1. What is Air Pollution Index?

The air pollution index, also known as the Air Quality Index (AQI), is a technical parameter converted from the concentrations of major air pollutants. This index serves as a simplified measure to warn the community about air conditions and the potential level of impact on human health.

Simply put, the AQI is an alarm bell for your respiratory health. It converts complex data on the concentrations of various pollutants into a single number, an easy-to-remember scale, and color codes. The higher the AQI, the worse the air quality.

2. Factors measured in the Air Quality Index

The U.S. Environmental Protection Agency (EPA) determines the Air Quality Index (AQI) based on five key air pollutants:

• PM2.5 Fine Dust: Ultra-fine particles with a diameter ≤ 2.5 microns. This is often the main pollutant in major Vietnamese cities. They originate from vehicle emissions, industrial activities, straw burning, and construction. PM2.5 can penetrate deep into the lung alveoli and even enter the bloodstream, causing serious respiratory and cardiovascular diseases.
• PM10 Fine Dust: Particles with a size ≤ 10 microns. Although less dangerous than PM2.5, they can still cause irritation to the eyes, nose, and throat.
• Ozone (O3): A gas formed from chemical reactions under sunlight. Ground-level ozone is a harmful substance that irritates the respiratory tract, causing coughing and chest tightness.
• Nitrogen Dioxide (NO2): Comes mainly from fuel combustion processes (vehicles, power plants), causing pneumonia and exacerbating asthma.
• Sulfur Dioxide (SO2): Emitted from burning coal and oil, causing respiratory problems and the formation of acid rain.

3. AQI Scale analysis & meaning

The AQI scale is divided into levels with intuitive color codes, helping you easily recognize air conditions:

• Good (0 – 50) – Green: Air quality is satisfactory, air pollution poses little to no risk.
• Moderate (51 – 100) – Yellow: Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
• Unhealthy for Sensitive Groups (101 – 150) – Orange: Members of sensitive groups may experience health effects. The general public is less likely to be affected.
• Unhealthy (151 – 200) – Red: Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.
• Very Unhealthy (201 – 300) – Purple: Health alert: The risk of health effects is increased for everyone.
• Hazardous (>300) – Maroon: Health warning of emergency conditions: Everyone is more likely to be affected

Besides this 6-level system, some countries use their own systems. In South Korea, the Comprehensive Air-quality Index (CAI) is divided into 4 levels: Good – Moderate – Unhealthy – Very Unhealthy. In the United Kingdom, parameters are measured separately and divided into 10 levels (1 to 10) for environmental researchers and the public to monitor in the most specific and understandable way.

4. Checking the Air Pollution Index

You can easily track the AQI in your living area through the following tools:

4.1. Mobile Applications

• AirVisual (IQAir): Provides real-time data, AQI forecasts, and city pollution rankings.
• Plume Labs: User-friendly interface, provides the “best time of day” index for going outside.
• Weather Apps: Apps like Weather Underground or Apple Weather have integrated AQI indices.
• Puritrak’s AirNow Air Quality Management System: Allows accurate real-time monitoring of both indoor and outdoor air quality.

• WAQI.info: An open community project providing real-time data from monitoring stations worldwide.
• Vietnam’s Environmental Monitoring Portal (by the Vietnam Environment Administration): Provides official data from domestic monitoring stations.

5. Health protection measures according to AQI levels

• Yellow (Moderate): Sensitive groups should limit prolonged outdoor activities.
• Orange (Unhealthy for Sensitive Groups): Sensitive groups should limit outdoor exposure. The general public should reduce heavy outdoor activities.
• Red (Unhealthy), Purple (Very Unhealthy), and Maroon (Hazardous):
  • Limit going outdoors: Everyone, especially sensitive groups, should stay indoors.
  • Close windows: Prevent polluted air from entering the house.
  • Use air purifiers: Choose a purifier with a HEPA filter to effectively remove PM2.5 fine dust.
  • Wear standard masks: When going outside is necessary, use N95/KN95 masks or medical masks capable of filtering fine dust.

