How Does Air Conditioning Improve Air Quality?
Air conditioning doesn’t just exist to keep you cool during the hot summer—it also helps improve air quality in your home. The combination of open windows and your aircon unit creates a healthy air quality balance.
Keep reading below to learn more about pollutants and how you can improve your air quality.
How Does Air Conditioning Improve Air Quality in Your Home?
Your air conditioning unit doesn’t actually do much to support healthy indoor airflow, and the benefits largely depend on the model you buy. For example, a more efficient unit will collect dust particles and trap bacteria. But then what happens?
It’s a common misconception outdoor air is brought into your property, including new bacteria, by your aircon unit. But it’s actually the same air already inside your property that is used—essentially recycled.
Without regular maintenance, such as cleaning the air conditioner or replacing the filter, the leftover particles are continuously spread throughout the room. While it does slightly improve air quality and lower humidity, opening your windows and doors further protects your home, overall reducing condensation.
What Affects Indoor Air Quality?
The main pollutants affecting indoor air quality are:
– Dust
– Chemicals
– Cleaning products
– High humidity levels
– Carbon dioxide (CO2)
– Smoke (cooking, candles, tobacco, etc)
– Art and DIY materials (paint, glue, felt tips, etc)
– Condensation consequences (mould, damp, mildew, etc)
How Can Air Quality Be Improved?
Condensation is a major starting point of bringing harmful bacteria into your home. Your indoor air quality is largely influenced by the bacteria already in your property. When you leave, you remove bacteria, which is spread elsewhere. When you re-enter, more bacteria is brought into your property.
While your aircon unit traps some of these particles, it doesn’t provide efficient-enough ventilation properties other than producing cold or warm air. Because of this, the humidity isn’t low enough to stop or remove condensation from your windows, which causes mould and damp.
In turn, this produces even more bacteria that is spread throughout your property. To truly improve air quality in your home, we recommend turning on your air conditioning and opening your windows simultaneously in the morning to quickly banish condensation.
