What are the key steps Delhi residents can take to protect themselves from air pollution?

According to the article, Delhi residents should monitor AQI daily, use well-fitting N95/FFP2 respirators on high-pollution days, run HEPA air purifiers in their homes, and reduce indoor pollution sources like tobacco and unvented cooking.

How effective are air purifiers in improving indoor air quality in Delhi?

The article states that high-efficiency particulate (HEPA) air cleaners can markedly lower indoor PM2.5 levels when sized and run correctly, and that randomized studies have shown substantial reductions in indoor particle levels and some downstream health benefits.

What is the impact of long-term exposure to PM2.5 on Delhi residents' health?

The article explains that long-term exposure to PM2.5 increases chronic risks like cardiovascular disease, COPD, and stroke, and that the damage accumulates over time without producing immunity, so reducing exposure benefits everyone at all ages.

Debunking the Myths: Clearing the Air on Delhi's Pollution Crisis

Summary

Indoor air often reflects outdoor pollution, requiring risk-reduction measures
N95/FFP2 respirators offer better protection than cloth or surgical masks
Air purifiers can substantially lower indoor PM2.5 levels when used correctly

As Delhi-NCR faces its annual air pollution crisis, a web of myths continues to spread on social media and in public discourse. However, public health experts have now stepped in to debunk 10 persistent misconceptions around air quality and its impact on health.

One of the key myths is the belief that staying indoors offers complete protection from outdoor pollution. In reality, PM2.5 particles often infiltrate homes through windows, doors, and ventilation, leaving indoor air quality highly reflective of outdoor conditions. Authorities emphasize the need for additional risk-reduction measures, such as using high-efficiency particulate air (HEPA) cleaners, alongside staying indoors.

Another common myth is the assumption that cloth or surgical masks provide the same level of protection as N95/FFP2 respirators. In fact, well-fitting N95/FFP2 masks substantially reduce personal exposure to fine particulate matter, while the efficacy of other masks varies widely.
