Why is air quality important?

Do you know what you’re breathing? With Elm, you do.

You see “air pollution,” but Elm sees discrete particles, toxins, and other irritants that can be monitored and understood. That’s why Elm monitors for all these and more:

  1. VOC

    Volatile Organic Compounds

    From naturally occurring methane to highly toxic chlorofluorocarbons, VOC can profoundly affect air quality — both inside and outside the home.

  2. O3


    Coughing, throat irritation, inflammation of the airways, and increased asthma attacks can be attributed to exposure to ground-level O3.

  3. PM


    Fine particles – especially those sized PM2.5 or below – can lodge deep in the lungs and contribute to serious health concerns, especially for those with lung or heart disease.

  4. NO2

    Nitrogen Dioxide

    Cars, power stations, even butane stoves, produce NO2 – and though easily detectable, it can bring on severe respiratory impairment after long exposure.

  5. NO

    Nitric Oxide

    Easily converted to nitric acid and nitrogen dioxide, NO is thought to be a key cause of acid rain, and together with NO2 contributes to ground level ozone formation and scavenging.

  6. dB


    Not officially considered “air pollution,” noise pollution can produce adverse health effects, too: increased stress, high blood pressure, hearing loss, sleep disruption – and lost productivity.

  7. H


    Humidity is the amount of water vapor in the air. Humidity indicates the likelihood of precipitation, dew, or fog.