1. Causes of the air pollution season

Air pollution is a significant alteration in the composition of the air, primarily caused by the introduction of smoke, dust, fumes, or other foreign gases, leading to unpleasant odors and direct health impacts. This phenomenon becomes more severe during the final and initial months of the year, creating a distinct air pollution season.

Numerous factors contribute to air pollution, stemming from both human-made (anthropogenic) and natural sources.

The primary causes can be divided into two main groups:

Natural Causes

• Seasonal transition and Temperature inversion: During seasonal changes, temperature inversions occur frequently, trapping pollutants at a low altitude and preventing their dispersion.
• High humidity and drizzle: High humidity levels and misty rain can contribute to the accumulation of particulate matter.
• Pollen and mold spores: Natural emissions from plants, such as pollen and mold spores.

Human-Made Causes

• Vehicle emissions: A major source of PM2.5 fine dust, NO2, and CO.
• Industrial production: Factories and industrial zones emit enormous amounts of SO2, CO2, and heavy metal dust.
• Burning of waste and agricultural debris: The burning of trash, straw, and other agricultural waste generates a massive amount of smoke and dust in a short period.
• Construction and demolition: These activities produce large quantities of dust, including hazardous fine particulate matter.

2. Current Status of the Air Pollution Season Situation

The situation of the air pollution season in major urban areas like Hanoi and Ho Chi Minh City has reached alarming levels:

3. How to recognize air pollution

Air pollution levels can vary by location and time of day. Here are some simple ways to identify air pollution conditions:

• Check information: You can monitor the AQI (Air Quality Index) through weather apps or local news sources.
• Assess your surroundings: Do you live near industrial zones, power plants, or busy traffic roads? If so, your risk of exposure to polluted air is very high. Emissions and dust levels from manufacturing facilities and traffic roads are typically much higher than in regular residential areas.
• Visual observation: Pollution isn’t always visible. However, you can still assess air pollution conditions with the naked eye. If you see a thick gray or yellowish-brown haze suspended in the air, this is often a sign of poor air quality.

4. Solutions for coping with the Air pollution season

With the air pollution season approaching, proactive measures are essential to protect the health of yourself and your family.

4.1. Protective measures when being outdoor

• Monitor the AQI: Use apps like AirVisual or PAM Air to check the air quality before going outside.
• Wear specialized masks: Only use masks capable of filtering PM2.5 fine dust, such as N95, KN95, or KF94. Ordinary cloth masks are largely ineffective.
• Limit outdoor activities: Avoid outdoor exercise and work on days when the AQI is high, especially during peak traffic hours.

4.2. Protective measures at Home & in Offices

• Keep windows closed: Prevent polluted outdoor air from entering indoors.
• Use an air purifier: This is the most proactive and effective solution to create a “bubble of clean air” inside. Air purifiers equipped with HEPA H13/H14 filters can remove up to 99.97% of PM2.5 fine dust, bacteria, pollen, and more.
• Grow air-purifying plants: Some indoor plants like Snake Plants, Golden Pothos, and Aloe Vera have certain air-purifying capabilities, but their effect is supplementary.
• Clean frequently: Use a vacuum cleaner with a HEPA filter to remove fine dust that has entered the home.

Protecting your health from air pollution should start today. Be proactive in learning about and applying appropriate preventive measures to safeguard yourself and your family.

Air pollution is getting worse in urban areas, and air purifiers are an essential appliance in many households. But here’s the big question: Should you run your air purifier 24/24? And if you do, does it truly maximize performance, or could it actually backfire?

1. The Impact of Running an Air Purifier 24/24

Many people still believe that: “The more it runs, the cleaner the air!” However, the truth is that running your air purifier nonstop may not always be the best approach because:

+ The air inside your room smells odd, almost like disinfectant in a hospital.

+ The machine becomes noisier, sluggish, and far less efficient than when it was brand-new.

