Wearable air purifiers: Doctors and Science weigh in on viral gadget

This report investigates the effectiveness of popular wearable air purifiers, examining the negative ion technology they claim pushes pollutants from the breathing zone. The analysis reviews company-provided research, including a test by IIT Kanpur, and features expert opinions from Dr. Anurag Agarwal, Dean of Biosciences and Health Research at Ashoka University, and Dr. Vivek Nangia from Max Hospital. Dr. Anurag Agarwal states, 'this device works better for larger particles like incense smoke, but the evidence is much weaker for typical urban pollution'. The bulletin concludes that these devices are not a substitute for N95 masks or HEPA filters and, at best, offer a supplementary layer of protection, urging viewers to trust science over social media advertising.
