Air Quality Index (AQI) in Vietnam 🇻🇳
Live Air Quality Index (AQI) and PM2.5 Levels in Vietnam
Currently, the Air Quality Index (AQI) in Hanoi, the capital of Vietnam, is measured at a score of 155. According to the US EPA health standard, this air quality rating is categorized as Sensitive. The current atmosphere in Hanoi is influenced by a PM2.5 (fine particulate matter) concentration of 60.8 µg/m³ and PM10 levels recorded at 61.7 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 45.4 µg/m³.
Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Vietnam based on industrial output, traffic density, and local weather patterns. Real-time pollution data and respiratory health alerts are also being actively monitored in cities like Ho Chi Minh City, Da Nang, Haiphong, Biên Hòa and Cần Thơ. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.

Understanding Air Quality Levels
Air is fresh and healthy. Safe for all outdoor activities.
Acceptable air quality, though sensitive groups should monitor comfort.
Vulnerable groups (children, elderly) should limit outdoor exertion.
Everyone begins to experience health effects. Stay indoors where possible.
Significant health impact for entire population. Emergency conditions.
Serious health alert: everyone may experience serious life-threatening effects.
Fine particles are at minimal, safe levels. Air is optimal.
Acceptable air, but haze may be present in urban areas.
Individuals with heart or lung disease should limit activity.
Particulate levels high enough to cause respiratory irritation.
Heavy haze. High risk to cardiovascular health for the public.
Lethal particulate concentrations. Critical neurological and lung risk.
Low levels of dust and coarse particles. Environment is safe.
Coarse particles may trigger coughing in sensitive groups.
Visible dust pollution. Sensitive groups should avoid heavy labor.
Widespread respiratory impacts likely for the population.
Dangerous dust and debris levels. Significant warnings issued.
Extremely high concentrations. Stay inside with filtration.
Surface ozone levels are within a safe, natural range.
Acceptable air, but sensitive individuals may feel chest tightness.
Rising ozone can trigger airway inflammation in active children.
Avoid heavy outdoor work during the hottest part of the day.
Serious lung function reduction likely across the public.
Emergency ozone levels. Risk of permanent lung tissue damage.
Nitrogen levels are optimal. Safe for everyone.
Typical background levels for high-density urban areas.
Increased risk of respiratory infections for vulnerable groups.
Significant airway inflammation likely near traffic zones.
Acute respiratory distress potential. High-risk groups stay indoors.
Toxic concentrations. Immediate health precautions required.
Carbon Monoxide levels are clean and non-toxic.
Acceptable; may affect those with specific heart conditions.
Reduced oxygen delivery to the heart may occur.
Headaches and fatigue may occur in urban canyons.
Significant cardiovascular distress. Mental confusion possible.
Lethal potential. Immediate risk of neurological collapse.
Optimal air quality with no sulfur detection.
Acceptable air; minor odors possible near industry.
Bronchoconstriction possible for active asthmatics.
Respiratory distress likely for the wider population.
