Dyson Pure Cool™ purifying fan (White/Silver)

The only purifying fan to clean a whole room properly.

We design our purifying fans to go beyond test chamber conditions and focus on real home conditions – this is more than just having an efficient filter.¹ Dyson engineers and research concluded that to clean an entire room properly, you need to sense pollution events automatically, capture ultrafine pollutants and project cleaner air around the room using Air Multiplier™ technology. Only the Dyson purifying fan is designed and tested to do all of this.²

Wonderful NEW Dyson Air Cleaner


I'm using this new air cleaner now for about a month. It's fantastic and much more innovative than the previous models. You can control it either by its own remote control or over the cell phone app. It detects practically immediately any kind of pollution (cigarette smoke, car exhaust gas, increased air dust, and so on.....) and starts running, until the air is clean again. The graphic display shows a lot of air related features, like ambient air temperature, humidity, and what kind of pollution it is "fighting" against. I highly recommend this product, a well designed and typical (Dyson) innovation.
