A Mumbai man’s Instagram experiment showed AQI dropping from ‘poor’ to ‘good’ when an N95 mask covered a monitor.

In a video shared on Instagram, user Aneesh Bhasin used a portable air quality monitor at Juhu Beach to record real-time air quality. The device initially showed an Air Quality Index (AQI) reading between 191 and 192, placing the air in the ‘poor’ category.
Bhasin then covered the air inlet at the back of the monitor with an N95 mask. Within seconds, the AQI reading dropped sharply and stabilised at 37 – a level considered ‘good’. When the mask was removed, the AQI spiked again, rising to around 201.

Social media reactions
The video, captioned “N95 masks do work,” quickly gained traction on social media, garnering over 2.1 million views and sparking a wave of reactions. While some express concern over the pollution levels and implications for public health, others responded with humour and scepticism.
“As a Respiratory Medicine resident, I wish I could play this video on a loop in my OPD. The difference between 192 and 37 is exactly what saves your lungs from long-term damage!” one user commented.
“i can second this! i had v severe dry eyes whenever i returned home after going out, and i only recently got an N95, and it is SO AMAZING, the eyes dont get dry as they used to, like genuinely a 90% reduction in dryness, please get one folks, 40 rupees per mask every few weeks wouldn’t hurt!” said another.
“This is right influencing! Mask is a must until this pollution settles!” wrote a third user.
“I won’t be surprised if the Delhi government decides to cover AQI monitors across the city with giant N95 masks instead of spraying water,” one user joked.
