Dyson has introduced the Dyson Pure Cool purifying fans, which leverage the company’s expertise in airflow, filtration, and electronics to address indoor air pollution and purify entire rooms.

Dyson first entered the purifying fan market in 2015, responding to the growing global concern of indoor air pollution. Dyson points out that we breathe mostly indoor air, which can contain invisible, microscopic particles. Urban pollution, particulate matter, and pollen can infiltrate indoor spaces like offices, mix with pollutants from sources like cleaning products, and become trapped.

The new Dyson Pure Cool purifying fans—available in a large tower format for floors and a smaller desk format for tabletops and floors—automatically and effectively purify the whole room, capturing 99.95% of ultrafine particles, as small as 0.1 microns, and gases.

Dyson prioritizes real-world functionality when designing its purifying fans, going beyond standard test conditions. Paul Dawson, VP of Dyson Health and Beauty, emphasizes this focus, stating that Dyson creates technology that performs well in testing but, more importantly, delivers on its promises in real-world settings. He highlights the Dyson Pure Cool purifying fan’s comprehensive approach: sensing pollution automatically, capturing gases and ultrafine particles, and projecting clean air throughout the entire room, making it uniquely effective in whole-room purification.

Dyson Pure Cool fan features:

Sensing:

A new LCD display provides real-time information on the types of particles and gases the Dyson Pure Cool purifying fan is detecting. This data is analyzed by a unique Dyson algorithm that processes input from three sensors to display air quality readings. Lasers measure and identify ultrafine particles. Another sensor detects volatile organic compounds (VOCs), such as benzene and formaldehyde, which are emitted from sources like paint, candles, and furniture materials, along with nitrogen dioxide (NO2), a contributor to respiratory problems and acid rain. A third sensor tracks relative humidity and temperature.

Dyson meticulously calibrated the sensors in the Dyson Pure Cool purifying fans using scientific particulate readers. Thirty Dyson sensors were placed alongside air quality monitoring labs at King’s College London (UK) and Peking University (China) to understand their reactions and ensure consistency with academic equipment.

These sensors were exposed to real-world conditions for six months, enduring dirt, heat, wetness, and freezing temperatures, to gather long-term performance data. This rigorous process, collecting 288 measurements per second, provided over 5 billion data points, allowing Dyson engineers to apply the most effective calibration to the new generation of machines.

Capturing:

Dyson filters adhere to EN1822 and H13-A filter industry standards. The enhanced filter in the new Dyson Pure Cool purifying fan captures both particulate matter and gases. Dyson engineers increased the HEPA media by 60% in a taller, deeper filter and incorporated three times more activated carbon, which absorbs gases, odors, domestic fumes, and VOCs, while HEPA filters capture pollen, pet dander, dust mites, and tobacco smoke.

Nine meters of densely packed, sealed borosilicate microfiber filters capture 99.95% of particle pollution as small as 0.1 microns, including allergens, bacteria, pollen, and mold. Activated carbon filters, coated with trishydroxymethylaminomethane for enhanced absorption, remove gases such as NO2, formaldehyde, and benzene.

Projecting:

The Dyson Pure Cool purifying fan efficiently circulates clean air. By widening its oscillation to 350 degrees and employing Air Multiplier technology, the machine can project 290 liters of purified air per second, reaching every corner of the room.

The Dyson Pure Cool purifying fan introduces a new diffused airflow mode to avoid a cooling effect during winter. While the forward airflow mode cools the air, the diffused airflow or purification-only mode purifies without cooling.

App:

Dyson Pure Cool purifying fans integrate with the Dyson Link app 4.1, available on iOS and Android. The app allows users to monitor indoor and outdoor pollution, temperature, humidity, control the machine, and estimate remaining filter life.

These new machines also feature Over the Air Update Capability (OTA), ensuring Dyson owners benefit from the latest software advancements post-purchase.

Tests:

Dyson designs its purifying fans for real-world environments. Unlike some conventional air purifier manufacturers who rely on the clean air delivery rate (CADR) laboratory test, conducted in a small chamber with an additional fan, Dyson engineers developed the POLAR test.

The POLAR test utilizes a larger, more realistic living room setting without an extra fan, employing eight sensors in the room’s corners and one in the center to collect air quality data every 5 seconds. Evan Stevens, Head of Engineering for Dyson Environmental Control, explains that this method ensures accurate reflection of how users experience the machines in their homes.

Dyson has pioneered purifying fan advancements globally, leading new test methods in China, the world’s largest air purifier market. In January 2018, the China Household Appliance Standard and Technology Industry Alliance, an affiliation of China’s leading home appliance agency, released the first accreditation for intelligent air purifying fans based on tests developed at Dyson’s UK Technology Campus.

According to Dyson, pollution sources include:

Tree pollen, particulate matter, and city pollution can enter buildings and become trapped.

• Pollen: Microscopic pollen is released into the air by plants and flowers.
• Scented candles: Some chemicals in scented candles emit benzene and formaldehyde when burned.
• Furniture foam: Foam used in furniture can release formaldehyde gas.
• Indoor paints: Certain indoor paints contain volatile organic compounds released as gases during drying and potentially throughout their lifespan.
• Air fresheners: Some air fresheners contain volatile organic compounds and benzene, released with the fragrance when sprayed.
• Cleaning products: Household cleaning products can contain benzene, fumes, and odors.
• Carpets, rugs, and flooring: Some carpets, rugs, flooring, and their backing materials can emit formaldehyde when new and potentially throughout their life.

Details:

The new Dyson Pure Cool purifying fans are available in two versions: a larger tower format for floors and a smaller desk format for desktops, worktops, and floors. They come with a two-year parts and labor guarantee.

The Dyson Pure Cool purifying fans are available from shop.dyson.com.sg and major departmental and electrical stores starting in late May 2018.
