orders?

Standard PP, CTO, GAC and T33 cartridges in stock colors ship within 7–10 days. OEM private-label cartridges with custom printing: 20–25 days from artwork approval. RO/UF membrane elements: 15–20 days. ▣ and desktop dispensers: 30–45 days depending on customization. Container loading typically 1 × 20'GP (≈ 80,000 cartridges) or 1 × 40'HQ (≈ 200 dispensers). FOB Shanghai or Ningbo; CIF, CFR and DDP terms available.

Do you supply RO membranes for both residential and commercial use?

Yes. We offer full-range reverse osmosis membranes: 50 GPD, 75 GPD, 100 GPD, 200 GPD, 400 GPD, 600 GPD for under-sink residential systems, plus 300 GPD, 400 GPD and 600 GPD high-rejection elements for light commercial water dispensers. Industrial 4040 and 8040 elements (BW30, SW30 equivalents) are available for water treatment plants, dialysis, semiconductor rinse and pharmaceutical applications. Salt rejection rate ≥ 96–99%.

What is the difference between PP melt-blown, CTO carbon block and GAC granular activated carbon filters?

PP melt-blown sediment filters use thermally-bonded polypropylene fibers to remove particulate contaminants (rust, sand, silt) from 0.5 to 50 microns. CTO (Chlorine, Taste & Odor) sintered carbon block filters use compressed coconut-shell or coal-based activated carbon to remove free chlorine, chloramines, VOCs, pesticides and improve taste — typical 5 µm or 10 µm. GAC granular activated carbon filters use loose carbon granules for higher contact-time chlorine adsorption and are often the second stage in 5-stage RO systems. We manufacture all three at industrial scale with full traceability.

Do you provide OEM/ODM customization for water dispensers and purifiers?

Absolutely — OEM/ODM is our core specialty. We customize: outer shell color (Pantone matching), front-panel logo silk-screen or laser engraving, LED display language and UI, voltage (110V/220V/240V), plug type (US/UK/EU/AU), packaging (gift box, brown carton, color sleeve), user manual translation, and bundled accessory kits. Tooling cost for new injection molds is typically refundable on order volumes ≥ 5,000 units.

What payment terms and trade terms do you accept?

Standard terms: 30% T/T deposit on order confirmation, 70% balance against B/L copy before shipment. We also accept L/C at sight from prime banks, Western Union and PayPal for sample orders ≤ USD 3,000, and Alibaba Trade Assurance for first-time buyers. Trade terms: EXW Haining, FOB Shanghai/Ningbo, CIF, CFR, DDP and DDU available depending on destination port and incoterm preference.

What is the typical lifespan of your filter cartridges?

Expected service life depends on inlet water quality and daily flow: PP melt-blown sediment filter — 3 to 6 months; CTO carbon block — 6 to 12 months; GAC granular carbon — 6 to 12 months; T33 post-carbon — 12 months; UF ultra-filtration membrane — 24 to 36 months; RO membrane element — 24 to 36 months; mineralization / alkaline T33 — 12 months; cation-resin softening cartridge — 6 to 12 months depending on water hardness. Replacement reminder LED is built into all our smart dispenser models.

Do you provide reverse osmosis system technical support and after-sales service?

Yes. Every OEM partner receives: complete technical drawings (PDF/DWG), assembly manuals, installation videos, multilingual user manuals (45+ languages available), spare parts list with PN codes, dedicated WhatsApp/email engineering support, and 12 to 24-month limited warranty on housings, membranes and electronic components. On-site engineer dispatch is available for large industrial RO plant commissioning at additional cost.

Can your filter housings handle high-pressure industrial applications?

Yes. We manufacture SUS 304 and SUS 316L food-grade stainless steel filter housings rated up to 16 bar (232 psi) working pressure, with 1", 1.5", 2" and 3" NPT/BSP inlet/outlet options. Big Blue 20" and 30" housings in reinforced PP with brass-insert threads handle up to 8.6 bar (125 psi). All pressure vessels are hydrostatically tested at 1.5× rated pressure before shipment and come with a CE PED 2014/68/EU declaration where applicable.

What raw materials and filter media do you source?

We use food-grade materials and provide selected material declarations on request: virgin polypropylene resin (no recycled PP) for melt-blown and housings; coconut-shell activated carbon (≥ 1100 mg/g iodine value) and bituminous coal carbon for CTO/GAC; PVC and PES hollow-fiber for UF membranes; thin-film composite (TFC) polyamide for RO membranes; food-grade silicone for O-rings; SS 316L for sanitary fittings; FDA-approved ABS and PP for housings; LG Display panels for smart dispensers; certified copper heating elements (where applicable).
