Product details
The Dyson Purifier Hepa Big+Quiet Formaldehyde efficiently purifies the air in large rooms, distributes it with a range of over 10m¹ and is particularly quiet.
Distributes
Distributes a powerful airflow
Distributes
Distributes a powerful airflow
of purified air and creates the necessary air circulation to purify the entire room air at the same time¹.
Powerful and quiet
The powerful airflow creates a pressure difference in the appliance and allows the air purifier to operate quietly even at the maximum setting.
Fully sealed HEPA H13 filter system²
The fully sealed HEPA H13 filter removes 99.95% of particles as small as 0.1 microns from the air.
Decomposes formaldehydes continuously⁴
The unique catalytic filter breaks down formaldehyde into billions of small molecular-sized tunnels⁴ and never needs to be replaced.
Automatically detects the CO2 concentration in the room air and generates reports in real time⁵
A warning appears on the display indicating that the room should be ventilated as soon as the CO2 concentration in the room air exceeds 1,500 ppm.
Simple filter change
Thanks to the hygienic filter change, you never come into contact with the filters. Instead, they can be easily disposed of with just one click.
HEPA filter with a service life of 10 years⁶
21 metres of borosilicate glass microfibres have been folded over 450 times. We recommend replacing the HEPA filter every 10 years.⁶
Dyson's most energy-efficient air purifier
The pressure difference in the air ducts, in combination with an optimised compressor, ensures high energy efficiency: the cleaning performance is over 8 m³ per hour, per watt.
2 year guarantee
1 Tested in a room measuring 70 m² (11.9 m x 5.9 m), with the air purifier in one corner of the room and the pollutant source in the opposite corner. There were 45 sensors in the room to determine the distribution and air purification for PM2.5. Results may vary in practice.
2 Particle test by DEHS oil according to EN1822 in a test chamber according to ASTM F3150. Tested in MAX mode by IBR Laboratories (USA) for filtration efficiency above 99.95 %.
3 Tested for filtration efficiency rate (EN1822, ISO29364) at 0.1 micron.
4 Test of the entire device is based on the cumulative clean mass (CCM) formaldehyde test according to GB/T 18801-2015 with continuous injection until the formaldehyde CADR (Clean Air Delivery Rate) value reaches a plateau.
reaches a plateau. Results may vary in practice.
5 Values defined by Dyson are based on scientific literature (Lowther et al. (2021) Environments). Ventilation warning appears at a CO2 concentration of 1,500 ppm or higher.
6 The filter service life is determined by dividing the total dust holding capacity by the annual dust intake. Annual dust intake calculated using the formula for calculating the daily mass according to GB/T 18801. Results may vary in practice.
