A new air purification technology – which can dramatically improve in-door air quality – has been developed in Hong Kong by a senior engineering lecturer at City University.
Dr Oscar Hui Kwan-san said in a press release on Thursday that the latest purification technology was a major step towards developing a new generation of home-use air cleaners.
Hui, who helped develop the new technology, said it transformed dangerous air pollutants into “harmless substances”.
It was different to other air purifiers because they still absorbed harmful materials in the atmosphere, Hui explained. The new technology was more efficient and environmentally friendly.
Hui said his research team had recently received HK$1 million from the government’s backed innovation and technology fund. It obtained another HK$200,000 from private firms to develop a prototype air purifier.
He said the new technology could remove 92 per cent of volatile organic compounds (VOCs) in the atmosphere. These account for the majority of the in-door air pollutants.
