What is Assessed During an Indoor Air Quality Indicator Assessment?

Indoor air quality plays a significant role in our overall well-being and health. If the air quality in your home is poor, it can cause allergies, asthma, and respiratory issues. To ensure that your indoor air is clean and healthy, an Indoor Air Quality Indicator Assessment is conducted. This assessment measures various indicators, including carbon dioxide, carbon monoxide, relative humidity, and temperature. In this blog post, we will discuss what is assessed during an IAQ Indicator Assessment and why it is important for your overall well-being.

Carbon Dioxide (CO2) Levels

One of the crucial parameters assessed during an indoor air quality indicator assessment is the carbon dioxide levels. High levels of CO2 can lead to fatigue, dizziness, and poor concentration. Professionals use carbon dioxide sensors to measure CO2 levels and determine if they are within acceptable limits.

Carbon Monoxide (CO) Levels

Carbon monoxide is a colorless and odorless gas that is toxic to humans. It can be emitted from faulty heating systems, stoves, or poorly ventilated combustion appliances. During an assessment, professionals check for carbon monoxide levels using specialized sensors to ensure the safety of occupants.

Relative Humidity

Maintaining appropriate humidity levels in indoor spaces is crucial for comfort and health. High humidity can cause mold growth and respiratory issues, while low humidity can lead to dry skin and static electricity. Professionals use humidity meters to measure relative humidity and recommend actions to maintain a balanced level.


Temperature plays a vital role in the overall comfort of indoor spaces. Extreme temperatures can negatively affect productivity, sleep quality, and overall well-being. During an assessment, professionals assess the temperature using thermometers and recommend adjustments to ensure a comfortable environment.

Particulate Matter and Allergens

Indoor spaces can be contaminated with particulate matter, such as dust, pollen, pet dander, and other allergens. These particles can trigger allergies and respiratory issues, especially in individuals with sensitivity. Professionals use air sampling techniques and particle counters to measure the presence of particulate matter and allergens.

Volatile Organic Compounds (VOCs)

Volatile organic compounds are emitted from various sources, such as cleaning products, paints, furniture, and carpets. These compounds can have both short-term and long-term health effects. Indoor air quality assessments often include monitoring for VOCs using specialized equipment to determine if levels are within acceptable limits.

Ventilation Efficiency

Proper ventilation is crucial in maintaining good indoor air quality. During an assessment, professionals evaluate the efficiency of ventilation systems, ensuring that fresh air is properly circulated while minimizing the presence of pollutants.

Indoor air quality plays a significant role in your health and well-being. By addressing these factors, you can ensure a safe, healthy, and comfortable environment for yourself and your loved ones.
