Dyson’s most recent purifier comes with enhanced filtration, providing twice the airflow of previous Dyson purifiers and establishing a new benchmark in acoustics, pushing indoor purification to new limits.
Dyson’s quietest yet most powerful purifier: The Dyson Purifier Big+Quiet Formaldehyde is borne of Dyson’s longstanding expertise in airflow, acoustics, filtration and compressors.
Cone Aerodynamics: New airflow delivery system offers more than double the airflow of previous models, up to 87 litres of airflow per second of purified air up to 10 meters2. New CO2 sensor indicates when to ventilate.
Re-engineered motor bucket: Ensures quiet operation – meticulous re-engineering incorporating ingenious acoustic solutions including a Helmholtz silencer and labyrinth seal.
Improved three-phase filtration system: Capturing up to 99.95% of ultrafine particles, removing 3x more NO2 compared to previous Dyson carbon filters and permanently destroying formaldehyde, with five-years HEPA filter life.
New Cone Aerodynamics: Powerful projection in large spaces up to 100m2
Introducing the Dyson Purifier Big+Quiet Formaldehyde, a groundbreaking advancement in air purification that tackles the issue of insufficient airflow projection in spacious areas. Unlike traditional large-format purifiers that disperse air upwards, Dyson engineers have devised a new energy-efficient and low-pressure air delivery system called Cone Aerodynamics to achieve superior results.
Cone Aerodynamics uses the Coanda effect to merge two streams of air over a smooth surface, resulting in a powerful and condensed jet of air that can be projected of up to 10 meters, with minimal noise. It delivers more than double the airflow of the previous generation Dyson Purifiers. Powerful projection is critical to ensure that the machine effectively delivers clean air to every corner and displaces dirty air back towards the filter. The Dyson Purifier Big+Quiet Formaldehyde projects purified air at angles of 0°, 25° or 50° depending on user preference.
Quiet even at full power
Dyson’s in-house team of acousticians and noise and vibration engineers re-engineered the motor bucket to achieve a low-pressure, high velocity system for the Dyson Purifier Big+Quiet Formaldehyde to project maximum airflow with minimum noise.
Sensing and monitoring
Equipped with an array of built-in sensors, the Dyson Purifier Big+Quiet Formaldehyde incorporates a distinctive Dyson algorithm that constantly cross-references data every second. This algorithm thoroughly examines the air quality and promptly adapts to environmental variations, ensuring efficient purification. The purifier conveniently displays real-time results on its LCD screen and through the MyDyson app, which also functions as a remote control for convenient operation even when you’re away from home. Additionally, the app allows you to schedule and monitor the purification process effortlessly.
Real-World Testing
At Dyson’s Hullavington campus, engineers have constructed a significantly larger test chamber spanning 100m2. This chamber is meticulously outfitted with 36 sensors to deliver accurate measurements of the purifier’s performance in purifying the air, simulating conditions akin to a spacious, open-plan living area.
