LU develops and distributes air purifiers to over 1,000 subdivided flats
The Lingnan Entrepreneurship Initiative (LEI) of Lingnan University has developed a low-cost mini air purifier proven to be effective in reducing the indoor concentration of fine particulate matter (PM 2.5) by 80 per cent to less than 5 μg/m3.
It provides an improvement in the air quality of subdivided flats – one of Hong Kong's main social and humanitarian issues – that meets the World Health Organization (WHO) 2021 Global Air Quality Guidelines, said Prof Albert Ko Wing-yin, Director of LEI.
The most distinctive features of the air purifier, which addresses the needs of subdivided flat residents, are its efficiency, small size and low power consumption, he added.
In December, the LEI, together with the Sham Shui Po District Office of Home Affairs Department and Sham Shui Po Residents Association Limited, arranged for volunteers to distribute 1,000 air purifiers free to families living in sub-divided units before Christmas.
At the initiative launching event, some 100 subdivided flat residents were invited and assembled the air purifiers under the guidance of LU faculty members and students.
Also in December, LU showcased the collaborative efforts of students, engineers, doctors, and social workers in developing new products and services based on existing technology to solve social problems from an all-round perspective at the InnoTech Expo 2022 in the Hong Kong Convention and Exhibition Centre.
