Dyson Introduces the Latest Dyson Pure Cool Purifying Fan in Singapore

If you are thinking of investing in a purifier and a fan, you need to know a little about what you are getting. In Dyson latest product, the Dyson Pure Cool Purifying Fan, it is clearly an engineering feat to ensure that both the fan and purifier perform at their best and still looking nice in this clean and minimalist design.

I have personally see these products in action and am convinced that they are engineering feat. Of course, the demos might be done in controlled environment. Do check out the detailed press release and have a go yourself (if you happened to see their demo in malls).

Here are some other information on what pollution you will get in your home.

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 and potentially throughout their life.

Dyson launches new purifying fans to clean every corner of the room1

Dyson’s unique approach to purification driven by in-house expertise in electronics, filtration, and airflow.

  • Dyson Pure Cool™ purifying fans reveal the indoor pollution you can’t see – new LCD display reports pollutants in the home in real time, and then react automatically using a unique Dyson algorithm.
  • Dyson’s Pure Cool TM purifying fans feature a 360 degree fully-sealed filter system combining an activated carbon filter to remove gases, and a Glass HEPA filter that captures 99.95% of microscopic allergens and pollutants as small as 0.1 microns 2.
  • Air Multiplier™ technology and new 350⁰ oscillation project and mix purified air around the whole room to purify every corner. Fan mode and diffused mode deliver year round usage 3.

[Singapore – 12th April 2018] Today Dyson released the new Dyson Pure Cool™ purifying fans, which bring together Dyson’s expertise in airflow, filtration and electronics to tackle the issue of indoor air pollution and purify every corner of the room 1.

Most of the air we consume is indoors where we spend 90% of our lives 4, but it can contain microscopic particles which are invisible to the human eye. Pollution sources like urban pollution, particulate matter and pollen can enter the home and combine with indoor pollution sources like cleaning products, pet dander and disintegrated faeces, scented candles, indoor paints and cooking fumes. Because modern homes are becoming better sealed to comply with energy efficiency requirements, pollutants can be trapped inside and circulation of airflow can become compromised.

The new Dyson Pure Cool™ purifying fans – in a large tower format for floor placement, and a small desk format for worktops and floors – automatically purify the whole room properly*, capturing gases and 99.95% of ultrafine particles as small as 0.1 microns 2.

Paul Dawson, Vice President for Dyson Health and Beauty, said: “At Dyson we develop machines for real people and real homes, creating technology that works well in the test lab but more importantly doing what they’re expected to do in a real-world setting. To clean the air at home, a purifier needs more than a filter. It needs to automatically sense pollution, capture gases and ultrafine particles, and project clean air to every corner of the room. The Dyson Pure Cool™ purifying fan does all of this, making it the only purifier fan to clean a whole room properly*.”

*AHAM AC1-2015 standard sets out how air cleaner manufacturers can define their performance by “the relative reduction of particulate matter suspended in the air in a specified test chamber”. This means their performance is based on cleaning efficiency rates only. We design our purifying fans to go beyond test chamber conditions and focus on real home conditions – this is more than just having an efficient filter. When Dyson engineers set out to design a purifying fan, their research concluded that to clean an entire room properly, you also need to sense pollution events automatically; capture ultrafine pollutants; and project cleaner air around the room using Air Multiplier™ technology. Only the Dyson purifying fan is designed and tested to do all of this 5.

Sensing: A new LCD display shows which particles and gases the Dyson Pure Cool™ purifying fan is automatically sensing in real time. A unique Dyson algorithm processes the input from three sensors and then displays air quality readings.

Lasers measure and detect ultrafine particles. A separate sensor detects the amount of VOCs (Volatile Organic Compounds, such as benzene and formaldehyde, emitted from paint, burning candles and materials in furniture) and NO2 present. A third sensor measures relative humidity and temperature.

Capturing: An improved filter in the new Dyson Pure Cool™ purifying fan captures both particulate matter and gases. Dyson engineers have incorporated 60% more HEPA media into a taller and deeper filter, and they’ve introduced three times more activated carbon, which can absorb gases, odours, domestic fumes and VOCs.

Nine metres of condensed and sealed borosilicate microfiber filters capture 99.95% of particle pollution as small as 0.1microns2, including allergens, bacteria, pollen and mould. Activated carbon filters, which have been coated with Tris (Trishydroxymethylaminomethane) to increase the absorption efficiency, remove gases including NO2, formaldehyde and benzene.

Dyson filters meet the industry standards of EN1822 and H13-A filter class.

Projecting: The Dyson Pure Cool™ purifying fan is the only purifier with Air Multiplier™ technology and 350⁰ degree oscillation, allowing it to project clean air to every corner of the room. By expanding the degree of oscillation to 350⁰ degrees and using Air Multiplier™ technology, the machine can project 290 litres of purified air per second to every corner of the room 6.

To avoid a cooling effect in winter, the Dyson Pure Cool™ purifying fan features a unique new diffused airflow mode. Along with the forward airflow mode, which cools you as a fan with purified air, there is now a diffused airflow or purification-only mode, which can be used when you want to purify the air but don’t want cool air blowing on you.

Inside the annular loop a valve mechanism is driven by a brushless stepper motor, to allow switching between diffused mode and fan mode.

Fan mode

In fan mode a baffle stays in place to deliver a powerful, frontward stream of purified air. This can cool you down in the summer while purifying the room.

Diffused mode

The baffle moves to block the front aperture, diverting air through the rear of the annular loop at a 45⁰ angle. Because the aperture is wider, this creates a more diffused airflow, uses less energy and generates less noise. And purification effectiveness is maintained, without the cooling airflow.

Dyson Link app: Available for iOS and Android, the Dyson Link app enables you to track indoor and outdoor pollution, temperature and humidity levels. You can also use it to control your machine and see how many hours of filter life you have left.

The new machines come with full Over the Air Update Capability (OTA) – meaning Dyson owners can continue to get the most advanced Dyson software even after purchasing the machine 7.

Engineered for real homes: Dyson purifying fans are designed to work in real homes. Some manufacturers of conventional air purifiers gauge their performance using a laboratory test method called ‘Clean Air Delivery Rate’. It is conducted in a compact chamber just 12m2 in size, with an added fan to circulate the air – and only one sensor to measure air quality. It is not representative of the average living room environment.

Dyson engineers created a lab test called the POLAR test. It is based on a larger living room size, with no added fan. Eight sensors in the corners of the room and one sensor in the centre collect air quality data every 5 seconds, detecting particles of indoor air pollution that are 300 times narrower than a human hair. Analysing the data across all nine sensors lets Dyson engineers ensure the Dyson Pure Cool™ purifying fans deliver a uniform cleaning performance throughout the whole room 5.

Evan Stevens Head of Engineering for Dyson Environmental Control said: “We needed to test our machines in an environment that reflects how our owners actually use their machines and the rooms in which they are used. So we built a chamber without a ceiling fan, made it 27m2 in size, and added 9 sensors capable of detecting particles 300 times narrower than a human hair. 3D mapping our machine’s performance in this chamber lets us know that when our machine says the air in a room is clean, it truly is clean”.
