Dyson has released its latest generation of purification, designed to tackle indoor pollution within workspaces and classrooms as well as the home.
The range will be available in Australia from May, 2021. Conventional ventilation, air circulation and air conditioning systems in work and classroom spaces may not have adequate HEPA filtration.
Dyson’s latest purifiers are engineered to provide high-quality filtration and powerful projection to support existing HVAC systems and provide cleaner, purified air throughout office and classroom spaces.
Dyson engineers have re-engineered the machine airflow pathways to achieve sealed HEPA 13 standard filtration - not only ensuring that no air bypasses the filter, but blocking any potential leak points through which dirty air might enter the airflow.
A new, solid-state formaldehyde sensor works alongside Dyson’s unique algorithm to precisely monitor formaldehyde levels – intelligently ignoring other gases which are detected by a dedicated VOC sensor. Improvements of the airflow journey have made the machine 20 per cent quieter without compromising on purification performance.
The company’s vice president of environmental care, Alex Knox, said consumers want to be reassured that public spaces are clean and hygienic.
He said these spaces need to be maintained with technology that genuinely works.
“Dyson has engineered a machine to respond directly to these concerns – promising cleaner, purified air throughout offices and classrooms. The Dyson HEPA Cool Formaldehyde does exactly that and more,” Knox said.
Adequate ventilation, increased airflow and avoiding touchpoints are top of mind for facilities managers and consumers alike. Increasing ventilation by opening windows can cause poor outdoor air to come inside, while built-in ventilation systems may not have adequate filtration, so airborne pollutants are simply blown around the room.
In addition to the existing particle, NO2, VOCs, temperature and humidity sensors, the integration of an intelligent formaldehyde sensor ensures precise sensing of the pollutant for the lifetime of the machine.
Formaldehyde is a colourless gas pollutant, released by furniture and wooden products which use formaldehyde-based resins and commonly associated with new or refurbished spaces. Formaldehyde is 500 times smaller than 0.1 microns, which makes it particularly difficult to capture but leads to long-term exposure if left undetected due to off-gassing.
Formaldehyde sensors can be gel-based and may deteriorate gradually as they dry out over time. Using a solid electro-chemical cell, the Dyson formaldehyde sensor does not dry out and its unique intelligent algorithm cross-checks data every second, selectively sensing to avoid confusion with other VOCs.
Dyson’s Selective Catalytic Oxidation (SCO) filter continuously destroys formaldehyde at a molecular level.
The catalytic filter has a unique coating, with the same structure as the Cryptomelane mineral. Its billions of atom-sized tunnels are the optimal size and shape to trap and destroy formaldehyde, breaking it down into tiny amounts of water and CO2 .
It then regenerates from oxygen in the air to keep destroying it continuously without ever requiring replacement. Using Dyson Air Multiplier Technology, the machine can project purified air to every corner of the room.
Auto mode enables the machine to maintain a preferred room temperature and air quality levels, while the Dyson Link App and voice control activation help avoid touchpoints and possible contamination.
