3 Common Factors That Impact Indoor Air Quality

You may have heard the statement that indoor air can be around 5 times more polluted than outdoor air. Since so much emphasis is being paid on prevention and control of outdoor air pollution, indoor air quality issues are seriously neglected.
In this article, we’ll take a look at some common factors affecting air quality inside your homes and commercial spaces that many of you may not be aware of.

Humidity Levels

It goes without saying that temperature and indoor air quality go hand in hand. Humidity levels are found to play an important role in the quality of indoor air. High humidity can lead to the growth of mold, which is harmful for your health.
Moreover, it’s worth noting that indoor temperature is harder to control due to external factors like heat gains from sunlight, outdoor air ventilation rate, as well as outdoor condition that are beyond your control.

Contaminants

So many pollutants that affect indoor air get released from sources inside a building while some are also drawn in from the outside. Some of the most common contaminants include:

Volatile Organic Compounds

VOCs happen to be one of the main contributors to poor indoor air quality. These are essentially organic chemicals that are emitted in the form of gases from different products and processes. Common sources of VOCs involve disinfectants, dehumidifiers, and cleaning agents.
VOC contamination from outdoors includes chemicals that exist in polluted groundwater that gets pulled inside indoor spaces during water consumption.

Particulate Matter

Particulate matter is also found both inside and outside. It’s a mixture of liquid droplets and solid particles in the air like pollen, smoke, dust, and soot and it can be produced by smoking, fireplaces, and other such activities. These particles can be inhaled and can have a harmful effect on your heart and lungs.
Outdoor particulate matter, on the other hand, gets generated during construction or due to the burning of fossil fuels and can easily enter into buildings through ventilation.

Carbon Monoxide
