Game changer


Having been an ardent buyer of Dyson products for more years than I care to remember, I was very excited to try the Dyson Pure Hot + Cool Gen 1 Purifier. I have not been disappointed. The recent heatwave has been challenging for all of us and I didn’t expect this machine to make quite the difference that it has. My husband and I slept soundly for the first time in days and I love the fact that it is purifying the air that we’re breathing at the same time as cooling us down. We have had it alongside us in the evening downstairs as well and I enjoy checking the LCD screen to see just how pure the air is! In the Winter we should be able to use the purifier to heat whichever room we are in so we can avoid heating the whole house. The combination of both hot and cold air, alongside the air purifying capabilities, make this machine a total winner in my eyes. I would definitely recommend it and will be buying another one for my son whose little boy suffers from breathing difficulties.

Frequently asked questions

What is different about the Dyson Purifier Hot+Cool™ Gen1 machine?

The Dyson Purifier Hot+Cool™ Gen1 machine has the same core capabilities found in our purification products. The Dyson Purifer Hot+Cool™ Gen1 machine, senses pollutants PM2.5 and PM10 - filtering all pollutants except formaldehyde. Although this machine doesn’t have app connectivity, the remote control allows you to easily adjust settings on the machine.

What is new about the Dyson Purifier range and how is it different to other purifiers?

Dyson engineers are perfectionists. Channelling our relentless dissatisfaction, we have re-engineered the Dyson Purifier range to be our first purifiers fully sealed to HEPA H13 standard. Capturing 99.95% of ultrafine particles and preventing pollutants from leaking back into the air you breathe.⁴

How often should I replace my filter?

We recommend replacing the HEPA+Carbon filter every 12 months.⁵ That's because over time, filters can get clogged with pollutants, and even let unpleasant odours back into the room. The machine will alert you when it’s time to change filters. A filter life reading can be found on the LCD screen. The catalytic filter never needs replacing.
