Review: Dyson Pure Cool Link

Dyson Pure Cool Link is the most compact air purifier capable of cleaning the air in large rooms

It is hard not to get attached to the design of Dyson’s Pure Cool Link. To begin with, it’s the most compact air purifier capable of cleaning the air in large rooms. Second, there is no traditional blade fan, which means you can put your hand through the halo-like top design of the device. Third, it has an oscillation mechanism too. The small display (fan speed, Wi-Fi, etc.) sits on the base. The top of the purifier integrates a magnet for the compact remote. The absence of control buttons on the Pure Cool Link’s body gives the design a clean, sophisticated look. You can either control this via the remote, or from the Dyson Link app (Android and iOS).

The 360-degree Hepa (high-efficiency particulate air) borosilicate filter holds more than 6m of borosilicate microfibres and has a layer of Tris-coated (also known as tromethamine) graphite that acts as a buffer solution. With all this in place, the Dyson purifier can capture particles as small as 0.1 microns—these are 100 times smaller than the human hair—and effectively eliminate gases, fumes, ozone, benzene, etc. The 0.1-micron particles not only go into the lungs but can also enter the bloodstream. Most Hepa filters can capture particles as small as 0.3 micron only. 

Dyson’s air multiplier technology, which dictates the Pure Cool Link’s unique look too, is also used in jet engines. The air is pushed through an annular loop, enabling a consistent air flow. The fan gets noisy upwards of speed 7 (max speed is 10). The device was able to clean the air in a bedroom about 18 sq. m in size, from a very unhealthy 141g/m3 of PM 2.5 to 9g/m3 in 15 minutes.

Unlike other air purifiers, the more pedestal fan-like air flow means that this does create some draft, which means it can feel a tad uncomfortable in winter. In other words, you would have to reposition it in the room. 

The Dyson Link app is the slickest for any smart purifier, by far. You get outdoor and indoor air quality statistics, remote controls and air quality variation graphs. It is able to specify how sensitive you are to particles and pollutants, and allows the purifier to modify the air quality target and tweak the auto mode settings. 

The Dyson Pure Cool Link is significantly superior to similarly priced competition, purely for its finer air cleaning capabilities and the simplicity of operation.
