What Is Air Quality Index (AQI)?
The Air Quality Index (AQI) is a measurement system used to show how polluted the air is.
It helps people understand whether the air is safe to breathe or not.
AQI values are shown as numbers.
Lower AQI means clean and healthy air.
Higher AQI means polluted and harmful air.
In India, AQI ranges from 0 to 500.
Each range shows a different health impact.
Children, elderly people, and asthma patients are affected first.
Breathing poor-quality air daily causes serious problems.
It affects lungs, heart, sleep quality, and immunity.
That is why indoor air quality improvement is extremely important today.

Why Indoor Air Quality Is a Serious Concern
Many people believe outdoor pollution is the only danger.
This is not true.
Indoor air can be 2 to 5 times more polluted than outdoor air.
Pollutants get trapped inside homes.
Ventilation is often poor in modern houses.
Common indoor pollutants include dust, smoke, pet hair, mold, and chemicals.
Cooking fumes and mosquito repellents make it worse.
Bad indoor air quality causes fatigue.
It increases allergies and headaches.
Long-term exposure leads to respiratory diseases.
