Overview
- Instagram user Aneesh Bhasin recorded a portable monitor at Juhu Beach falling from about 191–192 to 37 when the air inlet was covered with an N95 mask, then jumping back to around 201 after removal.
- The clip spread widely on social media, with reported view counts ranging from roughly 41,000 to more than 2 million.
- Multiple outlets noted they have not independently verified the video or confirmed the accuracy of the demonstration.
- Pulmonologists told the Indian Express that an N95 can filter particles before they reach a sensor or a person’s lungs but does not change the surrounding air.
- The video renewed discussion of mask use during periods of poor air quality in India, drawing praise from some medical voices and skepticism from other users.
