MOQ for standard 10" PP, CTO and GAC cartridges starts at 1,000 pcs per SKU for stock items, 3,000 pcs for OEM-printed sleeves, and 5,000 pcs for fully customized ODM moldings (private end-cap, custom O-ring, branded shrink-wrap). UF membranes and RO 75/100/400 GPD membranes typically MOQ 500 pcs. Wall-mounted dispensers MOQ 100 units. Smaller trial orders are negotiable for new distributors.
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.
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. Wall-mounted 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.
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%.
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.
