Dyson has announced a pair of new air quality monitors and purifiers, with the new ability to identify and monitor formaldehyde levels in your home, as well as destroy it.

The pair of devices come a year after Dyson’s first formaldehyde killers, but when these haven’t been able to monitor the amount of the compound in the surrounding air, newer models can.

They are called the Hot + Cool (HP09) and the Cool (TP09), with the first heating and cooling, while the last smaller model can only blow cold air. Both act as air quality monitors and automated air purifiers.

Like their predecessors, they use Cryptomelane catalytic filters to break down formaldehyde into water and carbon dioxide. A natural organic compound made up of hydrogen, oxygen and carbon, formaldehyde is produced by all life forms, but is also emitted by household products such as paint and furniture, and is considered a carcinogenic gas.

What’s new with the latest Dyson duo is how they use a solid-state sensor that can monitor formaldehyde levels in the air, whereas previous models could only track VOC levels ( volatile organic compounds) as a whole. This additional data should help homeowners better understand the air quality in their homes, and they’ll likely see how formaldehyde levels rise when they buy new furniture or paint the walls a new color. The release of VOCs like formaldehyde from new household items is known as outgassing.

Dyson Says Its Filters Capture 99.95% of Particles Passing Through It


Dyson also claims that the newer air purifier models are quieter than their predecessors, thanks to a change in the way air flows through products.

In addition to capturing formaldehyde, both products also attract bacteria, pollen, mold spores, allergens and other harmful materials found in domestic air. The company claims that 99.95% of particles as small as 0.1 microns that pass through the purifier are captured and retained by the filtration system.

Dyson has said again how much the new products will cost, but given that the old HP07 had a retail price of $ 600, we can expect the new HP09 to sell for an equally high price.
