Did you know that indoor air pollution can have a significant impact on your health?

In fact, indoor health pollution has been linked to many different harmful health effects. According to numerous studies it is estimated that human beings are exposed to two to five times more pollutants indoors when compared to their outdoor exposure. Even more concerning is the fact that in some cases the exposure levels were more than 100 times greater!

Obviously, indoor pollutant exposure should be a major concern. When you consider the fact that people today spend the majority of their time indoors, it should make the is issue an even bigger concern. Given the importance of indoor air quality (IAQ), properly managing it and ensuring that we are all breathing healthy air can be accomplished by taking the following measures:

  • Control pollutants – Start by controlling airborne pollutants in your home.
  • Fresh air throughout your home – Ensure that fresh, outdoor air is distributed throughout your home.
  • Temperature and humidity levels – Keep temperature and humidity at acceptable levels.
  • Service regularly – Making sure your heating and cooling appliances are serviced regularly and free from any mould, grime and debris that could be affecting the quality of air.


When it comes to maintaining healthy indoor air quality one area that is often overlooked is temperature and humidity. In many homes, the temperature and humidity levels are controlled by your air conditioning or gas heating systems. It is vital to keep this equipment serviced and maintained on a regular basis to ensure that the air which circulates within your home is clean and pollutant-free. The truth is that temperature and humidity are two of the most important factors that influence the air quality in your home.

When looking at indoor air quality you also need to look at outdoor air quality. Why is that? Simple, outdoor air enters your home through doorways, windows, ventilation, etc. So, if you have outdoor air that is unhealthy entering your home, it’s going to fill your home with pollutants. This means that transportation and maintenance activities also influence indoor air pollutant levels.


Why Indoor Air Quality (IAQ) is so important in today’s world

Did you know that indoor air pollution is considered to be one of the top five environmental risks to public health? Believe it or not, this is true and is backed up by numerous studies performed by the EPA and the Science Advisory Board. Indoor air is a vital part of keeping an indoor environment healthy, which means that homeowners, schools, and various other facilities should make keeping indoor air quality a priority.

To summarise, failing to make healthy indoor air quality a priority can lead to the following:

  • Long and short-term health problems
  • Cough
  • Eye irritation
  • Skin Rashes
  • Allergic reactions
  • Life-threatening conditions
  • Carbon monoxide poisoning

On top of these health concerns, poor indoor air quality can also aggravate asthma symptoms and other respiratory disorders. When you consider the fact that nearly 1 out of every 13 children suffers from a breathing disorder, the importance of healthy indoor air cannot be overstated. Children exposed to poor indoor air quality can experience the following:

  • Impact student attendance in school as well as their comfort and performance
  • Decrease productivity and staff performance
  • Accelerate the deterioration and reduce the efficiency of any institution
  • Create negative publicity
  • Create liability issues
  • Strain relationships
  • Increase potential for institution closings or relocation of occupants

What symptoms should you be on the lookout for that could indicate that there is a problem with the air quality in your home?

  • Headaches
  • Fatigue
  • Shortness of breath
  • Sinus congestion
  • Coughing
  • Sneezing
  • Dizziness
  • Nausea

Healthy indoor air is critical for good health

Many Australians spend a lot of time indoors. Whether it’s at home, in the office, or other buildings, there are pollutants just about everywhere you look. The pollutants can cause eye irritation, headaches, fatigue, and allergies. These pollutants are often cycled in the air by unmaintained air conditioning systems.

More serious types of indoor pollutants can cause much more severe types of long-term complications, including cancer. Some examples of indoor air pollutants include the following:

  • Radon is a gas that is extremely dangerous, in fact, it’s the second leading cause of lung cancer right after smoking. It can enter homes through cracks and other openings.
  • Second-Hand Smoke. Second-Hand smoke is an incredibly dangerous indoor air pollutant that is especially concerning for people with asthma. In addition to aggravating respiratory conditions, increasing the risk of cancer, and increasing the risks of getting ear infections, it also raised the chances for Sudden Infant Death Syndrome.
  • Combustible Pollutants. Combustible pollutants come from fuel sources that produce carbon monoxide and nitrogen dioxide. These are introduced to a home through improperly vented appliances such as wood-burning stoves, gas stoves, dryers, and fireplaces.

Regardless of where you live, there is a good chance that you spend a significant amount of time indoors, which means you have little chance of being exposed to exchange air. Studies have shown that the average person spends as much as 90% of their time indoors, with about 65% of that spent in their homes.

When you realize that the air in your home is between 7 and 10 times as polluted as the air outside, the importance of improving the air quality simply cannot be overlooked. But, what can you do about it? Something that is in your control is making sure your heating and cooling equipment is not adding to the concerns of poor air quality in your home. By having your heater or an air conditioner serviced regularly you will be sure to prevent any airborne diseases from being spread throughout your home and affecting you and your family!
