Problem: NOx and VOCs

Dangerous air pollutants

We all need to breathe. But much of the air we inhale contains nitrogen oxides (NOx) and volatile organic compounds (VOCs) — pollutants that can cause everything from asthma to cancer. And that’s a problem: indoors, locally and regionally.

Regional Air Quality

On hot, sunny days, local air pollution can turn into an even larger problem, when the NOx and VOCs from cars and smokestacks undergoes a series of chemical reactions that generate smog.

The result can blanket the entire region, leading to thousands of premature deaths, overloading emergency rooms and making it dangerous to exercise outdoors.

Local Air Quality

The World Health Organization has declared outdoor air pollution a public health emergency, responsible for 4.2 million deaths in 2016.

Industry and traffic are a big part of the problem, generating NOx, VOCs, particulates, sulphur dioxide and more. And people living or working near major roads, highways or industrial emitters suffer the greatest health consequences.

Indoor Air Quality

Typical North Americans spend more than 90 per cent of their time inside buildings, where the air quality is often worse than outdoors.

Traffic and industrial pollution can sneak inside through doors, windows and HVAC systems. Meanwhile, paints, carpets and construction materials give off VOCs, including formaldehyde.
