New Dyson Pure Cool air purifiers launched

We take a look at Dyson's new Pure Cool air purifiers - are they the best you can buy?

Dyson has launched two new air purifiers ready for Spring 2018 – the Pure Cool tower and desk fan. The company says that they are the most advanced air purifiers it has launched.

Despite the uncanny visual similarities to Dyson’s previous air purifiers, launched in 2015, the Pure Cool tower and desk fan are packed with some really exciting and useful features.

Prices start at £399.99 for the desk fan and go up to a whopping £499.99 for the tower. This is £50 more than the original 2015 models.

So are these Dyson air purifiers worth the money? Find out our first impressions of the Dyson Pure Cool desk fan.

What’s new for Dyson’s Pure Cool air purifiers?

Dyson has seen an explosion of growth in Asia in recent times – particularly in China, the world’s largest market for air purifiers. That’s perhaps unsurprising when you consider that only 84 of 338 Chinese cities measured reached the national standard of air quality in 2016.

So it makes sense that Dyson has teamed up with likes of Peking University in Beijing, as well as King’s College London, to help calibrate some of the new tech that features in these purifiers.

The new Pure Cool tower and desk fans have LCD screens that feed back in real time the pollutants that are present in your house.

The Pure Cool also features a new filter – Dyson claims it has a capture rate of gas and microscopic allergens of 99.95%. The firm also says that its new Air Multiplier technology will project the clean air across your room, so it’s not just the immediate area that benefits.

Will the new Dyson Pure Cool air purifiers clean my air?

We’ll be able to answer this question once we get the test results from our lab in early summer. We test air purifiers’ ability to extract particles of dust, smoke and pollen from the atmosphere inside our test chamber.

The best air purifiers remove more than 90% of the particles we add. Poor machines manage only 44%. The worst remove so few that we can’t officially report on the figure.

We have full test results for Dyson’s previous generation of air purifiers, the Dyson Pure Cool Link TP02 and Dyson Pure Cool Link DP01.

You can find out how they performed in our tough lab tests – go to Dyson air purifier reviews.

Why buy an air purifier?

If you suffer from dust and pollen allergies, a good air purifier can reduce the number of allergens in the air.

We all know the potentially harmful impacts of being exposed to outdoor air pollution, especially if you live in a busy city. Buying a good air purifier is one way of tackling indoor air pollution.

Last spring, we investigated indoor air pollution before and after doing a range of normal household activities in three different types of houses. We did tasks that included cleaning, using air fresheners, lighting candles and even cooking a fry-up and burning toast.

In one case, we found that the particulate matter levels (PM), which can increase the risk of lung and heart disease if at persistently high levels, was increased by over 560 times. Which? members can read our full air pollution investigation.

You can take steps to help reduce PM levels. Use an extractor fan or cooker hood, and open your windows or any trickle vents. Vacuum regularly, preferably with a vac that sucks up dust with minimum emissions – see our Best Buy vacuum cleaners.
