How transit air purifiers work
Public transport vehicles operate in dense urban corridors where PM2.5 concentrations routinely exceed safe limits. Passengers, drivers and staff spend extended periods in enclosed cabins that recirculate polluted air drawn from street level.
Our ceiling-mount transit purifiers draw cabin air through a staged filtration train — a washable pre-filter for coarse dust, followed by HEPA-grade media and an optional UV-C sterilization stage. The compact form factor is designed specifically for vehicle ceiling cavities.
Each unit operates at low noise levels appropriate for passenger comfort, with automatic fan-speed modulation based on occupancy and air-quality sensor readings. Units are designed for the vibration, temperature and duty-cycle demands of daily transit operations.

Tested in Real Transit Conditions
Our bus air purification systems have been tested in live operating conditions on Indian city buses — measuring PM2.5 reduction, cabin air quality improvement, and system performance under real-world duty cycles. Field trials include monitoring with certified IAQ-SC air quality sensors to verify filtration performance during actual service routes.
