Our factory operates under the authoritative ISO9001, ISO14001 and ISO45001 management systems. We implement full-process quality control, covering raw material inspection, in-production monitoring and finished product testing, to maintain stable and consistent product quality.

Before production, all filter materials are strictly checked for filtration efficiency, air permeability and durability. During manufacturing, our professional QC team performs regular sampling, size calibration and appearance inspection to eliminate defective goods. Every batch of air filters undergoes strict performance testing before delivery.

All products comply with international standards with RoHS certification. We also support third-party testing and provide complete qualification documents, ensuring all products meet export and customized quality requirements.
