Common Misconceptions About Air Quality & Ventilation


Many of us have yet to discover the benefits of air purification, and it is easy to assume it’s something we don’t need in our lives. After all, cracking open a window is enough to let fresh air in, right? Sadly, this is not the answer.


Breathing is one of the only activities we do subconsciously for the entirety of our lives, and as a result, there can be huge risks to our health if the air we breathe is dirty and of poor quality. Here at KSG, clean air is our mission, and we’re here to debunk some huge misconceptions about air quality and ventilation.

Misconception #1 - indoor air is cleaner than outdoor air


If we had a pound for every time we heard someone say ‘open the window and let some fresh air in’, we’d have won the lottery! This idea of ‘fresh air’ is misunderstood, as outdoor air can sometimes bring harmful particles with it, trapping them inside once a window or door is shut. Add this to any dust particles from indoor furniture and germs exhaled by humans if you’re in an office, for example, and all of a sudden, you're situated in a place where the air quality is far more damaging than the outdoor air. 


Sadly, cracking a window open isn’t enough to improve the cleanliness of indoor air, and in many cases, it can further decrease indoor air quality due to lingering harmful pollutants from cars, buildings and factories etc. An efficient ventilation system is essential for combatting harmful particles indoors, and if maintained properly, there won’t be a need to open a window for ‘fresh air’. 


Misconception #2 - ventilation systems will improve indoor air quality


Firstly, there is some truth to this statement, but it is not always so simple. Suppose a ventilation system is running optimally and is regularly checked and cleaned. In this case, the likelihood is that air ventilation will be efficient and will improve air quality. However, for those who install a ventilation system and do not properly maintain it, problems begin to arise.


Over time, the failure to clean the filters and maintain the ventilation system’s condition can create a clog of bacteria, dust, and harmful particles, which essentially limits the performance of such systems. Airflow can become blocked, restricting the amount of air redistributed from the system. Also, the air redistributed will be harmful if the air filters cannot do their job. 


Poorly maintained ventilation systems stop the filtering of harmful particles and create a greater risk to health by combining dirty air with bacteria, mould, and dust from inside the system, ultimately making the redistributed air more dangerous.

Given that most of us spend over 90% of our time indoors, inside is where we are most exposed to the harmful effects of air pollution, and studies around the world have shown that air quality is often worse than outside. In fact, poor indoor air quality has now been identified as one of the top five most harmful environmental risks to public health due to its connection with health issues such as heart attacks, asthma, and respiratory problems, amongst other conditions.
