About the company

A specialist, not a generalist.

One product family — air purification — covered in depth, from filtration research to export trade.

Dongqi Industrial focuses on one product family — air purification — and covers it in depth. From filtration research and CADR performance engineering to industrial design, compliance and export trade, we take air purifiers from concept to market-ready product.

Based in San Po Kong, Kowloon, we work with manufacturing partners in the Greater Bay Area and serve brand owners and distributors selling into North America and other regulated markets.

Our team combines hardware engineering backgrounds with hands-on experience in North American certification and retail requirements, which lets us design for the destination market from day one rather than retrofitting compliance at the end.
