Frequently asked questions
What’s new about the Dyson Purifier Big+Quiet range?
While our current generation purifiers circulate clean air around the whole room¹, the Dyson Purifier Big+Quiet projects air over 32 feet, creating the circulation power purifying large spaces.¹ Featuring our largest ever filtration system, the purifier captures 99.95% of ultrafine particles. It’s also acoustically engineered to operate quietly – even at its highest power setting.
What kind of spaces can the Dyson Purifier Big+Quiet Formaldehyde purify?
We've tested the Dyson Purifier Big+Quiet extensively – to ensure the sensors, filtration system and motor work together to purify a large living space. It has the projection power to reach up to 32 feet.¹
How does the Big+Quiet purify a whole room?
We’ve re-engineered the Big + Quiet to deliver three key features to purify large spaces.¹ Long range projection creates the circulation power to draw even-distant pollutants back to the purifier. Our integrated sensor system detects and reports pollutants from around the room. Finally, three phases of purification sit within the machine, full sealed to HEPA H13 grade.⁹ Capturing gases², odors, ultrafine particles and destroying formaldehyde.⁺ Purified air is then projected back into the room and the cycle repeats.
What is formaldehyde and why is it important?
Formaldehyde is a colorless and potentially harmful gas found in some household furnishings and products. Sources of formaldehyde include woods, glues, paints, varnishes, air fresheners, mattresses, household cleaners, and some fabrics found in household flooring, carpets and furniture. Formaldehyde can continue to be emitted for years, which means the gas can build up in your home. The Dyson Purifier Big+Quiet Formaldehyde range features a lifetime Selective Catalytic Oxidation (SCO) filter which traps formaldehyde in tunnels, breaking it down into water and CO₂. and never needs to be replaced.⁺
Can I leave my Dyson air purifier on all the time?
Dyson purifiers perform at an optimal level when used in Auto mode. This mode means the purifier will constantly monitor your air quality, automatically sensing and capturing pollutants. It will adjust airflow speed, and only purify or use energy when it’s necessary. The Dyson Purifier Big+Quiet range offers enhanced energy efficiency, providing nearly double the clean air delivery rate per watt, compared to our current generation of purifiers.
