18–21 minutes to read

Ensuring high indoor air quality in commercial and public spaces is crucial for the well-being, health, and comfort of occupants and visitors. According to the Environmental Protection Agency, Americans typically spend around 90% of their time indoors, including prolonged periods at work.

The EPA notes that indoor air can often contain more pollutants than outdoor air. Consequently, subpar indoor air quality can lead to significant health issues. The resulting loss in productivity and increased sick days can lead to national revenue losses amounting to tens of billions of dollars each year.

What causes poor indoor air quality?

Indoor air quality can be diminished by a range of pollutants and chemicals originating from both outside and inside the building. Building occupants may be exposed to these harmful elements for long and frequent durations. The EPA cites the following:

• Chemical pollutants from sources like tobacco smoke, cleaning products, gases expelled by building materials and furnishings can irritate the nose, throat, lungs, and cause headaches.
