The Problem – Air Quality
The construction of a new school campus in Kowloon, with the accompanyinginterior decoration and purchase of new furniture created a scenario where the indoor air was contaminated with volatile organic compounds (VOCs). These harmful pollutants radiate toxic odours and not only affect the learning ability of students but also endanger the health & wellbeing of both staff and students alike.

The Solution – NCCO
Initially the school conducted a trial through the installation of eight ceiling-mounted NCCO air purifiers. The NCCO air purifiers were designed to combat the specific issues the school was facing whilst also addressing the high levels of pollution experienced generally in Hong Kong.
As a result of the NCCO technology positive impact on indoor air quality was instantly recognised to an exceptionally high level (recorded in EPD IAQ Reference).
Following the successful trial, the school immediately purchased a further 73 units which were positioned throughout the campus, creating a safe environment, happy, productive and attentive pupils who achieved excellent attendance and performance statistics.
