Our Verdict

Dyson PH04

Blueair DreamWell

The Dyson PH04 is better than the Blueair DreamWell. Like the Blueair, it's an evaporative humidifier, but the Dyson also doubles as an air purifier. It raises humidity faster and is much easier to clean, making it a more capable option if you want stronger humidification and air filtration from one device. The Blueair DreamWell is much easier to fit into a smaller room, though, as the Dyson is exceptionally large, and it's quieter at its highest setting and more energy efficient as a humidifier. It also has a dedicated aroma stone for essential oils, which the Dyson lacks.
