Act two · The scale

Where today lands

From a crisp horizon to smoke you can taste — here’s your reading on it.

9.9 µg/m³
CrispSome smokeHeavy smoke

Act three · The ladder

What each rung feels like

  • 0–3µg/m³Natural air. About as clean as outdoor air realistically gets.
  • 3–5µg/m³Exceptionally clean. Crisp, destination-worthy air.
  • 5–9µg/m³Good, not pristine. Clean city air; most people will not notice anything today.
  • 9–15µg/m³Elevated. Usually no big deal today; sensitive lungs may notice hard exercise.
  • 15–35µg/m³Polluted. Smoke or traffic pollution is now worth acting on.
  • 35–55µg/m³Unhealthy for sensitive. Symptoms become more likely, especially with asthma or heart disease.
  • 55+µg/m³Unhealthy. Everyone should reduce exposure and clean the indoor air.

Act four · The fine print

The receipts

What is PM2.5?

Fine particles about 30× thinner than a human hair — small enough to slip through your lungs and into your bloodstream. We measure them inµg/m³: micrograms of particle mass in a cubic metre of air.

The math

PM2.5 here is 9.9 µg/m³.Berkeley Earth: 22 µg/m³ for 24 h ≈ 1 cigarette.A week at this level: 9.9/22 × 7 = 3.1 cigarettes.A long-term health-risk equivalence, not literal smoking.See how we work it out →
