Is ‘fresh air’ as fresh as you think?

May 11, 2022

With air quality a major concern to public health thanks to increasing air pollution, it is crucial now more than ever to consider the air quality surrounding you, indoors and out.

It may sound strange, but ‘fresh air’ might not be as fresh as you think. In fact, opening a window when a room feels stuffy or taking a break outside could do more harm than good, depending on the outdoor air quality in your area. 

The issue with poor air quality

Of course, the quality of air is dependent on a number of variables, but there will most likely always be some form of air pollution outside, so it’s important to understand why opening a window for ‘fresh air’ does not necessarily do the job.

The World Health Organisation (WHO), estimate that 92% of the world’s population live in areas where air pollution exceeds safety limits, so chances are the areas in which you live and work don’t have air as clean as you think it is.

Poor air quality has the potential to harm everybody’s health, especially in buildings where there are vulnerable people. Hospitals and care homes are full of patients who are unwell and breathing in dirty air is highly likely to contribute to a deterioration in their health. Opening windows is often deemed adequate to improve air flow and air quality, however, thanks to poor outdoor air quality this is not always a solution. 

What’s not clean about ‘fresh’ air?

Most of us are aware of the pollutants that contaminate the air, such as toxicants from factories, vehicles, burning of fuels, etc. However, the quality of the air we breathe and the effect on our health is often overlooked.

Studies have shown that long term exposure to polluted air can cause health issues such as heart attacks, asthma, and respiratory problems and with air pollution ever-worsening, we all need to pay more attention to the dangers of poor air quality.

Scientists have reported that indoor air quality is sometimes two to five times worse than outdoor air, thanks to airborne chemicals which linger and are hard to remove, especially if you are in an old building where the ventilation is weak. However, if you work in a city office with vehicles running past all day then there’s a high chance that opening a window will do more harm than good as you will be introducing more dirty air. 

So, what can be done? Seal buildings off from outdoor air or have all the office windows open all the time? Sadly, the answer isn’t that simple - but it could be Genano.

How Genano can eradicate the issue of poor air quality

Genano air purifiers are the only devices that clean air down to a nanometre scale, breaking down the smallest of particles that the air carries. Perfect for buildings like schools, hospitals, and houses, the purifier can clean large volumes of dirty air before redistributing cleaner air several times an hour to large areas. 

Genano devices use a powerful electronic filtration system, removing particles as small as mould toxins of 0.000001mm size and larger particles such as viruses, air pollution, bacteria, and pollen. As the air is redistributed, it passes through a carbon plate which removes compounds and smells from the air. 

With public health and air quality more important than ever, the need for quality ventilation within buildings is critical.

There's only one way of knowing air is of clean quality, and that's through our Genano technology® - which can decontaminate air from particles to nanosize. At KSG Health, we prioritise making air is as clean as possible, which will ultimately help benefit people’s health wherever they may be.
