Dyson is ready to capture your Formaldehyde

The new Dyson Air Purifier will get rid of the nasty formaldehyde in your house.

If you don’t know what Formaldehyde is, my quick Googling says it is nasty stuff in lots of building materials that is bad for us. So purifying that out sounds good to me. You can read more of Dyson’s wording below if my summary of Googling doesn’t help.

Of course this premium air purifier comes with all the fancies like voice activation, an app to control from your phone, and a whole lot more.

This new purifier will be available in New Zealand from May 2021 at Dyson and retailers including Noel Leeming, Heathcote, Farmers, Harvey Norman and JB-Hifi.

The Indoor Generation

Every day, humans breathe up to 9,000 litres of air, and even before the COVID-19 pandemic spent as much as 90% of their time indoors. As our homes increasingly become spaces where we work and exercise as well as sleep and play, the quality of the air we breathe in all aspects of our routine is non-negotiable.

There are a number of indoor pollution sources, which release pollutants like PM10, PM2.5, VOCs, NOand formaldehyde into the air. Sources of pollution are present in all aspects of our daily lives, whether that be PM2.5 emitted when cooking, VOCs released from cleaning products or the continuous off-gassing of formaldehyde from our living room furniture. Tirelessly improving and constantly iterating, Dyson’s new Purifier Formaldehyde range reflects the latest technology in three core areas: sensing, filtration and acoustics.

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 sensors can be gel-based and may deteriorate gradually as they dry out over time. Using an 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 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.

Whole-machine HEPA filtration

In Dyson’s new purifiers, it’s not just the filter that meets HEPA H13 standard, but the whole machine. It captures 99.95% of particles as small as 0.1 microns such as allergens, bacteria, H1N1 virus*, pollen and mould spores. Dyson engineers took a forensic approach to achieving a 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.

Dyson Purifier Cool: Acoustically engineered to be 20% quieter

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% quieter. 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 room. Auto mode enables the machine to maintain a preferred room temperate and air quality levels, while the machine can be entirely controlled by the Dyson Link App and activated by voice control.  

Engineered for real homes

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.
