Auto Mode

In Auto mode our purifier reacts automatically to capture pollutants, only using energy when needed. With live air quality reports displayed on the LCD screen or MyDyson app.[7]

Advanced Three-stage Filtration With Hepa H13

The HEPA H13-grade filter with activated carbon captures gases, 2 odours, ultrafine dust, allergens, bacteria and 99.95% of particles as small as 0.1 microns.4

Fully Sealed Whole-machine Filtration

In our latest purifiers, it’s not just the filter that meets HEPA H13 standard, it’s the whole machine. So what goes inside, stays inside.[8]

Ceramic Plates for Fast Heating

PTC ceramic plates heat the air as it’s projected, with built-in thermostats which can save you up to 30% in running costs while maintaining room temperature. 11

Destroys Formaldehyde in Billions of Catalytic Tunnels

Dyson’s unique SCO filter continuously traps and converts formaldehyde into water and CO2.5 And it self-regenerates, so it never needs replacing.

What’s in the Box:

• Remote Control: Curved and magnetised to store neatly on the machine
• 360° Glass HEPA and Activated Carbon Filter: Sealed HEPA filter made from borosilicate microfibres, pleated hundreds of times, to capture 99.95% of ultrafine particles[3] with activated carbon filter to remove gases and odours

Notes

4. Third party full machine testing based on GB/T 18801-2022 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.

6. Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.

9. After reaching target temperature and maintaining it. Tested in a 35 m[3] chamber when using the hot air mode and the product setting temperature is 25 °C. Comparing with continuous operation with power consumption of 2050W. Real life results may vary depending on room insulation.
