A system that delivers measurably cleaner air to bus stops, school gates, and hospital entrances in the world's most polluted cities. Computationally validated. Deployment-ready design.
Delhi's annual PM2.5 exceeds 90 μg/m³ — 18 times the WHO guideline of 5 μg/m³
Daily bus commuters in Delhi alone exposed to roadside PM2.5 concentrations
Higher PM2.5 at roadside bus stops compared to background ambient levels
Public transit waiting areas are high-density, prolonged exposure environments. A typical 6–12 minute bus stop wait represents a disproportionate fraction of daily PM2.5 dose. School gate waiting areas and hospital entrance queues present analogous exposure profiles for children and patients with heightened respiratory vulnerability.
No cost-effective, deployable intervention currently exists at transit-stop scale.
AireOnyx draws ambient polluted air through a multi-stage treatment process, then projects cleaned air as a directed flow aimed at occupant breathing height — creating a localized zone of measurably cleaner air.
Directed airflow delivers 85% PM2.5 removal efficiency, reducing Delhi-level pollution to near WHO interim targets at the point of delivery.
Built-in sensors provide continuous air quality data, enabling performance verification and environmental reporting at every installation.
IP65 weather rated for monsoon operation. 10-minute tool-less maintenance access. Under $3K per unit at production volume.
The multi-stage treatment process provides secondary volatile organic compound reduction as an additional air quality benefit.
Full engineering validation complete — structural, thermal, and aerodynamic. Field prototype validation next.
CFD validated through OpenFOAM computational fluid dynamics simulation

Designed for Indian cities first — applicable to any high-pollution urban environment globally. Deploying through CSR partnerships, government procurement, and Air Quality as a Service (AQaaS).
“While visiting family in Delhi, the air felt like breathing poison. I watched my family and millions of commuters breathe toxic air at bus stops, outside schools, and hospitals every single day — and realized no one was building a solution that worked where they actually stood.”
