Air pollution is a serious problem that affects our health and the environment. To help people understand the level of pollution in the air, governments use the Air Quality Index (AQI). The AQI is a scale that measures air pollution and tells us how safe or unsafe the air is to breathe. 

One of the easiest ways to understand the AQI is through its colour-coded system. One of the simplest ways to interpret the AQI is through its colour-coded system. Each colour represents a specific air quality level, making it easy for everyone to assess potential health risks at a glance. In this blog, we will explore the AQI colours and their significance.

Conclusion

If the air quality is bad, try to remain indoors. Keeping track of AQI reports in your area helps ensure the well-being of you and your family.

Along with monitoring the AQI, regular medical checkups are vital for early detection and long-term health management.
