What we have measured, and how
Spot readings by our team, each with its date, site and photo. Independent monitoring under a written protocol is part of every pilot proposal.
Pureva
Romit Resins Pvt Ltd, July 2024
First Pureva adsorber, on the flue of a resin plant in Pali, Maharashtra. Handheld flue-gas analyser at inlet and outlet.
Spot reading, as displayed on the instrument. Not O₂-corrected.
SuVayu-Bake
Wood-fired pizza oven, 14 May 2026
First unit, on a wood-fired oven. Handheld meter at the exhaust: unit bypassed, then unit in line, six minutes apart.
One spot reading by our team. The next installations are measured under a written before/after protocol.

Protocol
How we run a pilot
The protocol written into every pilot proposal. One report for the host, the regulator and the sponsor.
Baseline
Unit off for the first days. Record normal pollution and peak periods at all measurement points.
Controlled on/off
Alternate operation under matched wind and traffic conditions. Measure at the intake, the discharge and at 1.5 m breathing height.
Continuous run
Assess stability, energy, noise and maintenance over the full period, typically 30 to 90 days.
Independent review
Third-party analysis of the dataset and a written scale-up recommendation against pre-agreed pass criteria.
Host or sponsor a pilot
Sites are being selected for SuVayu 10K, SuVayu 2K and the next Pureva installations. Hosts and sponsors get the full dataset and the independent report.
