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?
The NCCO (Nano Confined Catalytic Oxidation) technology is developed by a Hong Kong scientific research team and has patents in many countries. It is a cutting-edge air purification technology that reflects new scientific thinking. The precious natural volcanic rock has excellent pollution purification ability, and the scientists are inspired by it. They use the latest technology to imitate the granular reaction layer of the same structure, and cooperate with advanced nanotechnology and active oxygen to filter and decompose pollutants. the basis of this patented technology.
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.
