Introduction to Dyson's Latest Air Purifier Models and Technology

Dyson has recently launched new air purifier models with advanced technology for removing indoor air pollutants. These new Dyson Purifier Formaldehyde models build upon previous Dyson air purifiers by adding the ability to sense and destroy formaldehyde specifically.

Dyson is known for its innovative home appliance products like vacuums, hair care tools, and environmental care devices. The new purifiers exemplify Dyson's commitment to using technology to create market-leading performance and health benefits.

Overview of Dyson Product Categories

Dyson makes several categories of innovative home products including hair care tools, floor care vacuums, and environmental care appliances like air purifiers, heaters, humidifiers, and fans. The new Dyson Purifier Formaldehyde models add exciting new air cleaning capabilities while retaining Dyson's signature iconic product design.

Focus on Environmental Care Products

Dyson environmental care products aim to improve indoor air quality by removing pollutants. Before the new purifiers, Dyson air purifiers could capture particulates like dust and allergens as well as gases like VOCs. The launch event highlighted how the new purifiers take Dyson's indoor air quality mission further by also eliminating formaldehyde specifically.

Sensing and Capturing More Indoor Pollutants

The new Dyson air purifiers retain capabilities to sense and capture particulates down to microscopic sizes as well as odorous VOCs emitted from products commonly used indoors.

Additionally, a specialized formaldehyde sensor allows precise detection of gaseous formaldehyde concentration in indoor spaces like homes.

Particulates, VOCs, and Now Formaldehyde Too

Previous Dyson purifiers could sense particulates like pet dander and smoke as well as VOCs from household cleaners, candles, and off-gassing from new furniture or construction materials. The formaldehyde sensing capability now allows homeowners to understand if pressed wood products and composites in furniture, flooring, cabinets, and more are degrading indoor air through formaldehyde off-gassing.

Precise New Formaldehyde Sensor

The proprietary solid-state formaldehyde sensor in the new purifiers avoids common problems with alternative liquid electrolyte sensors. It precisely detects formaldehyde without false alerts from other household scents and maintains consistent sensitive performance over the product lifetime unlike gel-based sensors.

Destroying Formaldehyde at the Molecular Level

The new Dyson purifiers move beyond just capturing formaldehyde gas like previous models captured other pollutants. An innovative Selective Catalytic Oxidation (SCO) filter actually destroys formaldehyde at a molecular level through a chemical reaction.

Selective Catalytic Oxidation (SCO) Filter

The SCO filter contains a Cryptomelane mineral catalyst optimized to interact with formaldehyde molecules specifically. When formaldehyde contacts the catalyst surface, a chemical reaction transfers oxygen to break formaldehyde into carbon dioxide and water vapor - completely eliminating the pollutant.

How SCO Filter Works

The key innovation in the SCO filter is that the formaldehyde is not simply captured and stored like other gas filters. The Cryptomelane mineral catalyst provides renewable oxidative power to destroy formaldehyde at a molecular level into harmless byproducts, avoiding degradation over time.

Achieving Whole-Machine HEPA Filtration

In addition to the innovative molecular formaldehyde destruction, Dyson engineers enhanced the new air purifiers to provide medical-grade H13 HEPA filtration across the entire machine, not just the filter elements themselves.

Identifying and Sealing Leak Points

Extensive internal sealing assessments identified 24 potential internal airflow leak points in the purifiers. Adding high pressure seals at each of these locations, combined with particulate filter seals, ensured no unfiltered bypass to achieve full machine HEPA certification.

20% Quieter Operation

Alongside the major technical upgrades to filter more pollutants, Dyson acoustic engineers succeeded in significantly reducing noise outputs from the new purifier models through airflow optimizations.

By smoothing internal airflow pathways and allowing motor speed reductions, sound testing verified a 20% decrease in noise generation from the tower sized models.

Smoothing Airflow to Reduce Turbulence and Noise

The acoustic improvements emerged from extensive design iterations focused on optimizing internal air channels. Smoother pathways eliminate turbulence that creates disruptive noise. This also boosted energy efficiency, further enabling motor speed reductions for less mechanical noise.

Conclusion and Next Steps

Dyson continues innovating to improve indoor air quality through purposeful technology upgrades. The new Dyson Purifier Formaldehyde range adds unique formaldehyde destruction and full system filtration capabilities beyond previous models.

Consumers can explore these new technologies in Dyson stores globally or online through virtual demonstrations and additional launch event media. Commercial variants of the new purifiers will also bring Dyson's indoor air expertise to business spaces.


Q: What indoor pollutants can the new Dyson air purifiers handle?
A: The new Dyson Purifier Formaldehyde range can sense and capture particulates, VOCs, and formaldehyde. It also destroys formaldehyde at the molecular level using a special SCO filter.

Q: How does Dyson destroy formaldehyde?
A: Dyson uses a Selective Catalytic Oxidation (SCO) filter with a Cryptomelane mineral that interacts with formaldehyde molecules. This filter constantly replenishes itself using oxygen in the air to oxidize formaldehyde into harmless CO2 and H2O.

Q: What is whole-machine HEPA filtration?
A: This means that in addition to a HEPA filter, the entire air purifier achieves HEPA 13-grade filtration. Dyson engineers sealed 24 potential leak points inside the machine to prevent bypass.

Q: How did Dyson make the air purifiers quieter?
A: By smoothing the airflow between the motor and outlet to reduce turbulence. This allowed lowering the motor speed while maintaining air purification performance.

Q: Where can I learn more about the new Dyson air purifiers?
