Standards we work to
Honest documentation, not marketing labels. Below is the actual quality and verification stack that ships with every batch.
Made-in-China Verified
Verified supplier on Made-in-China.com since 2010 — independent verification of company, capacity, and trading history.
NSF-certified raw materials
Activated carbon (GAC and CTO block) and key filter media sourced from suppliers with active NSF certification — independent food-contact safety verification.
100% in-house QC
Every unit passes leak test and 2.8 MPa burst pressure test. Batch-level filtration capacity sampling. Test reports ship with every shipment.
Food-contact documentation
Material safety + food-contact substantiation files for every component touching drinking water (PP, housing, membrane, carbon).
EAC support
Technical files prepared per TR CU 010/2011 so your local lab or certification body can issue the EAC declaration efficiently.
ISO 9001 — quality system
Production runs on ISO 9001:2015 principles (prior certificate lapsed; recertification underway). Internal audits run continuously.
