1. Certifications

What does it mean to be TGA Approved?

All KATOJI products are registered with the Therapeutic Goods Administration of Australia (TGA). The TGA is regulated by the Department of Health under the Australian Government, acting as a regulatory body for therapeutic goods (e.g. medical devices & gene technology). TGA standards are regarded as one of the highest and most stringent certifications, recognised internationally. Therefore, you can be assured that all our products are rigorously tested and meet safety standards. (ARTG Identifier: 341877)

What does it mean to be ISO 13485:2016 & ISO 9001:2015 Certified?

The International Organisation for Standardization (ISO) is a regulatory body which sets standards that are agreed upon by international experts. The organisation aims to regulate international standardization in industries such as manufacturing. We currently hold both ISO 13485:2016 & ISO 9001:2015 Compliance Certificates.

2. Products

What is a melt-blown filter?

Making melt-blown filters involves a complex process of melting and blowing polymers into fine fibres, creating layers of webs tight enough to capture nanoparticles. Those ultra-fine fibres are bonded and collected on a moving screen, becoming sheets of webs that are ultimately the 'filters' used in our masks. Because of how tightly these sheets are bonded together, they have the ability to filter out particles as small as viruses!

Are KATOJI products fluid resistant?

Yes! High quality melt-blown filters are used in all our products, making them fluid resistant to offer optimal protection during all-day usage.

Where are KATOJI  products manufactured?

Our products are made in a certified manufacturing site in Vietnam. We adhere to all safety regulations set out by the International Organisation for Standardization (ISO) and have obtained ISO 13485:2016 & ISO 9001:2015,CE,QCVN Certifications to ensure all our products are tested under stringent Quality Management Systems.
