Dyson is releasing a new air purifier designed to address the problem of indoor air quality in professional settings and shared spaces.

The Dyson HEPA Big+Quiet Formaldehyde purifier uses cone aerodynamics to deliver up to 90 litres of airflow per second– double the airflow of previous Dyson models. 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 purifies air across large spaces, with minimal noise.

Designed with a fixed projection angle of 50 degrees to reduce airflow interference and operating at 55.6 decibels of noise on maximum airflow speed, the Dyson HEPA Big+Quiet Formaldehyde purifier is Dyson’s most powerful and quiet purifier yet.

The Dyson HEPA Big+Quiet Formaldehyde purifier also incorporates a CO2 sensor, which provides live, colour coded readings of CO2 levels on the 1.44-inch LCD screen. If CO2 levels exceed recommended levels, the screen will show the reading in red, indicating when ventilation is required.

The Dyson purifier features a fully sealed filtration system to HEPA H13-grade, capturing 99.95% of particles as small as 0.1 microns and ensuring purified air is projected back into the room. Its three-phase filtration system is engineered to capture ultrafine pollutants, remove gases and destroy formaldehyde.

An activated carbon filter combats NO2 specifically, which can be emitted from cooking in open-plan kitchen facilities, or by entering indoor environments from outdoor sources such as nearby road traffic.

The Dyson Selective Catalytic Oxidation (SCO) filter has a unique coating, with the same structure as the Cryptomelane mineral. Its billions of atom-sized tunnels break down formaldehyde molecules into water and CO2 and then re-generates with oxygen from the air to destroy formaldehyde continuously.

The industry standard test for purifiers, Clean Air Delivery Rate (CADR), is tested in a small test chamber of 12m2 with just one sensor and artificial air mixing. For this purifier, Dyson engineers constructed a 100m2 test chamber equipped with 36 sensors to measure the machine’s ability to thoroughly and evenly clean the equivalent of a large open-plan space.

The Dyson HEPA Big+Quiet Formaldehyde purifier is available for businesses to purchase from $1,249 ex GST by calling 1800 426 337 or emailing AUCommercial@dyson.com. All Dyson machines come with a two-year warranty covering parts and labour.
