How the impact is estimated
Impact (0–100) for each organ = 100 × (1 − e−dose/H). The dose blends the average PM2.5 above the WHO guideline (5 µg/m³), scaled by how long the exposure lasted, with peak-day pollution (90th percentile above 15 µg/m³), then multiplies by an age-sensitivity factor for that organ. Eyes, nose and throat react mostly to short spikes; brain, heart, kidneys, pancreas and liver to long-term exposure.
Organ sensitivities are modelled on published PM2.5 findings (lung, cardiovascular, stroke/dementia, kidney and diabetes studies; WHO 2021 guidelines). The cumulative view adds the build-up from years of exposure.
How protection is modelled
On days with PM2.5 of 60 µg/m³ or more, your exposure is recalculated as time outdoors (about 1.5–2.5 h/day, depending on age) × (1 − N95 benefit) plus time indoors × 60% of outdoor PM2.5 reaching a typical Delhi home × (1 − purifier benefit).
A well-fitted N95 is credited with 70% less inhaled PM2.5 (50% for children under 12, none under 2); a correctly sized HEPA purifier in regular use with 60% less indoor PM2.5. Real-world results vary with fit, filter condition and how consistently you use them.
About the data
Daily PM2.5 (24-hour average) from the U.S. Department of State monitor at the U.S. Embassy, Chanakyapuri, New Delhi, published through AirNow, covering 1 Nov 2021 – 5 Nov 2026. Days with no reading are skipped, not estimated.
AQI is calculated from PM2.5 alone using the US EPA (2024) or India CPCB breakpoints, so official CPCB bulletins (which also use PM10, NO₂, O₃ etc.) can be higher on some days. One monitor cannot represent every Delhi neighbourhood.
