Overview
Dyson built this purifier around cone aerodynamics that send a focused jet of clean air across a large room. A big sealed HEPA filter traps fine particles and gases, and a catalytic stage breaks down formaldehyde.
Large-room coverage, low noise and a filter that lasts years make it a low-upkeep choice for big spaces. Its height and weight mean it is not easy to move between rooms.
Who it's for
Owners of big living spaces, studios or offices get long-throw airflow with a long-life filter. People needing a light, portable unit for small rooms should look at smaller models.
Pros and cons
- Long-throw airflow for big rooms
- Filter lasts years
- Quiet do not disturb mode
- App and remote control
- Heavy and tall
- App needs Bluetooth and Wi-Fi device
- Floor area not stated
Performance notes
Even purification in a large space depends on mixing the air, which the projected jet does by reaching far corners. The large filter area slows clogging, so it lasts longer between changes. Formaldehyde is broken down rather than just trapped, so it does not re-release.
