Making the invisible


Currently 99% of us are breathing toxic air. It's an invisible killer causing 4.9 million premature deaths a year through strokes, heart disease, lung cancer and respiratory diseases.

The problem is harder to tackle because most air pollution (particluate matter and VOCs) is invisible even at dangerous levels.

Out of sight, out of mind.

But not with CompAir. Our devices offer detailed daily and monthly visual reports, helping industries to reduce pollution at source - avoiding harmful emission and costly site shut-downs.

The importance of visibility 

In Britain the 1956 Clean Air Act was the result of a public outcry at visible air pollution known as smog.

But because the tiny particulates and gases which make up modern forms of air pollution are so small, we can't see them.
That was our first challenge. How to make the invisible, visible.

The smallest (PM2.5) particles our device can see are just 2.5 micrometres (2.5 millionths of a metre) in diameter.
These particles are the most dangerous - so small that, like viruses, they pass through our lungs and into our blood.
