Keeping Manufacturing
Since 1999, Keeping has specialized in air purifier OEM/ODM manufacturing. Based in Shenzhen, our factory is equipped with multiple automated production lines, with monthly production capacity that meets high-volume order fulfillment. As an experienced air purifier source factory, we serve the diverse needs of global customers with large-scale production capabilities and rapid delivery response. We are not a generic contract manufacturer — we make air purifiers, and that is all we do.
Quality Control System
At the heart of Keeping's manufacturing philosophy is an unwavering commitment to quality. We have established a comprehensive quality control system that rigorously oversees every stage of production — from incoming material inspection and in-process sampling to final product testing, with multiple layers of checks ensuring outstanding quality.
Incoming Material Inspection
All materials are inspected to AQL standards before use, with supplier reports cross-verified by our lab — non-conforming materials never reach the line.
In-Process Control
QC patrols and real-time MES tracking ensure unit-level traceability, with any anomaly triggering an immediate line stop — we never produce, pass, or accept defects.
Final Product Inspection
Every unit undergoes full performance, safety, and run-in testing by an independent QC team — only units that pass are shipped, backed by complete batch records.
Smart Automated Production Lines
Our automated assembly and inspection lines handle every critical process — from filter encapsulation to final run-in testing. This ensures exceptional product consistency, shortens lead times, and enables high-volume rush orders. With MES-driven digital management, every unit's production journey — from work order to warehouse — is fully transparent and controllable.
