Dyson Pure Cool™ DP04 purifying fan (Iron/Blue)

The only purifying desk fan to clean a whole room properly.

"Watch video"

We design our purifying desk 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 desk fan is designed and tested to do all of this.²

Very intelligent product

Kcs8605

I have a household with 3 cats, and after we got the cats we found out my husband and 2 children were allergic to cats, so we have HEPA filters all over the house. This purifier is by far the most intelligent filter we have (and we also have the Dyson Pure Hot+Cool Link Purifier). It automatically detects when there is a lot of pollutants in the air and turns on and filters accordingly. The display is a nice feature so I can tell when the air quality is poor in the room. I am always cold, so I love the fact that there is an option to switch the air flow to avoid cooling the room even more. My husband has totally taken over this fan, though, because he loves a cool room when he sleeps, but needs a filter to purify the air. The purifier is quiet enough to not disturb our sleep while keeping him cool. It was so easy to set up the product. We did have a slight issue setting up the filter on our Dyson app, but it was an easy fix with the support we found on Dyson.com and we were able to set up the product within about 10 minutes on the app.
