Noida AQI — Live
The number above is Noida’s current US-EPA AQI, calculated from the nearest sector station via IQAir (GPS-based lookup, since the city-name endpoint is unreliable for Noida). Below the live number: what it means right now, the threshold reference, and what actually works to protect indoor air.
What this AQI value means right now
| AQI | Category | What it means for your day |
|---|---|---|
| 0–50 | Good | Open windows. Outdoor exercise fine. Rare in Noida. |
| 51–100 | Satisfactory | Sensitive groups (kids, elderly, asthma) should limit prolonged outdoor exertion. |
| 101–150 | Moderate | Unhealthy for sensitive groups. Limit outdoor time for kids; close windows. |
| 151–200 | Poor | Unhealthy for everyone. Run any indoor air filtration you have. |
| 201–300 | Very Poor | Reduce outdoor exposure. Mask outdoors. Indoor PM2.5 likely elevated unless you have active filtration. |
| 301+ | Severe | Stay indoors with active filtration. WHO 24-hour PM2.5 guideline of 15 µg/m³ is being exceeded 20×+. |
The WHO recommends PM2.5 below 15 µg/m³ averaged over 24 hours. Noida’s annual average sits around 80–110 µg/m³ — 5× to 7× the guideline.
Why Noida air is the way it is
Noida is part of the wider Delhi NCR airshed, with localised contributors:
- Industrial belt — Noida and Greater Noida have substantial industrial activity, particularly along the Yamuna Expressway corridor
- Vehicle emissions — heavy commute traffic on the DND, NH-24, Yamuna Expressway; high diesel-cab density
- Construction dust — ongoing residential and commercial development across newer sectors (62, 75, 78, 137, 150)
- Yamuna floodplain dust — particulate matter from the riverbed and adjacent open fields
- Stubble burning (Oct–Nov) — northwesterly winds bring Punjab/Haryana smoke; Noida sits in the same airshed as Delhi
- Power plant proximity — Dadri thermal power plant ~30 km east contributes to PM2.5 background
Monsoon brings limited relief — PM10 washes out, PM2.5 largely persists.
Indoor air in Noida apartments — the data parents miss
Most Noida residents live in towers (Sector 75, 78, 137, 150 etc.) with sealed glass façades and central HVAC that does not bring in fresh air. Indoor PM2.5 tracks outdoor PM2.5 with a 1–2 hour lag. CO₂ in closed bedrooms overnight reaches 1,500–2,500 ppm — well above the 1,000 ppm WHO comfort threshold.
Air purifiers help with PM2.5 (in the room they’re in) but cannot reduce CO₂. Whole-home positive-pressure ventilation handles both: pulls outdoor air through H13 HEPA, pushes it in continuously, pressurises the home so polluted air leaks out.
What aqi0 does
We install positive-pressure fresh air systems for Indian homes. Indoor PM2.5 stays below 10 µg/m³ with fresh filters. CO₂ flushes continuously below 1,000 ppm. One unit covers up to 2,000 sq ft (a typical 2–4 BHK).
| Item | All-in (incl. 18% GST) |

| Fresh Air System (installed) | ₹70,000 + GST (₹82,600 all-in) |
| Annual AMC | ₹12,500 + GST (₹14,750/year all-in) |
Bundle perk: the aqi0 AQI monitor (₹6,000) is included free when AMC is signed on the same invoice as the system.

Frequently asked questions about Noida AQI
What is Noida’s AQI today?
The live number at the top of this page is Noida’s current air quality index, calculated from real-time PM2.5 readings via IQAir. It refreshes hourly. Noida shares the NCR airshed with Delhi and Gurugram, so its AQI tracks Delhi’s closely — annual average around 180–210, winter peaks regularly above 350.
Is Noida’s AQI worse than Delhi’s?
Slightly better on most days but not by enough to matter. Noida sits east of Delhi in the same airshed, with the Yamuna acting as a partial buffer for some pollution sources. Winter inversions and stubble-burning smoke affect Noida nearly as much as Delhi. The practical answer is the same: indoor air needs active filtration year-round.
Why does Noida’s AQI spike in winter?
Three combined causes. (1) Stubble-burning smoke from Punjab and Haryana paddy residue (peaks Oct–Nov). (2) Cold-layer inversions trap pollution near the ground — wind speed drops, vertical mixing collapses, and pollutants accumulate over days. (3) Local sources persist year-round: vehicle traffic on the Noida-Greater Noida Expressway, NH-24, and DND Flyway, plus construction dust across Sectors 75, 78, 100, 137, 150.
What’s a safe AQI for kids in Noida?
The WHO 24-hour PM2.5 guideline is 15 µg/m³, equivalent to AQI under 50. Children’s developing respiratory and cognitive systems are particularly sensitive to PM2.5 exposure. Noida outdoor air rarely meets this guideline outside of monsoon. Indoor PM2.5 below 10 µg/m³ — achievable with active fresh-air filtration — is the practical target for households with young children.
How can I keep Noida indoor air clean?
A positive-pressure fresh air system is the single solution that addresses both PM2.5 and CO₂ for the whole home year-round. It pulls outdoor air through H13 HEPA filtration and pumps it indoors, pressurising the home so pollution leaks out rather than in. Air purifiers reduce PM2.5 in one room but cannot reduce CO₂ from breathing. Sealing windows alone helps briefly. Noida installs are opening in 2026 — site surveys are booking now.
What Noida could look like
DLF Mall of India sharp on the horizon, light rail, families on picnics, AQI 18 instead of 318. aqi0 is the indoor half of that future, working today.
