The Dyson Purifier Hot+Cool HP11 automatically detects airborne pollutants and recirculates cleaner air while heating or cooling the whole room, backed by fully sealed HEPA H13 filtration. It’s built to work quietly in the background all year, switching between heating, cooling and pure fan modes as the seasons change.
Key features
- HEPA H13 filtration — captures 99.95% of particles as small as 0.1 microns, along with allergens, dust and gases, in a fully sealed system so nothing escapes back into the room.
- Automatic detection — onboard sensors continuously read the air and adjust purification without needing to be told to.
- Heats and cools — Air Multiplier technology delivers up to 290 L/s of airflow, projecting warm air evenly in winter and a cooling breeze in summer.
- MyDyson app — remote control, live air quality reports and scheduling from a smartphone, with hands-free control via compatible voice assistants.
- Whole-room oscillation — the machine spreads purified air around the room rather than in a single narrow stream.
- Simple maintenance — a single combined HEPA and carbon filter cartridge handles all filtration stages.
