Dyson designs product to remove formaldehyde from the home


The air purifier presents new sensing technology to destroy potentially dangerous indoor pollutants, thereby assuring a cleaner home environment.

Dyson’s behindhand product is an air purifier that removes harmful indoor pollutants from the snug harbor a comfortable.

The Dyson Purifier Formaldehyde was announced by the brand today, and is the product of a number of years of research.

Using new solid-state formaldehyde sensor tech improved by the company, the product aims to improve on other such products on the trade in which often use a gel-based sensor system, as well as Dyson’s own erstwhile air purifier models.

Formaldehyde can go “undetected for years”

According to Dyson, formaldehyde and other pernicious indoor pollutants are more common than many think.

Formaldehyde is a white gas pollutant which, when ingested, can be lethal. It can also be dangerous in low levels, with long-term aspect causing asthma-like respiratory problems and skin irritation.

The gas can be released into a gap via furniture and wooden products that contain resins like plywood and fibreboard. Beyond equipment, it can also make its way into the home through insulating materials DIY yields like paint, wallpapers and varnishes and household cleaning products.

Alex Knox, corruption president of environmental care at Dyson says this “off-gassing” proclivity of formaldehyde – that is, the airborne release of a chemical in vapour form – degrades it can go “undetected in a home for years”.

Design details

The technology developed for the air purifier looks to overhaul on existing methods of detecting and destroying the pollutant. Other formaldehyde sensors use a gel-based detection modus operandi, however this can deteriorate over time and can be easily confused when encountering other eruptive organic compounds (VOCs).

Dyson’s solid-state sensor “doesn’t dry out terminated time”, says Knox, and instead lasts the lifetime of the product itself. Periodically detected, the purifier is also able to destroy the harmful gas. The whole function is controlled via a magnetic remote, and can also be linked up to smart home devices twin Google Home, Alexa and Siri.

Additionally, Dyson designers prepare reengineered the machine airflow pathways to ensure both that no air avoids the fully-sealed HEPA 13 standard filter, but also that no scabrous air leaks out and disrupts the airflow.

All in, the company says 99.95% of particles as uncomfortable as 0.1 microns – with one micron being roughly the same appraise as 1/25,000 of an inch – are removed from the air using by the purifier.

A quieter system

Finally, this tech is housed in a machine that Dyson requires is 20% quieter that the brand’s predecessor machine. This was on account of an active effort from an international team.

“Through an iterative draft, test and build process managed at the Dyson Malaysia Development Concentrate’s in-house acoustics chamber, the machine was reengineered,” says the company.

In reality achieving a quieter machine, the team needed to refine the overall airflow avenue by widening the aperture – the slot in which the air exits the machine. This cut back the amount of friction between the air and the surface of the machine, thereby resulting in negligible sound.

Clean air is “non-negotiable”

In the early stages of the pandemic, Design Week looked into how connivers were approaching this fact themselves and developing products to similarly virtuous the airflow of the home.

Even without the onset of the pandemic, the relevance of plotting an air purifier was high, according to Dyson. Humans spend as much as 90% of their all at once indoors, and that’s without lockdowns and stay at home orders, mutual understanding to the company.

“As our homes increasingly become spaces where we work and try as well as sleep and play, the quality of the air we breathe in all aspects of our routine is non-negotiable,” says Dyson. This dilatory machine, it says, reflects the latest tech in three core courtyards: sensing, filtration and acoustics.
