About Us

RHT Industries Limited is a leader among environmental engineering companies. Founded in 1998, the company is committed to the research and development of technology that protects both the environment and human beings. The company has grown side by side with Hong Kong, providing comprehensive and effective air purification services to public institutions and private enterprises. With an outstanding scientific research team and talented experts, we have applied our multi-nationally patented technology, Nano Confined Catalytic Oxidation (NCCO), to both our products and the company’s name. Starting with air purification and personal care, our in-depth development in both commercial engineering and home life can offer you cleanliness in your living environment.

b-MOLA is a subsidiary line of RHT Industries, specializing in household air purifiers, and uses the Ocean Sunfish (Mola) to represent the brand.

What is NCCO?

氧聚解NCCO (Nano Confined Catalytic Oxidation) 技術由香港科研團隊開發,擁有多國專利,是體現嶄新科學思維的前沿空氣淨化技術。 珍貴天然的火山岩擁有優秀的污染淨化能力,技術人員從中得到啟發,利用最新科技仿造出相同結構的顆粒狀反應層,並配合「尖端納米技術」及「活氧作用」過濾並分解污染物,奠定了此項專利技術的基礎。 

Compared with general air treatment technology, which can only absorb pollution but cannot decontaminate it, NCCO realized the absorption and purification of pollutants in one system, so that the dirt will not accumulate in the machine to cause secondary pollution, and the life of the filter reaction layer is extended to 12 years. It solved the short life of the filter screen, which was criticized by the market for air purifiers, and brought users a more convenient and safer air purification method.

In terms of retail, our company has successively launched RHT and b-MOLA brands of household air purification products, maintaining success in the Hong Kong market.
