Indoor Air Quality


Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures. IAQ has been neglected by most people who don’t realise it has a direct impact on their health.
The biggest IAQ misconception is that indoor air is purer than outdoor air. This is not only false, but it is also why many have overlooked and ignored their indoor air quality. While the outdoor air may be prone to synthetic and natural contaminants, the free flow of fresh air continually dilutes the air, reducing the concentration of pollutants in a given area. Indoor air, on the other hand, is plagued with pollutants from human and animal activities and the limited flow of fresh air (due to enclosed spaces) can increase the concentration of these pollutants to dangerous levels.
Due to the misconception, many have failed to ensure their IAQ is above par.

Some health effects show up shortly after a single exposure or repeated exposures to a pollutant. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person’s exposure to the source of the pollution, if it can be identified.


Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. It is advisable to improve the indoor air quality in your home even if symptoms are not noticeable.


For start a very simple way to decide whether your home may have poor indoor air quality is to look at your lifestyle and activities. Human activities can be significant sources of indoor air pollution. Finally, look for signs of problems with the ventilation indoor. Signs that can indicate the indoor area may not have enough ventilation include:

  1. Moisture condensation on windows or walls
  2. Smelly or stuffy air
  3. Dirty central heating and air cooling equipment
  4. and areas where books, shoes, or other items become mouldy

To detect odours indoor, step outside for a few minutes, and then upon reentering, note whether odours are noticeable.
