Founder's Quotations

Our founder is Law. In his early years, he was engaged in selling air purifiers in Hong Kong. The year 2003 coincided with the spread of SARS virus, and Hong Kong was also plagued by the virus, which seriously threatened people's lives and safety. Law realized that the safety of air determines the health of human life, and the air purifier he acted for could only purify the air simply, rather than disinfect the air all the time. Therefore, Law searched for various air disinfection products in the market, but he found that many of them could only be used in an empty space, where man and machine could not coexist. So Law continued to search on the Internet and finally realized the bipolar Ionization technology.

This is a kind of nature's self-purification technology, whenever after the lightning storm, the air is always so fresh and clean and pleasant, the secret is the high-pressure lightning, breakdown the vapour、oxygen in the air, so that it is decomposed into positive and negative ions floating in the air, so as to purify and disintegrate. Bipolar ionization air purification technology is a perfect replica of this "gift" of nature. Therefore, Law returned to the mainland from Hong Kong, strengthened his confidence in the air purification and disinfection industry, committed to reducing the spread of viruses and making modest contributions to the human society, and started his own entrepreneurial journey.
