SEOUL, Nov. 21 (Korea Bizwire) — A district in Seoul has introduced a sidewalk air pollution shelter for the first time in the country.
Seoul’s Gangnam District on Wednesday installed a “fine dust free shelter” at the bus stop in front of the Galleria Department Store on a trial base.
The facility removes more than 90 percent of fine dust using electric air purifiers and activated carbon to clean up the outside air, while bringing in purified air to maintain the concentration of fine dust inside the facility at a “good” level.
A three-stage sliding door was installed at the entrance of the shelter to block the inflow of fine dust from outside.
Inside the shelter, hot seats, air-conditioning and heating machines, indoor and outdoor fine dust monitors, solar energy facilities and guide boards for fine dust measurement data were set up.
“We are planning to build additional laminar-flow, uniform air-generator, type shelters at other bus platforms by the end of this year and expand the installation of the shelters to areas where there is a lot of travel,” an official from the district said.

Meanwhile, Gangnam also carried out a project to remove sewage odor in the summer of this year in order to become a leading model for green cities, following it’s top rank in educational, residential and living areas.
The smell of sewage is spread throughout the city through rainwater on nearby roads and from manholes as sewage from pumping-type purifiers flows through public sewage pipes.
In response, the district’s sewage decontamination team installed a “cavitator+SOB(Sulfur-Oxidizing Bacteria) media” in the cleanup tank to remove bad smells by supplying oxygen to residential areas near Garosu-gil in Sinsa-dong for about a month from May.
Authorities also installed a variety of sewage odor-reducing devices, such as spray-damping, pillar-type odor-blocking facilities, manhole deodorant, fall-relief facilities and manhole inverts.
