Can wearable air purifiers protect Delhi residents from pollution?

No, experts caution that wearable air purifiers are merely a cosmetic accessory and cannot match the high level of protection offered by certified N95 masks, particularly in heavily polluted outdoor environments.

How effective are wearable air purifiers in reducing pollutants?

Wearable air purifiers are mainly effective in reducing airborne particles within the "personal breathing space" under enclosed or low-ventilation indoor conditions. Their effectiveness diminishes rapidly in highly turbulent or open outdoor settings.

What are the limitations of wearable air purifiers in Delhi?

Wearable air purifiers are not a solution to Delhi's pollution crisis, as they only provide limited personal protection and cannot address the root cause of the city's air quality issues.

Wearable Air Purifiers: Delhi's Pollution Savior or Mere Accessory?

As of November 17th, 2025, Delhi's air quality index (AQI) continues to hover between the 'Severe' and 'Very Poor' categories, posing serious health risks to residents. In response, many are turning to wearable air purifiers as a quick fix, though their effectiveness remains questionable.

According to the Central Pollution Control Board (CPCB), an AQI between 301-400 is classified as 'very poor', while 401-500 falls into the 'severe' category. Prolonged exposure to such poor air quality can cause respiratory illness, particularly among those with lung and heart disease. At severe levels, even healthy individuals may experience respiratory impacts.
