With the bushfire crisis in NSW creating weeks of poor air quality across the state, more and more families are looking into investing in an air purifier for their households.

Sydney's Air Quality Index (AQI) measured at a concerning 154 today, with the pollutants entering our lungs being compared to the health risks associated with pack-a-day smokers.

So, what can you do in the face of these seemingly uncontrollable conditions?

Bushfires on the NSW Mid North Coast have caused health authorities to issue an air pollution warning across the city as conditions deteriorate. Light northerly winds will do little to help the air quality, with the city smothered by the smoke . Smoke haze settles in Sydney Harbour.

People love to drink purified water, but the thought of purifying the air you breathe barely rates a mention. The average adult inhales 11,000 litres a day, given the ongoing bushfire conditions it may well be worth looking at an air purifier.

Dyson offers an extensive range of sophisticated purifiers that are exceptionally effective. These devices can detect ultrafine particles, such as Volatile Organic Compounds, (VOC's), Nitrogen Dioxide (NO2) and Particulate Matter (PM). Via HEPA filters, the products capture 99.95 per cent of anything harmful and release fresh air back into your home.

Many of them are smart connected too, so you can see real-time data about conditions inside your home. So sensitive are these machines, a spray of deodorant in another room can set them off.

TruSens

There are more affordable options. The brand TruSens offers three purifiers to suit room sizes. The TruSens range differs from Dyson's offerings in that it doesn't act as a fan or even a heater. It blows air upwards after it has been sucked in and processed by what the brand calls DuPont Air Filtration and Ultraviolet Sterilisation.

The system draws in air from a 360-degree angle at the base then removes microscopic particles, allergens, volatile organic components and odorous gases. Then to further add insult to injury to these nasties, it uses an Ultraviolet Sterilisation light to kill germs and viruses that may build up in the filter.

The other major difference is that the on-board air quality sensors are not on board at all. It uses a remote device called a SensorPod Air Quality Monitor.

Why staying indoors to escape bushfire smoke in big cities is a waste of time - as expert calls for government to build clean-air refuges for Aussies with breathing problems

  Why staying indoors to escape bushfire smoke in big cities is a waste of time - as expert calls for government to build clean-air refuges for Aussies with breathing problems A respiratory expert has called for fresh-air refuges where people can escape severe air pollution as Australia's east coast suffers through a second month of smoke haze.

A second active carbon filter removes gases, smoke and odours. Finally, a High-Efficiency Particulate Air (HEPA) filter removes the stuff you can't see, such as allergens, dust and dust mites.

If you are really into stats it can scrub out particles as small as 0.003um or 99.97 per cent of all the nasties in the air.

Air is sucked in via two side vents and ejected from the top of the product. Hence, it's important to keep in mind that it won't act like a fan, as the Dyson version does.

Pictures: Cities with the dirtiest air in the world

a view of a city: With problems of climate change being exacerbated in the past 10 to 15 years, our air quality is at risk more than ever before. Some of the adverse effects of poor air quality can be as severe as stroke, lung cancer, and chronic pulmonary disease, or even premature death. Unfortunately, there are many cities around the globe—most of which are concentrated in the Middle East and India—where air quality is so poor that it is extremely unhealthy. The top three countries with the most polluted cities are India with 11, Bahrain with four, and Pakistan with three.  The World Health Organization (WHO) monitors this air quality closely and ranks cities based on ambient (outdoor) air quality, based on two measures. The first is mean particulate matter between 2.5 and 10 micrometers in the air, known as coarse air quality (PM10), and the second is mean particulate matter less than 2.5 micrometers in the air, known as fine air quality (PM2.5). Both metrics are measured in micrograms per cubic meter of air (ug/m3).  In order to compile the following list, Stacker took data from WHO's 2018 list and measured each of the top 25 cities with the worst air quality for PM10 and PM2.5. In the case of a tie in terms of PM10, the tie was broken by the city with the higher annual mean PM2.5 amount.  Read on to find out which cities have the dirtiest air in the world and which have increased, even incrementally, the quality of their ambient air in the past few years.
