Signs Your Commercial Building has Poor Air Quality

August 15, 2024

Most Common Air Quality Issues

Several air quality issues negatively affect a commercial building, its workers, and its visitors. Here are some of the most common.

Dust Buildup

If air quality is poor, dust and other particulates can build up on surfaces. These might be outside pollutants such as vehicle exhaust or airborne dirt or soot. They also might come from indoor sources such as cleaning compounds, manufacturing chemicals, and construction materials. They can cause respiratory problems and make the facility into a place no one wants to be.

Unpleasant Odors

Obnoxious odors are a problem in and of themselves and also a symptom that larger issues might be lurking in the background. The cause could be trash and garbage not being properly disposed of. It could volatile organic compounds (VOCs) to cycle through the facility, and it could even be the result of mold or mildew.

Improper Ventilation

You can’t have safe, clean air in your building without proper ventilation. Without good movement of warmed and cooled air, the facility might feel stale and stuffy, either in a few rooms or throughout the physical plant. Poor ventilation can lead to excess humidity, which creates a breeding ground for mold, mildew, and other pathogens.

Allergens

Common allergens include dust mites, pollen, and spores. They can come from inside the building or from outdoors. These can play havoc with people who have allergies and/or asthma. The good news is that purification systems will remove almost all of these.

5 Signs of Poor Indoor Air Quality

Sometimes the signs of poor air quality are apparent inside the building itself. These symptoms include excessive humidity, dust buildup, unexplained odors, and inconsistent temperature from room to room. One of the most dramatic ways bad air quality exposes itself, however, is in the health of the workplace’s occupants. If you observe employees taking more sick days, lagging in productivity, and appearing fatigued, air quality may be unhealthy or even dangerous.


Here are five problems you might notice.

1. Coughing or Trouble Breathing

If more people than usual are coughing, rasping, or appearing to have trouble breathing, there may be airborne irritants such as dust and pollen. Breathing problems are a distraction and make it hard for employees to concentrate on their work.

2. Allergic Reactions

Telltale signs of allergic reactions include sneezing, coughing, and watering eyes. In some cases these are hard to control, People who have asthma or who are susceptible to allergies may look more uncomfortable than usual or report that their symptoms have worsened.

3. Dry Skin

Many people have dry skin as a seasonal problem, but dry skin caused by pollutants might show up at any time of year. It could be accompanied by dry eyes and eye irritation. It’s possible that an imbalance in humidity from area to area could be at fault.

4. Headaches

It’s not uncommon for people to complain of headaches when there are pollutants, particularly VOCs, in the indoor air. That’s because these irritants can cause the sinuses to inflame, increasing pressure in the head. Sometimes these headaches are accompanied by dizziness and fatigue. People who are subject to migraines are especially at risk.

5. Nausea

Some studies suggest an association between low-quality air and gastrointestinal diseases due to an altered intestinal microbiome. Nausea can be a sign that unhealthy air is moving someone in this direction.

How to Prevent Air Quality Issues

To prevent air quality issues, it’s best to eliminate the causes before they can have an impact. Routine steps like properly disposing of garbage, keeping vents open, changing filters, and using cleaning chemicals according to instructions all help. You should also watch for signs like dust buildup, odors, and excessive humidity.
