Custom Water Filter OEM — FAQ
Q1. What is the MOQ for OEM water filter production?
It depends on the category: standard PP/CTO cartridges are negotiable, Everpure-compatible and custom housings start at 500 pcs, RO membranes at 200 pcs, complete systems at 50 pcs. Private-label branding (logo printing, custom packaging) typically starts at 500 pcs per model.

Q3. Do you offer custom mold tooling for new filter housing designs?
Yes — custom mold tooling is one of our core capabilities. We design and build injection molds in-house for filter housings, filter heads, and cartridge shells. Mold cost depends on complexity (typically $3,000–$15,000). Typical timeline: mold design 5–7 days, mold fabrication 25–35 days, first article samples within 40 days from drawing approval.

We produce big blue housings (10" and 20"), standard slim housings, clear/transparent housings, high-flow commercial housings, stainless steel housings, and FRP pressure vessels. Materials include food-grade PP, ABS, SAN (for clear units), and 304/316 stainless steel. All housings are pressure-tested to 1.5× rated working pressure.
