RHT

RHT is an environmental technology company founded in 1998 and headquartered in Hong Kong. For over two decades, the company has focused on developing practical solutions that improve the quality of the air we breathe, both indoors and out.
Working closely with the Hong Kong University of Science and Technology (HKUST), RHT has transformed breakthrough research into reliable products that serve a wide range of industries. From compact air purifiers for homes to large-scale filtration systems for commercial and public spaces, their product range is built to tackle air pollution at every level.
At the heart of RHT’s innovation is its Nano-Confined Catalytic Oxidation (NCCO) technology – a patented air purification method that goes far beyond traditional filters. It doesn’t just trap harmful pollutants like VOCs, bacteria, odours, and ammonia – it breaks them down at a molecular level, helping to maintain clean, healthy air with minimal maintenance.
Today, RHT’s NCCO systems are used in offices, hospitals, hotels, schools, shopping malls, public transport stations, and even in demanding sectors such as the automotive and printing industries. Wherever air quality matters, RHT provides a proven and effective solution – designed for real-world environments, not just laboratories.
