Indoor air quality

Measure. Understand. Improve.

  • 61%

    better cognitive performance

    Cognitive scores were found to be higher in good vs. bad indoor air quality settings.

  • 48%

    lower disease transmission

    U.S. schools with improved ventilation and air filtration had lower incidence of COVID-19.

  • 3 Mio

    potential life savings

    Indoor air pollution is associated with three million premature deaths annually.

  • Several billion dollars

    in federal funds can be used to improve indoor air quality

  • 90'000 CO₂ sensors

    were installed in classrooms across Quebec

  • Belgium's "ventilation plan"

    CO₂ meters need to be placed in every public room.

  • 300'000 CO₂ monitors

    have been purchased by schools so far

  • Classrooms

    are equipped with air purifiers including CO₂ monitoring

  • Investing 500m euros

    in improving ventilation systems

Common indoor air pollutants: sources and health impacts

Contaminated aerosols

Exhaled aerosols can contain infectious virus particles and stay airborne for an extended period. Several diseases (e.g. COVID-19, Influenza) are known to transmit via aerosols (airborne transmission).

Particulate matter (PM2.5)

Particulate matter agitates preexisting conditions, irritates lungs, and can cause heart attacks and cancer

Carbon dioxide (CO2)

Carbon dioxide impacts overall cognitive performance, sleep quality and causes drowsiness

Mold

Molds produce microscopic airborne allergens or chemicals. Growth of mold is prevented by keeping the relative humidity below 70%

Volatile organic compounds (VOC)

Airborne chemicals that result in temporary and chronic health conditions such as irritations and lung cancer

Formaldehyde

Specific VOC that causes eye irritation and can cause cancer at elevated concentrations

Nitrogen oxides (NOx)

Nitrogen oxides damage the human respiratory system at elevated concentrations
