As air quality in the national capital continues to deteriorate with the latest Air Quality Index (AQI) sitting at between 400 and 500, i.e. ‘severe’, we take a look at some of the cleanest states in the country.
As of 11-14-2025 01:05:00 PM (local time), the Northeastern state is reporting an AQI of 98, and the air quality is “moderate.”

What makes the air in these states cleaner than the rest?
The northeastern and Himalayan states of Arunachal Pradesh, Sikkim, Meghalaya, Mizoram, Tripura and Himachal Pradesh record consistently cleaner air compared to most urban centers in India. Many geographic and environmental factors contribute to an improved Air Quality Index (AQI).

According to Dr. Manas Mingar, Consultant Pulmonologist at Thane Kims Hospitals, “Some areas are still blessed with clean air because nature still has a strong influence there. Dense forests have become huge air purifiers, absorbing pollutants and releasing clean oxygen. Mountains ensure there is natural airflow and, hence, there is little settling of pollutants. Low population density translates into fewer vehicles, minimal construction, and relatively little industrial activity. With slow urban growth and abundant greenery, the air remains Lighter, cleaner, and much less harmful. Daily life in such places exposes the lungs to fewer irritants than in crowded and congested subways.
What determines air quality?
According to the central pollution Control Panel (CPCB), an AQI between 0 and 50 is considered “good”, 51-100 “satisfactory”, 101-200 “moderate”, 201-300 “poor”, 301-400 “very poor”, and 401-500 “severe”. With Delhi remaining in the latter category, these cleaner states remind us that sustainable living, low emissions, and environmental conservation can ensure clean air – a luxury for millions in India’s urban centres.
Here’s how breathing polluted air affects your lungs
Dr. Mingar explained, “Inhaling polluted air forces the lungs to work harder every day. Small particles from traffic fumes, burning waste, dust, and industrial smoke irritate the airways, making breathing less efficient. Many people notice symptoms such as coughing, chest tightness, shortness of breath, and burning eyes when pollution levels rise.”
He added that smaller particles are the most harmful because they travel deep into the lungs and can enter the bloodstream. This affects heart function, increases inflammation, and weakens overall immunity. “Children and the elderly tend to experience these effects sooner, but even healthy individuals can develop decreased tolerance, recurrent throat infections, and respiratory problems in the long term if exposure continues.”

The doctor advises that some simple habits can make daily breathing easier during peak pollution. Here’s what you need to do:
– Wear a good N95 mask when going outdoors.
– When smog is usually at its worst, avoid outdoor activities in the early morning and late evening.
– Keep doors and windows closed on days when pollution is high.
– Use an air purifier at home, especially where you sleep.
– Drink plenty of water to help the body get rid of toxins.
– Wash your face and rinse your eyes after you return home.
– Add antioxidant-rich foods such as oranges, nuts, green leafy vegetables, and herbal teas to your routine.
– Move drills indoors when air quality decreases.
– Track the Air Quality Index (AQI) before planning travel.
– Keep indoor plants that support clean air, such as snake plants and peace lilies.
