Dyson Pure Cryptomic Purifiers Promise to Eliminate Formaldehyde

Dyson Air Purifier

Dyson announced its latest purifying fan Tuesday, a device capable of not only cooling a room but heating it as well. The Dyson Pure Hot+Cool Cryptomic is the company’s first device to continuously destroy formaldehyde that’s been released into the air in your home from household items. Tucked inside the cylindrical body is a new catalyst panel, which Dyson says can take harmful formaldehyde and convert it into harmless water and carbon dioxide.

Its previous air purifiers could only capture it, not get rid of it altogether.

Compared to smog, cooking smells, and other particulates, formaldehyde might not be on your list of home or office air worries. Turns out, it’s surprisingly prevalent indoors since it’s off-gassed from a variety of sources. Furniture, air fresheners, electronics, cleaning products, and more can all release the colourless, odourless gas.

As for why you don’t want formaldehyde in your home, Dyson points to US EPA research suggesting it can trigger ear, nose, and throat irritation, or even – albeit at sufficiently high levels – some cancers.

Essentially the device is using the mineral Cryptomelane as a catalyst to trap formaldehyde in the air. Cryptomelane has billions of atom-sized tunnels, which are the perfect size to trap and destroy formaldehyde in the air. The destruction is done through oxidation, the company said.

Formaldehyde has historically been more difficult to capture as its particles are too small. The new Cryptomic filter never has to be replaced and is built into a plate at the base of the devices.

Apart from the formaldehyde-targeting technology, the new Pure range has many of the same features as the rest of Dyson’s purifiers. You’ll still find the company’s hallmark Air Multiplier bladeless fan and 350-degree oscillation. The timers, night mode and Link app are the same, and the purifiers can tilt at a 45-degree angle if you want to aim the airflow higher or lower.

Aside from keeping your house’s air clean, the Dyson Pure Cool Cryptomic air purifier can be used to cool your home with an oscillating fan and the Dyson Pure Hot+Cool Cryptomic works as both a fan during cooler weather and a heater in the cold.

There are four models in the line-up, two colours each of the Dyson Pure Cool Cryptomic and the Dyson Pure Hot+Cool Cryptomic; the former is a fan only, while the latter can also operate as a room heater. Each uses the same particulate filter as the previous Pure models, which the company says can capture 99.97-percent of allergens and pollutants, as small as 0.3 microns. This HEPA filter is designed to trap things like bacteria, pollen, and mould spores, while a redesigned activated carbon filter snags odours, domestic fumes, and gases like nitrogen dioxide and benzene.

While the HEPA and carbon filters need replacing roughly every twelve months, the formaldehyde catalyst filter lasts the lifetime of the purifier itself.

Using Dyson’s app, you can also monitor the device and the pollution in your home from afar. Inside your house, an included remote control allows you to control the device hands-free. Both the Dyson Pure Cool Cryptomic and Dyson Pure Hot+Cool Cryptomic are available starting Tuesday for $649.99 and $749.99, respectively. Both come in in white/gold and gunmetal/bronze.
