For whole-room purification – capturing 99.97% of fine particles, 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™ app⁵ – 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 32 feet.¹ 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 air purifier range is engineered to remove 99.97% of fine particles, such as dust and allergens*. It also captures odors and gases² like benzene, nitrogen dioxide, and even formaldehyde.⁺
The Dyson Purifier Big+Quiet Formaldehyde has our most advanced filtration system. We recommend replacing the 360° HEPA H13-grade filter after using it for up to five years or sooner. The Activated carbon filter should be replaced every two years, or sooner if required. The Selective Catalytic Oxidisation (SCO) filter is permanent and never needs replacing.
The Dyson Purifier Big+Quiet Formaldehyde has been designed to work from the corner of a room, at least three feet 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.