+ Your electricity bill slightly increased, even though the device consumes relatively little power.

+ You may notice dry, itchy skin or chapped lips, even when the weather isn’t particularly dry.

+ All these signs point to one thing: your air purifier may be overused and operating incorrectly.

2. Why You Shouldn’t Keep Your Air Purifier On All Day

2.1 Ion or Ozone Imbalance

Many modern air purifiers on the market now come equipped with ion generators or ozone technology to help eliminate bacteria and viruses. But when these machines run continuously in a closed indoor environment, the density of negative ions or ozone can become too high. Cause unpleasant odors. Lead to symptoms like nasal irritation or a tight chest, especially for sensitive individuals.

2.2 Should You Run Your Air Purifier 24/24, Filters Get Dirty Much Faster.

Running your air purifier 24/24 allows dust and pollutants to accumulate rapidly in the filters. Once the filter becomes overloaded, air can no longer pass through efficiently, meaning the purifier has to work harder to compensate.
This results in louder noise, higher energy consumption, heat build-up, and a noticeable drop in overall performance. Over time, this accelerates wear and tear on the machine and its components, shortening its lifespan and making it less cost-effective.

2.3 Indoor Air Becomes Too Dry

When an air purifier is used 24/24 in a closed room, air is constantly filtered without moisture replenishment or ventilation, leading to a drop in humidity. Which can cause: dry, irritated skin, chapped lips. For sensitive users: dry nose, sore throat, coughing, or trouble sleeping.
If possible, you should opt for models that include a humidifier or moisture-control feature, which helps balance moisture while purifying the air, such as the Puritrak Airsen AS488 air purifier.

3. If Running Your Air Purifier 24/24 Isn’t Ideal – What’s the Right Way to Use It?

To get the best results from your air purifier without causing side effects, it’s important to use it strategically and scientifically to maintain the most efficiency:

3.1 Use It in Cycles – Not Nonstop

There’s no need to keep your air purifier on all day long. Instead, run it during key periods when air pollution tends to spike, such as:
+ Early morning: During the night, fine dust particles settle quietly. As family members start moving around in the morning, those particles get stirred back into the air. That’s the perfect time to turn on the purifier.
+ Rush hour: This is when vehicle emissions are at their highest, especially if your home is near a busy road or urban area.
+ Targeted usage during indoor pollution: Switch on your air purifier when there are specific pollution sources inside your home, like: someone smoking indoors, cooking activities, pets shedding hair or dander.

3.2 Use the Right Modes for the Right Moments

Most modern air purifiers on the market today are equipped with air quality sensors. When set to Auto Mode, the purifier automatically adjusts based on real-time air quality, helping you save energy and extend the device’s lifespan.
For bedrooms or children’s rooms, Sleep Mode is a great choice. In this mode, the purifier runs at ultra-low noise levels, ensuring a peaceful night’s sleep.
Many models also come with timer settings or smartphone connectivity, allowing you to schedule when the machine turns off. This saves time, conserves power and prevents the purifier from running unnecessarily long.

3.3 Clean and Replace Filters Regularly

Running your air purifier 24/24 can speed up dust accumulation in the filters, reducing efficiency and requiring more frequent cleaning. Pre-filters: Clean every 1–2 months by removing and washing.
Activated carbon filters: Depending on how often the purifier is used and the environment, carbon filters usually need to be replaced every 12 to 24 months, but this can be flexible.
HEPA filters: The most important component in an air purifier.
On average, these should be replaced every 12 to 24 months, depending on the level of air pollution and how heavily the machine is used.
Regular cleaning and timely replacement of filters ensures your air purifier performs at its best, delivering consistently clean, healthy air for your home and family.

3.4 Monitor Air Quality via Sensor or Indicator Lights

After running your air purifier for a while, if the LED display turns green or the air quality index (AQI) returns to a safe level, that means the air is clean.
At this point, it’s a good idea to switch the machine to Auto Mode or let it automatically adjust based on indoor air quality, saving energy while maintaining performance.

