A toxic gas found in varying degrees in the air, high levels of nitrogen dioxide (NO2) can negatively impact human health. Airsset offers a system that includes NO2 air quality monitors, so you can track nitrogen dioxide levels in your air – in real-time.

Why is it important to monitor nitrogen dioxide levels?

Too much NO2 can lead to decreased lung function, as well as irritation in the eyes, nose, throat, and respiratory tract. And that’s just in low levels. Prolonged exposure of higher amounts of NO2 can lead to the development of acute or chronic bronchitis.

NO2 is used in industry settings as a catalyst, oxidizer, and more. It’s also emitted as a by-product during processes like waste treatment, heating a building, and certain construction practices that involve diesel fuel, all of which can push nitrogen dioxide right into your system’s air intake. Whether you’re a landlord or a business owner, this means that your space could have unhealthy levels of NO2.

Nitrogen dioxide can accumulate due to un-vented heaters, improper use of exhaust fans, and underserviced central heating systems. Business owners with warehouses or large workspaces should also be aware of how certain industry practices can impact their building’s NO2 levels.

Without a system that includes a NO2 air quality monitor, your occupants may be exposed to unhealthy levels of nitrogen dioxide that could lead to serious health issues.

Low levels of NO2

Can cause an increased risk of respiratory infections, and health issues for those with asthma and chronic diseases.

Continued exposure to nitrogen dioxide

In high doses can lead to acute or chronic bronchitis.
