Dyson unveils new air purifier for offices & classrooms

With millions returning to work and education, cleanliness in work spaces and schools has never been so high on the agenda.  The new Dyson HEPA Purifier Formaldehyde integrates all new solid-state formaldehyde sensors and fully-sealed HEPA 13 standard filtration¹ in a machine that is 20% quieter², ensuring a cleaner space.

 

  • Today, Dyson unveiled its latest generation of purification, designed to tackle indoor pollution within workspaces and classrooms as well as the home. 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.  

     

    Tireless and ever-dissatisfied, Dyson engineers have re-engineered the machine airflow pathways to achieve fully-sealed HEPA 13 standard filtration³ – 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% quieter⁴, without any compromise on purification performance to reduce unwanted disruption in offices and schools.

"As we venture back to offices, classrooms, hotels, gyms and other public spaces, we all want reassurance that these spaces are clean. As consumers, we trust that our work, leisure and education spaces are being properly 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 Purifier Formaldehyde does exactly that and more.”

- Alex Knox, Vice President of Environmental Care

  • Cleaner spaces

    Every day, humans breathe up to 9,000 litres of air,⁵ and in many countries spend as much as 90% of their time indoors⁶. With most of the world’s population experiencing one third of their adult life at work⁷, facilities managers and employers alike have a responsibility to ensure the air that is being breathed in these spaces is clean.

     

    Adequate ventilation, increased airflow and avoiding touchpoints are top of mind for facilities managers and consumer 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. These pollutants can include PM10, PM2.5, VOCs like formaldehyde and NO2. From particulates released by office printers to formaldehyde off-gassing from furniture, Dyson has engineered its new range with these real-life spaces in mind.

    Full-machine HEPA filtration

    In Dyson’s new purifiers, it’s not just the filter that meets HEPA H13 standard, but the whole machine⁸. It captures 99.95% of particles as small as 0.1 microns such as allergens, bacteria, H1N1 virus⁹, pollen and mould spores¹⁰. Dyson engineers took a forensic approach to achieving a fully-sealed machine, creating high pressure seals at an additional 24 critical points to prevent dirty air from bypassing the filters and carrying pollutants back into the room.

  • Precise formaldehyde sensing and destruction

    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 Oxidisation (SCO) filter continuously destroys formaldehyde at a molecular level¹¹. 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.

    Acoustically engineered to be 20% quieter¹²

    Dyson engineers increased efforts to further reduce the sound output of the Dyson Purifier Cool while maintaining purification performance. Through an iterative design, test, build process managed at the Dyson Malaysia Development Centre’s in-house acoustics chamber, the machine was re-engineered to be 20% quieter¹³. To achieve this noise reduction, Dyson engineers refined the overall airflow path by widening the aperture (slot in which the air exits the machine) and its geometry was improved. This reduced the amount of friction between the air and surface of the machine, resulting in less sound. Noise was reduced from 64 to 61 decibels at max fan speed.

    Air Multiplier Technology

    Using Dyson Air Multiplier™ Technology, the machine can project purified air to every corner of the room¹⁴. Auto mode enables the machine to maintain a preferred room temperate and air quality levels, while the Dyson Link App and voice control activation help avoid touchpoints and possible contamination¹⁵.

    Engineered for real spaces

    Dyson Purifier machines are engineered for real spaces. The industry standard for testing air purifiers measures performance using a laboratory test conducted in a compact chamber 12m² in size, with a ceiling fan to circulate the air and one sensor inside the room measuring air quality. For more representative testing, Dyson’s POLAR test is based on a larger room size of 27m² with no added fan and uses eight sensors in the corners of the room and one sensor in the centre to collect air quality data.
