The Problem

The public toilets in the passenger terminals are used by millions of people every day. They expelled a strong odour that impacted passengers and nearby businesses.

The Solution

Approximately 300 NCCO air purifiers were installed in 108 public restrooms in Passenger Terminal 1.

This dramatically reduced the concentration of ammonia, volatile organic compounds (VOCs), and bacteria in the air,  producing an immediate noticeable improvement in Air Quality.

Additionally, it made commercial sense due to the lower operational costs as a result of the reduced energy consumption required for air-conditioning and extraction.
