Indoor Air Quality in Offices: The Risk You Can’t See
Poor indoor air quality can affect employee wellbeing, comfort, and productivity long before obvious signs appear. This article explores the common causes of IAQ issues in office environments and why proactive assessment is essential for maintaining a healthy, compliant workplace.

Article overview
Office environments are often assumed to be low risk. Clean, controlled, well-maintained.
But indoor air quality (IAQ) doesn’t always behave the way we expect it to.
In fact, some of the most persistent issues we investigate come from spaces that look perfectly fine.
Why IAQ Gets Overlooked
Unlike dust or fumes in industrial settings, IAQ issues are less obvious.
There’s no visible warning sign in most cases. Instead, they show up gradually through:
Headaches
Fatigue
Poor concentration
General discomfort
Which makes them easy to dismiss or misattribute.

From what we see in practice, IAQ issues often come down to a few key factors:
Inadequate ventilation
Poor maintenance of HVAC systems
Build-up of indoor pollutants
Changes in occupancy or layout
Even small changes can have a noticeable impact over time.
This matter because there’s a tendency to treat IAQ as a comfort issue rather than a compliance one.
But that’s shifting.
Employers still have a responsibility to provide a working environment that doesn’t pose a risk to health, and air quality plays a big role in that.
IAQ assessments and testing helps answer a simple question:
Is the environment actually suitable for the people using it?
It removes the guesswork and gives you something tangible to act on. In many cases, the fixes are relatively straightforward once the issue is properly understood.
Most offices are fine. But the ones that aren’t rarely realise it until it’s been affecting people for a while. That’s why it’s worth checking; just to be sure.
