Frequently asked questions
The Dyson Purifier Big+Quiet Formaldehyde is our most advanced, quietest, and most powerful air purifier. As our latest top-of-the-range purifier, it uses cone aerodynamics to deliver powerful, long-range air projection – circulating purified air and driving even distant pollutants back through sealed filters. For whole-room purification – capturing 99.97% of ultrafine particles², even in large spaces.¹ You can control your air quality, wherever you are. At the touch of a button you can monitor the air quality levels in your home using the MyDyson™ app⁶ – viewing in real-time the benefits of owning an air purifier.
Not all purifiers are equal. Getting the right size purifier, with the best projection is essential to ensure it will effectively purify the air in your space. We've tested the Dyson Purifier Big+Quiet Formaldehyde extensively – to ensure the sensors, filtration system and motor work together to purify a large living space. It has the projection power to purify spaces up to 100m². The Dyson Purifier Big+Quiet Formaldehyde also has our largest ever filtration system – and the 360° HEPA H13-grade filter doesn’t need replacing for up to 5 years.

The Dyson Purifier Big+Quiet Formaldehyde has been designed to work from the corner of a room, at least one metre away from the wall. For optimal performance we recommend projecting air either along a wall or across the room. You can adjust the angle of projection to suit your preference.
The Dyson Purifier Big+Quiet Formaldehyde has discreet wheels, which aren’t visible when the machine is upright. These wheels are designed for hard floors – so you can move your purifier around easily.
¹ The ability of purifying a large room up to 100m1 (10mx10m) proven from Computational Fluid Dynamics (CFD) modelling, with the purifier placed in a corner of the room running at the maximum flow and horizontal projection reaching 10 metres to fully mix the room. The projection distance was measured from internal flow reach testing under the maximum directional airflow. The actual performance in real life conditions may vary.
² Tested to IEST RP-CC001.
³ Tested to JEM 1467 (acetic acid, acetaldehyde, ammonia), GB/T18801 (formaldehyde, benzene) and DTM-003282 (NO2). Gas capture rates vary.
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.
