Mission Zero Emission
Clean air, where the pollution actually is.
Patented adsorbent systems that capture particulate matter and toxic gases at the source: in factory stacks, at traffic hotspots, inside hospitals, above ovens and on your air conditioner.
Concept render One chemistry, five applications
The same adsorbent, built into the form each place needs
Bhagirath’s powder binds sulphur and nitrogen oxides, carbon oxides and volatile organics. We package it with the right filtration and airflow for each environment, from a 25,000 CFM tower to an add-on for a split AC.
Pilot unit in fabrication SuVayu 25K
A compact, modular tower that pulls 25,000 CFM of polluted air at a traffic junction or bus terminal, strips particulates and toxic gases, and returns cleaner air at breathing height.

Design stage SuVayu 2K
A 2,000 CFM unit that sits inline with an existing air-handling system and adds particulate, gas and microbial treatment without depending on HEPA filters.

Pilot installed · May 2026 SuVayu-Bake
A compact unit that captures soot, ash and smoke from wood-fired pizza ovens, bakeries and tandoors, so small outlets can meet city rules without civil work.

Home pilots · 2026 Airova
An add-on that fits an existing split AC and uses its airflow to remove fine dust and odours from the whole room, with no extra floor space.

Installed · Romit Resins, 2024 Pureva
A dual-chamber adsorption tower, filled with Bhagirath’s patented powder, that captures SOx, NOx, CO and CO₂ from boiler and furnace exhaust without water, effluent or high voltage.

Numbers with a date, a place and an instrument
We publish what we have measured and say how we measured it. Every figure below is a spot measurement with a handheld analyser; standardised protocols with independent monitoring are part of every pilot we propose.
How it works
Capture the particles. Bind the gases. Measure the result.
Staged particulate capture
Pre-filters and fine filters take out dust, soot and PM2.5 without a HEPA dependency.
Dry adsorption
Air passes over trays or beds of Bhagirath’s patented powder. Acid gases and carbon oxides bind to it; nothing is washed into water.
Safe media cycle
Spent powder is removed on schedule and disposed of on land or used in cement products. Two-chamber units alternate so treatment never stops.
Monitoring and reporting
Inlet, outlet and breathing-zone readings, time-stamped, so operators, regulators and sponsors see the same numbers.
Who we work with
Built for the people who have to fix the air, not just report it

Learn more →From the founder
“Existing pollution-control methods are costly and inefficient, and clean fuels alone are not enough. We spent thirty years in analytical chemistry learning what flue gas is made of. Bhagirath exists to take it out of the air at a price a small plant or a city can actually pay.”
Our principle
We measure before we claim
Every deployment starts with a baseline. We alternate on and off periods under matched conditions, measure at the intake, the discharge and at breathing height, and ask for independent analysis before anything is scaled. Concept visualisations on this site are labelled as such; photographs are of real installations.
- Baseline first, then controlled on/off comparison
- Breathing-zone measurement points, not only stack readings
- Independent analysis before scale-up decisions
- No area-wide AQI promises
