Air-Purifier Machine for Sub-divided Households

 

In January 2018, students from the Service-Learning course PSY3103 Psychology of Human Performance and Technology visited families living in Sham Shui Po’s sub-divided flats to experience the challenges the families face each day.

The students identified poor air quality as a pressing challenge influencing tenants’ quality of life. By applying academic knowledge, simple technology and design thinking, students brainstormed and came up with the idea to design a low-cost air purifier after carefully considering the households’ affordability and the setting of the tiny living environment. The prototypes were then tested in order to be further modified for enhancement.

With the support of the Lingnan Entrepreneurship Initiative (LEI), staff and students designed and developed an effective low-cost air purifier to improve the living conditions of those living in Hong Kong subdivided units (SDUs). Guests and residents in SDUs in Sham Shui Po helped to compose the low-cost air purifier in December 2022 for distributing 1,000 units of air purifiers to occupants of SDUs. Research about Air Quality in the subdivided units was conducted in 2023 to know more about the effectiveness of the low-cost air purifier.
