Filter Cotton

Every batch of our adult protective mask is put through rigorous, independent testing before it ever reaches the shelf, and the results are backed by documentation you can actually rely on. Our products are manufactured and verified in full compliance with GB 2626-2019 - the official Chinese national standard governing self-priming filtering respirators intended for protection against airborne particulate hazards. This standard defines the minimum performance benchmarks that the entire product line is held to, ensuring that filtration performance, breathing resistance, field of vision, and structural strength all meet a recognized, enforceable threshold.

The certification reports are not produced in-house. They are issued by GTTC (Guangdong Testing Institute of Product Quality Supervision), an established third-party laboratory with long-standing expertise in personal protective equipment testing. What makes these reports carry weight is GTTC's own accreditation stack: it holds CNAS (China National Accreditation Service for Conformity Assessment), CMA (China Metrology Accreditation), and ilac-MRA (International Laboratory Accreditation Cooperation Mutual Recognition Arrangement) credentials. In practical terms, that means the test data recognized by GTTC is mutually accepted across a network of internationally accredited laboratories, not limited to domestic Chinese scrutiny.

For overseas buyers, this matters directly: it translates into traceable, defensible paperwork that can be submitted to customs, importers' compliance teams, and end-user safety audits. It also signals that the KN95 claims on the label are not marketing language - they are the outcome of a structured test protocol overseen by an accredited, independent body, with the report reference available for verification.
