New arrival: Dyson Pure Cool purifying fan in Singapore

The latest version of Dyson’s Pure Cool purifying fan adds an LCD display, a new filter and 350⁰ degree oscillation. Prices below.

The new Dyson Pure Cool purifying fan comes in Desktop version (S$699, White/Silver) and Tower version (S$899, White/Silver, Black/Nickel, Iron/Blue).

In the new Pure Cool purifying fan, Dyson leverages its in-house expertise in electronics, filtration and airflow to clean every corner of the room.

The new LCD display reports pollutants in the home in real time, and then reacts automatically using a Dyson algorithm.

The purifying fan features 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.

Air Multiplier technology and new 350⁰ oscillation project and mix purified air around the whole room to purify every corner.

A new diffused mode offers users from temperate countries the option, in winter, of purifying the air without the cooling effects of the fan.

More details below from the press release.

Most of the air we consume is indoors where we spend 90% of our lives, but it can contain microscopic particles which are invisible to the human eye.

“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,” said Paul Dawson, Vice President for Dyson Health and Beauty.

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.


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.


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 0.1microns, including allergens, bacteria, pollen and mould.

Activated carbon filters, which have been coated with Tris compound 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.


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.

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 and Diffused modea

In fan mode a baffle stays in place to deliver a powerful, frontward stream of purified air.

“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,” said Evan Stevens Head of Engineering for Dyson Environmental Control.

This can cool you down in the summer while purifying the room.

In 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.
