Viral Wearable Air Purifier Tested: What Science & Doctors Really Say

If you live in Delhi or North India, you’ve probably seen the viral wearable air-purifier ad everywhere. But does it actually work? We break down the science behind this device, which releases negatively charged ions to push particles out of your breathing zone—without truly filtering the air. The company shared three research papers, but most tests were done indoors, where this product wouldn’t realistically be used. Outdoor results showed around 40% reduction in pollution, but doctors say evidence is weak for typical urban air. Experts emphasize that for fine particulate matter, an N95 mask is still far superior. This gadget is not a replacement for proper masks or HEPA purifiers—only a minor extra layer, at best.
