It's the second Dyson to kill formaldehyde, but the first to actively monitor it

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-destroyers, but where those weren't able to monitor how much of the compound was in the surrounding air, the new models can.

They are called the Hot+Cool (HP09) and the Cool (TP09), with the former heating and cooling, while the smaller latter 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 formaldehyde down into water and carbon dioxide. A naturally occurring organic compound made of hydrogen, oxygen and carbon, formaldehyde is produced by all life forms, but is also emitted by household products like 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 the levels of VOCs (volatile organic compounds) as a whole. This extra data should help owners better understand the air quality in their home, and they will likely see how formaldehyde levels increase when they buy new furniture or paint the walls a new color. The releasing of VOCs like formaldehyde from new household items is known as off-gassing.

Dyson also says the new models of air purifier are quieter than their predecessors, thanks to a change in how air flows through the products.

As well as capturing formaldehyde, the two products also draw in bacteria, pollen, mould spores, allergens and other harmful material found in household air. The company claims that 99.95 percent of particles as small as 0.1 microns that pass into the purifier are captured and retained by the filtration system.

Dyson is yet say how much the new products will cost, but given the older HP07 had a retail price of $600, we can expect the new HP09 to command a similarly large price tag.
