Real-time air pollution data you can act on

We work with construction companies and the surrounding communities to monitor air pollution both at source and in nearby homes, schools and places of work.

With real-time data from a network of monitors, site workers can take instant remedial action (like slowing down or damping down) to avoid exceeding air pollution limits - before it enters nearby communities or triggers site shut-downs.

And with devices placed in nearby buildings, the community can see what's in the air they're breathing in the places that matter most to them.

We identify the activities that cause spikes in PM2.5

Knowledge is power

By constantly sampling PM1, PM2.5, PM10, VOCs and CO2, our devices provide a swarm of data from multiple locations (you can place and move them as often as you like) to give a detailed picture of the causes of air pollution and how it spreads.

Knowing in detail which activities create the most air pollution is key to reducing your impact and demonstrating your committment to clean air to your clients, local authorities and other stake-holders.

As well as monitoring the external air pollution from industry, our devices know about in-building air pollution (which is around five times worse than outside air pollution) and we will offer simple, practical advice to help people to improve the quality of the air they breathe by improving ventilation and using less polluting cooking techniques.

How CompAir
devices work

Working with the world-famous University College London, we’ve developed a small, portable air pollution monitor which uses precision laser-optical technology to examine the air.
We call this an Airtracker.   

The Airtracker detects key airborne pollutants including particulate matter (PM1, PM2.5 and PM10) which is emitted from engines, factories and other sources of combustion, CO2 and harmful Volatile Organic Compounds (VOCs) .

This information is sent via 3G/4G to our cloud storage which you can access via our app or dashboard.


Clever technology – simple output, including an internationally recognised Air Quality Index score.

Construction in Progress

A partnership for cleaner air

Our approach gives our partners in the construction industry the chance to engage with and reassure the communities they serve.

We help you to win bids, strengthen relationships and  reduce costly delays.
