Poor air quality isn't just a problem outside. It's a problem inside too. The Dyson Purifier Hot+Cool Gen1 machine purifying fan automatically senses, captures and traps pollutants to purify your whole room.

It heats or cools the air, while removing 99.95% of particles as small as 0.1 microns. From pets and flowers, to sprays and stoves, your home can trap pollutants in the air. Dyson purifiers remove them.

The Dyson Purifier Hot+Cool Gen1 machine purifying fan captures common household pollutants include pet dander, pollen and dust, industrial emissions, nitrogen dioxide from gas stoves and car exhausts, and benzene and VOCs from cleaning products and candles. We test our purifiers in a room size of 81m³, with sensors that continuously measure air quality, filtration, sensing and circulation - to ensure the whole room is purified properly. Only Dyson purifiers have Air Multiplier technology to draw in distant pollutants and project 290 litres of air per second throughout the room.

There are not one but two filtration phases. The 360 degree sealed filter system combines a HEPA and activated carbon filter to remove microscopic allergens and pollutants. And it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier.

So what goes inside, stays inside. In the box: Dyson Purifier Hot+Cool Gen1 machine, Remote control, 360 degree glass HEPA and activated carbon filter.
