What You'll Learn
Wear masks and use air purifiers
Seoul, South Korea's largest city, has the worst levels of air pollution of the 35 richest countries in the OECD. The air pollution in Seoul is so bad that it has been linked to premature deaths and a decrease in life expectancy. To deal with the pollution as a foreigner, you can wear masks and use air purifiers.
Wearing masks is a popular and affordable method for protection against air pollution in Seoul. Masks like the 3M N95 are very affordable and top-performing masks for protection against Particulate Matter (PM2.5 Air Pollution). The N95 label means that the mask can filter out at least 95% of airborne particles larger than 0.3 microns. Other masks include the Vogmask, which uses microfiber filtration fabric to provide an N99 rating. The Respro mask is also a good option, especially for biking in heavy traffic. When wearing masks, it is important to ensure a good "fit" with the face to ensure efficiency.
Air purifiers are another way to deal with air pollution in Seoul. Air purifiers work by actively filtering out harmful particles from the air, thus reducing exposure to indoor pollutants. When selecting an air purifier, it is important to consider factors such as the size of your living space, the specific pollutants you want to target, and the purifier's Clean Air Delivery Rate (CADR).
It is important to combine these indoor and outdoor strategies to reduce exposure to air pollution and safeguard your health. Additionally, the Korean government is taking action to improve air quality in Seoul by providing air purification systems for public facilities and schools and implementing the Special Act on Seoul Metropolitan Air Quality Improvement.

Avoid outdoor activities on high pollution days
Seoul has some of the worst air pollution in the world, and it is distressingly common for the city's Air Quality Index (AQI) to cross 150, a level classified as 'very unhealthy'. On such days, the health impact of breathing the air in Seoul is equivalent to smoking over ten cigarettes. Even on a 'normal' day, the impact is similar to smoking six cigarettes.
To protect yourself on high pollution days, it is best to avoid outdoor activities. This is especially important for children and future generations, as well as those with pre-existing health conditions. A popular, affordable method for protection is the use of pollution masks, which are widely available and commonly worn in Korea. You may also want to invest in an air purifier for your home, which is another common method Koreans use to breathe cleaner air.
It is also important to stay informed about the air quality and understand its implications. There are many apps and websites that can help you monitor the AQI in Seoul, and it is a good idea to check these before planning outdoor activities. The air quality tends to be worse on days with high vehicle use, so try to plan outdoor activities for days when the government has banned heavy vehicles and old, diesel-using vehicles. You can also take advantage of Seoul's many bicycle routes, pedestrian-only zones, and parks to explore the city while limiting your exposure to vehicle emissions.
Finally, be aware of the physical symptoms of poor air quality, such as nausea, and adjust your activities accordingly. If you start to feel unwell, it is best to move indoors or wear a mask if you need to remain outside.

Use public transport or bicycles instead of cars
Seoul's air pollution is a serious issue, and it is important for foreigners visiting or living in the city to take steps to protect themselves and help improve the situation. One of the most effective ways to reduce air pollution in Seoul is to use public transportation or bicycles instead of cars.
Seoul, South Korea's largest city, has the worst levels of air pollution in the country. The city's air quality has been linked to health problems and a reduced life expectancy for its residents. According to the University of Chicago's Energy Policy Institute (EPIC), the average Seoul citizen can expect to lose approximately 1.4 years of life expectancy due to poor air quality. Therefore, it is crucial to take measures to improve the air quality and reduce the health risks associated with air pollution.
Using public transportation or bicycles instead of cars is a simple yet impactful way to reduce air pollution in Seoul. Cars, particularly those with internal combustion engines, are a significant source of air pollutants and greenhouse gas emissions. By opting for public transportation or bicycles, you can help reduce the number of cars on the road and decrease the overall emissions contributing to air pollution.
Seoul has an extensive public transportation system that includes buses, subways, and trains. These options provide efficient and convenient ways to get around the city without relying on private cars. The South Korean government has also implemented initiatives to encourage the use of public transportation, such as providing free public transportation during periods of high pollution. Additionally, the government is working to improve air quality on public transportation by replacing diesel buses with natural gas vehicles and equipping cars with emission-reduced devices.

Stay informed about air quality and health risks
Air pollution in Seoul is a serious issue with far-reaching health consequences. It is important to be aware of the air quality and the associated health risks when living in or visiting Seoul.
There are several ways to stay informed about air quality levels and potential health risks. Firstly, it is important to understand the Air Quality Index (AQI) and the associated health implications. The AQI is a measurement of air quality that takes into account various pollutants, and it is used to communicate the level of pollution in the air. In Seoul, it is not uncommon for the AQI to exceed 150, which is classified as 'very unhealthy' by the American Environmental Protection Agency. On days when the AQI reaches this level, breathing the air is equivalent to smoking more than ten cigarettes. Even on days with 'normal' air quality, the health impact can be similar to smoking six cigarettes. Therefore, it is crucial to monitor the AQI regularly to understand the severity of air pollution on a given day.
Several sources can be used to obtain up-to-date information on Seoul's air quality. The South Korean government has made long-term air quality data publicly available, and this data can be accessed through official government websites or mobile applications. These sources will provide detailed information on pollutant levels, including PM2.5 and PM10 particulate matter, which are of particular concern in Seoul. Additionally, the World Air Quality Report, published annually, provides a comprehensive overview of air quality in cities worldwide, including Seoul. This report includes data on average annual PM2.5 concentrations, which can be useful for understanding the city's air quality trends over time.
It is also essential to be aware of the health risks associated with air pollution. Air pollution has been linked to various health issues, including respiratory problems, heart disease, stroke, and lung issues. A study by the University of Chicago's Energy Policy Institute (EPIC) found that the average South Korean can expect to lose approximately 1.4 years of life expectancy due to poor air quality. In Seoul specifically, residents may lose up to 1.7 years of life expectancy if pollution levels are not improved. Therefore, understanding the potential long-term impacts on health is crucial for both short-term visitors and long-term residents of Seoul.
Staying informed about air pollution in Seoul also involves recognizing the sources of pollution and the measures being taken to address them. Seoul's air pollution has various sources, including domestic factories, vehicle emissions, and power plants.