4. Extra Tips to Maximize Your Air Purifier’s Performance

+ Place it in the center of the room for better airflow. Avoid placing it too close to walls, keep at least 30 cm of space, and steer clear of polluted corners.
+ Do not place it near heat sources like stoves, space heaters, or other heat-emitting appliances.
+ Pair it with indoor plants, a humidifier, or open windows regularly to maintain healthy humidity and oxygen levels in the room.

Normally, the air pollution season in Hanoi lasts from October to March of the following year. However, this year 2025, PM2.5 fine dust still “quietly stays” until April, causing the air quality to continuously be at the level of poor – bad – very bad. This seriously affects public health, especially children, the elderly, and people with underlying respiratory diseases.

1. Why is the pollution season in Hanoi unusually longer than every year?

1.1. Overloaded emission sources

– Heavy traffic, especially in the inner city with high vehicle density, often causes congestion – emitting large amounts of NOx, CO and PM2.5 ultra-fine dust.

– Non-stop urban construction: Excavation, demolition, leveling, material transportation… create large amounts of dust, especially when there are no careful covering measures.

– Spontaneous burning of straw and waste: Still common in suburban and suburban areas, especially after each harvest season.

– Industrial activities mixed in residential areas: Many small production facilities do not have a standard exhaust gas treatment system.

All of the above factors create a “cloud of pollution” that cannot escape without favorable weather conditions, causing air pollution to increase and become difficult to control.

1.2. Adverse weather

In the first months of this year, especially in April 2025, there was little rain, high humidity, and weak winds – these conditions limit the diffusion of fine dust and polluted gases, causing them to be “stuck” close to the ground, where people breathe.

– Temperature inversion (higher air temperature is lower than lower air temperature): This phenomenon prevents air from convection, and pollutants are “trapped” in the air layer near the ground.

– Climate change: Unstable weather, unseasonal rain or prolonged heat disrupt the natural purification cycle of the atmosphere.

As a result, the air is not cleaned properly as every year, causing fine dust to persist longer and the AQI index to remain high, seriously affecting health.

2. Harmful effects of air pollution on health

Dirty air does not only cause temporary discomfort. Fine dust particles, toxic gases, bacteria and volatile organic compounds (VOCs) when entering the body can lead to a series of health problems, from acute to chronic – especially serious for people with weak resistance.

2.1. Fine dust PM2.5 – “silent killer”

Ultra-small in size (≤ 2.5 micrometers), fine dust easily penetrates the body’s natural protective layers, goes deep into the lungs, and even into the blood.

– Causes chronic bronchitis, asthma, pneumonia, and even lung cancer.

– Increases the risk of cardiovascular disease, many studies show that PM2.5 is related to high blood pressure, stroke, and myocardial infarction.

– Especially dangerous for young children, the elderly, pregnant women, and inpatients.

2.2. Bacteria, viruses – pathogens in the air

In polluted environments, bacteria and viruses can easily spread and cross-infect, especially in hospitals, schools and closed spaces. This increases the risk of acute respiratory infections, influenza, and even widespread epidemics if there are no strict air control measures.

2.3. VOCs & toxic gases – slow attack

Formaldehyde, benzene, toluene… are volatile compounds emitted from furniture, detergents, wall paint… Causing symptoms such as headaches, dizziness, nausea, skin – eye – throat irritation, neurological effects and can cause cancer if exposed for a long time.

2.4. Weakened immune system – slow recovery

In polluted environments, patients after surgery or undergoing treatment often have a prolonged recovery time due to the immune system being continuously attacked. In young children and the elderly, air pollution increases the risk of acute respiratory failure and pneumonia, causing a heavy burden on the health system.

2.5. Cost Burden and Quality of Life

Air pollution increases the number of hospital stays, treatment costs, and premature deaths each year. It reduces quality of life, labor productivity, and disrupts daily activities and learning.

3. Puritrak’s air purification solutions
