What is the Actual AQI of Delhi-NCR?

Air pollution in Delhi-NCR is a growing problem that worsens every year, especially in the winter months. But when you check the AQI (Air Quality Index) to understand how bad it is, you may notice different apps and websites showing completely different numbers. Some report AQI between 300 to 500, while others claim it is as high as 900 to 1900. So, what is the actual AQI of Delhi NCR, and why is there so much confusion?


Why Do Different Apps Show Different AQI?

If you’ve ever been confused by AQI readings, you’re not alone. Here’s why different platforms show varying numbers:

  1. Different Calculations: Each app calculates AQI based on different factors, such as PM2.5, PM10, or gases like nitrogen dioxide. This variation leads to different results.
  2. Location Variations: The AQI near highways or industrial areas is much higher than in residential zones. Apps may focus on specific locations, creating the discrepancy.
  3. No Standard Authority: With no single source controlling the data, different readings add to the confusion.

What is the Real Cause Behind Pollution?

To better understand why Delhi-NCR faces such a crisis, let’s look at the main contributors:

  • Stubble Burning: Every winter, farmers in nearby states burn crop residue, releasing harmful pollutants into the air.
  • Vehicle Emissions: The sheer number of vehicles in Delhi-NCR releases toxic gases, worsening the air quality.
  • Construction Dust: Ongoing construction across the city releases dust and other particles into the atmosphere.
  • Firecrackers During Diwali: Despite bans, firecrackers during festivals lead to sudden AQI spikes.
  • Smog Formation: Fog combines with pollutants to form thick smog, reducing visibility and air quality.
  • Geography: The northern mountain ranges block airflow, trapping polluted air over Delhi-NCR.

Why Can’t Administrative Bodies Control Pollution?

It’s frustrating to see the pollution problem returning every year. Unfortunately, several factors make it difficult for authorities to control this issue:

  • Seasonal Challenges: Pollution levels rise dramatically during winter, making it hard to respond in time.
  • Weak Implementation: Although there are rules and regulations, enforcement is often lacking.
  • Limited Long-Term Planning: Solutions like cleaner fuel, better waste management, and public transport improvements are not implemented effectively.

How Pollution is Affecting People

Pollution impacts everyone, but some groups face more severe consequences.

  • Newborns and Kids: Their lungs are still developing, making them highly vulnerable to respiratory diseases.
  • Pregnant Women: Air pollution can lead to complications during pregnancy.
  • Senior Citizens: Those with existing health conditions, such as asthma or heart problems, are at greater risk.

Tips to Protect Yourself from Bad AQI

Living in Delhi-NCR during the winter months can feel overwhelming, but there are steps you can take to stay safe:

  1. Use Air Purifiers: Keep your home air clean with good-quality air purifiers.
  2. Wear Protective Masks: N95 and N99 masks can help filter out harmful particles.
  3. Avoid Outdoor Activities: Stay indoors, especially during peak pollution hours in the morning and evening.
  4. Boost Your Immunity: Eat a diet rich in antioxidants, including fruits, vegetables, and nuts.

What is the Future of Air Quality in Delhi-NCR?

The worsening AQI in Delhi-NCR raises a critical question: What kind of environment are we preparing for future generations? If we continue down this path, our children will face even more severe health risks. Immediate action is needed to tackle pollution and improve the AQI for everyone.


What Can We Do as Individuals?

While authorities play a big role in solving this issue, we can also make small changes:

  • Reduce vehicle use by carpooling or using public transport.
  • Avoid burning waste or using firecrackers.
  • Advocate for stricter environmental policies.

Together, we can make a difference and improve the air quality in Delhi-NCR for ourselves and the generations to come.


The pollution crisis in Delhi-NCR is not just an environmental issue—it’s a public health emergency. Knowing what is the actual AQI of Delhi NCR and understanding its causes are the first steps toward tackling this problem. By working together and taking proactive measures, we can create a healthier future for everyone.
