21 Dec, 2025
Summary
- AQI in Mumbai's Juhu Beach area recorded at 191-200.
- N95 mask placed on air quality monitor caused AQI to plummet.
- Delhi's air pollution worsened, with some areas in severe category.
A striking experiment conducted by a Mumbai resident has captured attention regarding air pollution levels in India. The individual placed an N95 mask over the air inlet of an air quality monitor located at Juhu Beach. Initially reading between 191 and 200, the AQI rapidly decreased to 37 once the mask covered the sensor, demonstrating a significant reduction in perceived pollution.
Upon removing the mask, the AQI surged back to 201, further emphasizing the mask's immediate effect in the demonstration. This viral video has sparked discussions on social media about the necessity of masks and lifestyle changes for combating smog. Many users shared personal experiences of improved breathing by wearing masks in polluted environments.
This incident unfolds as other major Indian cities grapple with deteriorating air quality. Delhi, in particular, experienced a sharp increase in pollution, with several areas reaching the 'severe' category. This contrasts with Mumbai's situation, though the experiment underscores the widespread concerns over air quality across the nation.
