The GAC / UDF filter cartridge uses granular activated carbon to reduce chlorine, odor and unpleasant taste before or after fine filtration stages. It is commonly installed in RO systems, water purifiers, dispensers and multi-stage cartridge sets. The cartridge can be built with coconut shell carbon, PP shell, non-woven pads and optional mesh or sponge protection. OEM buyers can customize carbon grade, cartridge length, cap design, label, bag, color box and master carton for wholesale replacement programs. Main specifications include Media: Granular activated carbon; Shell: Food-grade PP; Length: 10 inch / 20 inch. Yuchen Water supports private label, filter labels, export cartons and OEM/ODM configuration by order plan.

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.
