[Asia Economy (Daejeon) Reporter Jeong Il-woong] Daejeon City announced on the 30th that it has installed 421 air purifiers at all 22 stations on Line 1 of the urban railway to improve air quality at the stations.


Additionally, the city has established a smart air quality management system by linking the air purifiers installed in the stations with automatic air quality measuring devices on the platforms.


The smart air quality management system automatically operates the air purifiers based on the fine dust concentration measurements from the precise automatic air quality measuring devices, instead of the less accurate sensors in the air purifiers, thereby removing fine dust.


Meanwhile, the city plans to upgrade the filter devices of all underground station air conditioning units to high-performance devices capable of removing fine dust by the end of this year, and also install air quality improvement devices in the train cars.


The city expects that once the series of underground station air quality improvement projects are completed, the fine dust concentration will decrease by 2.9㎍/㎥ compared to the previous year by the end of this year.



Sung Gi-moon, head of the Tram Urban Metropolitan Headquarters, stated, “To address the fine dust issue, we plan to carry out the underground station air quality improvement projects annually until 2022,” adding, “Through these improvement projects, citizens will be able to use the urban railway in a more comfortable environment.”
