Indoor air quality is a major concern for human health and comfort. With an increasing amount of time spent indoors due to the current pandemic, this issue has become even more pressing. Air quality analysis examines various components and indicators such as airborne particles, dust levels, moisture in the air, and temperature. These components can be measured and analyzed to determine the air quality in a given environment. Poor air quality inside a building can cause a variety of health issues, such as allergic reactions, breathing difficulties, infectious diseases, and more.
Outdoor air quality can be greatly impacted by indoor environment factors like the presence of pollutants, indoor activities, as well as mechanical systems and ventilation systems. It is important to understand what is affecting the air quality of a building, since it can have a significant impact on human health. With the help of air quality analysis, data-driven solutions can be implemented to ensure the safety of any environment. Additionally, the impact of air quality on human health and comfort can be measured and monitored over time. In the next section of this article, the key takeaways from air quality analysis will be discussed in more depth.

4. Routine maintenance of the ventilation system, like changing air filters and cleaning ducts, is essential to ensuring good air quality in a building.
5. Indoor air quality can drastically impact the inhabitants; it can aggravate respiratory issues, affect mental health, and lead to problems like sick building syndrome.
What Is an Indoor Air Quality Analysis?
An indoor air quality analysis (IAQ) is an evaluation of the air quality inside a building. IAQ measurements are taken to detect the presence of chemical, biological and physical contaminants in the air. An indoor air quality analysis can help to understand the health risks and the potential long-term effects of exposure to pollutants.
What Contaminants Are Typically Tested During an Indoor Air Quality Analysis?
A variety of potential contaminants can be tested for during an indoor air quality analysis, including:
- Carbon dioxide (CO2)
- Particulate matter (PM)
- Volatile organic compounds (VOCs)
- Nitrogen oxides (NOx)
- Mold and other biological contaminants
- Lead
- Asbestos
The extent of testing and the specific types of contaminants tested for depend on the purpose of the IAQ analysis. For example, an IAQ report submitted to a building’s owner or a governmental agency may require more compliance testing than one intended to identify the source of indoor pollutant exposure.
How Is an Indoor Air Quality Analysis Performed?
An indoor air quality analysis typically involves several steps. First, an environmental consultant or other certified professional is called in to conduct an inspection of the building. This is done to identify the sources and pathways for air pollutants and understand the overall environmental conditions in the building.
The IAQ analysis itself involves taking air samples that are sent to a laboratory for detailed analysis. Sampling equipment is placed strategically around the building to measure the levels of contaminants in the air. The air samples are then analyzed to determine the concentrations of contaminants in the air. The data from the analysis is used to create a report that highlights any health risks associated with exposure to the contaminants.
When Is an Indoor Air Quality Analysis Necessary?
An indoor air quality analysis is necessary in a wide range of scenarios, including:
- Identifying the source of indoor air pollution, such as water-damaged materials, combustion appliances, asbestos or lead-based paint
- Evaluating whether a building meets environmental guidelines, such as those set by the Occupational Safety and Health Administration (OSHA)
- Determining the effect of previous environmental remediation efforts on indoor air quality
- Investigating indoor health complaints caused or exacerbated by indoor air pollutants
What Are the Benefits of Performing an Indoor Air Quality Analysis?
Performing an indoor air quality analysis offers numerous benefits. Identifying the sources and pathways of indoor air pollutant exposure can help to control potential health risks. An IAQ analysis can also help to identify mold growth or other potential health hazards that may not be immediately visible. The data collected during an IAQ analysis can also be used to inform decisions related to environmental remediation efforts.
What Are the Steps to Follow After an Indoor Air Quality Analysis?
Once an indoor air quality analysis has been completed, the following steps should be taken:
- Develop an action plan to reduce the risk of exposure to identified contaminants.
- Implement measures to reduce exposure, such as sealing off water-damaged materials or installing an air filtration system.
- Ensure that all sources for indoor pollutant exposure have been identified and controlled.
- Follow up with additional IAQ testing to evaluate the success of any measures taken to reduce exposure.
5 Tips for Improving Indoor Air Quality
- Ensure that appropriate ventilation is maintained and supply fresh air to the building.
- Have the heating, ventilation and air conditioning (HVAC) system serviced and cleaned at least once a year.
- Make sure that moisture sources such as plumbing and roof leaks are repaired and monitored.
- Clean carpets and furniture regularly and replace any water-damaged materials.
- Install an air filtration system to reduce exposure to harmful particles and other particles.
What is Indoor Air Quality Analysis?
Indoor air quality analysis is a process of testing air quality within indoor spaces. The tests are intended to identify any pollutants or hazardous substances present in order to determine the safety of the environment. This type of analysis can be conducted for a variety of spaces such as homes, workplaces, and other public spaces.
