Delhi Pollution: Delhi has spent much of November under a blanket of smog. GRAP Stage III restrictions were invoked on November 6, when the daily average AQI stood at 382. The city recorded a Diwali-day reading of 376, its highest since 2021, and a season high of 391 on November 9, with several stations crossing 400. Commuters, children and people with respiratory conditions are bearing the brunt.

What Is the Atovio Pebble?
The Atovio Pebble is a lightweight wearable air purifier worn on a neck lanyard like a pendant. It is filterless, charges via USB Type-C and is priced at ₹3,499. Instead of filtering air, it releases negative ions (anions) that attach to particles such as PM2.5, so they clump together and drop out of the breathing space. The brand says it creates a personal clean-air zone around the face.
What Testing Shows
According to the brand and a Zee News review, the Pebble was evaluated at IIT Kanpur’s National Aerosol Facility. It achieved over 99.9 per cent reduction in PM2.5 and PM1 particles in a sealed controlled lab test. The brand has also cited testing at Kitasato Research Center in Japan.
The Limits To Keep In Mind
Lab results do not automatically translate to real-world performance. The Pebble works best in still-air settings such as offices, cars or indoor spaces. Moving traffic, wind and crowded open areas are harder conditions. One review notes the review had to put the lab result in context. The device is also not a medical product. For severe AQI days, a well-fitted N95 or N99 mask is still the safer baseline.
Is It Worth Considering?
For commuters and office workers who want an extra layer of protection, the Pebble is an affordable, low-maintenance option with no filter costs. It is best treated as a supplement to masks, indoor purifiers and limiting outdoor exposure. Anyone with asthma or a heart or lung condition should consult a doctor.
