Do you need an air quality monitor?

You’re not the only one concerned about breathing polluted air.

In fact, approximately 3.8 million individuals pass away each year due to indoor air pollution issues.

Particulate matter is the main culprit that causes various respiratory illnesses, including not limited to impaired lung function, asthma, cancer, and respiratory inflammation.

Bad air quality also lowers productivity and the ability to grasp information, that’s why air quality monitors are essential pieces of equipment in the workplace.

Common Contaminants

VOCs (Volatile organic compounds)

Organic chemicals that are released from processes and products. For example, disinfectants, dehumidifiers, cleaning agents, and more.

CO (Carbon monoxide)

Cannot be seen, smelt, or tasted and could result in symptoms like chest pain, impaired vision, and fatigue.

CO gases are emitted from generators, car exhausts, boilers that are poorly maintained, and more.

PM (Particulate matter)

This is typically a combination of liquid drops and solid particles hanging in the air, like smoke, dust, soot, or pollen.

The PM’s that are the most worrisome are the ones that are the tiniest as they could lead to lung and heart issues when inhaled.

Outdoor PM is created through construction. For example, fossil fuels that enter a building. Indoor PM is created by cigarette smoke, fireplaces, and the like.

Other pollutants for sensor measuring include:

• Methane
• Radon
• Nitrogen dioxide
• Carbon dioxide

Normal Air Condition

Humidity and temperature are vital components for testing air quality. When the levels are too high it can cause several other issues.

Indoor temperatures can be more problematic to manage than you think. This is because of factors like outdoor conditions, heat escalations from sunlight, and the ventilation rate of the air outside.

Recommended temperatures for normal air conditions range from 68.5°F  to 75°F during winter and 75°F  up to 80.5°F in summer.

The relative indoor humidity level must be managed at 65% or lower. To prevent mold growth, a humidity level between 30% and 60% must be maintained.

How To Test

Indoor air quality monitors are equipped with sensors that detect some of the input in your physical surroundings, for instance, motion, temperature, and light.

It sends that data to a signal that is measured and communicated digitally.

An indoor air quality monitor detects any signs of specific pollutants. There are various types of sensors used to detect different pollutants or gases.

Indoor sensors are placed strategically in various areas of your home or building to generate accurate results. Here are the sensor placements for specific pollutant detection:

• Detection of chlorine levels – Floor
• Detection of ozone and carbon dioxide levels – Breathing height (middle)
• Detection of carbon monoxide, methane, nitric oxide, or ammonia levels – Ceiling height

Improving Air Quality

The reason behind monitoring the air quality indoors is to create a healthy environment because the air we breathe has a direct influence on our health. To improve air quality:

• There must be sufficient ventilation (clean air must be introduced and distributed).
• Pollutants/contaminants must be managed.
• The humidity levels and temperature must be comfortable.
