Dyson’s new fans can keep you cool and also purify the air

Dyson has just launched a new range of purifying fans which can not only keep you cool but also rid of your home of potentially harmful pollutants and allergens at the same time.

The Dyson Pure Cool fans combine several of the company’s key technologies in airflow and filtration to tackle indoor air pollution.

This pollution comes from a number of sources including cleaning products, scented candles, indoor paints and cooking fumes.

And the design of our modern homes, which are sealed to comply with energy efficiency requirements, are making matters worse because these pollutants are trapped inside.

“Poor air quality can affect our day-to-day productivity so it’s extremely important to understand what’s in the air we breathe whether you’re at home or at work,” Professor John Bell,Head of Science and Engineering at Queensland University of Technology.

A recent Dyson survey showed 66 per cent of respondents, or someone in their household, suffered from allergies.

“Airborne allergens live in the air we breathe, gathered from dust mites, pollen, pet hair and mould,” said clinical allergist and a regular authority with the National Asthma Council Australia, Dr Sheryl van Nunen.

“They are so small you would never be able to see them with the naked eye, but they can have a huge effect on our short term and long-term health.

“This is why it is so important to prevent and eliminate airborne allergens the best way we can, including using an air purifier.”

The new Dyson Pure Cool purifying fans are available in a floor or desktop model and can capture gases and rid the air of 99.95 per cent of fine particles as small as 0.1 microns.

The fans draw in the polluted air and then project clean air to every corner of the room using the company’s patented Air Multiplier technology.

There is now a new LCD display on the fans that show exactly what particles and gases the unit is sensing in real before they are purified.

Under the hood lasers measure and detect ultrafine particles and a separate sensor detects the amount of VOCs (volatile organic compounds) which are emitted from paints, candles and furniture while a third sensor measures temperature and relative humidity.

The onboard HEPA filter now has three times more activated carbon to absorb gases, odours, domestic fumes and VOCs.

The Dyson Pure Cool purifying fans can now oscillate 350 degrees to project 290 litres of purified air per second to every corner of the room.

There is also a new diffused airflow mode that can still purify the air and cool the room without blowing air on you.

Users can also control the fan through the Dyson Link app (available for iOS and Android) and also track the indoor pollution and outdoor air quality along with temperature and humidity levels.

The Dyson Pure Cool purifying fans are available in two versions – a larger tower for floor placement and a smaller model for desks and worktops.

Both are available in White/Silver and Black/Nickel and are priced at $649 (desk format) and $799 (floor format).

Pollution sources at home

  • Outdoor air pollution: Sources such as tree pollen, particulate matter and city pollution can enter the home and may remain trapped there.
  • Wood burning fireplaces and stoves:Wood-burning fireplaces and stoves emit particulate matter during combustion.
  • Pollen: Plants and flowers can release microscopic pollen into the air.
  • Pet hair and disintegrated faeces: Cats, dogs and other household pets can spread this microscopic material around the home.
  • Scented candles: Some chemical substances found in scented candles can release benzene and formaldehyde into the air as they burn.
  • Furniture foam: Foam that can be found in furniture can release formaldehyde gas
  • Indoor paints: Some indoor paints can use volatile organic compounds, which can be released as gaseous chemicals when they dry and potentially throughout their life
  • Air fresheners: Some household air fresheners can contain volatile organic compounds and benzene, which can be released with the fragrance when sprayed.
  • Gas hobs and cooking fumes:Gas hobs and the food cooking process itself can emit fumes, odours and particles into the air.
  • Cleaning products:Household cleaning products can contain benzene and household fumes and odours.
  • Carpets, rugs and flooring:Some carpets, rugs, flooring and their backing materials can emit formaldehyde when new
