Dyson's latest purifiers combine intelligent sensing with an advanced filtration system. Three phases of purification sit within a fully sealed filtration and airflow system. So what goes inside, stays inside. A solid-state formaldehyde sensor and a unique catalytic filter detect and continuously destroy formaldehyde. Then powerful Air Multiplier(TM) technology purifies, heats the whole room and cools you. Third party full machine testing based on GB/T 18801 - 2018 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice. In maximum setting. Tested for air projection (DTM801), purification coverage in a 2860 ft 3 room (TM - 003711), and heating performance in a 1236 ft 3 room (DTM961).

• Cools you when needed: Projects over 77 gallons of air a second for cooling airflow
• Heats when needed: Air Multiplier technology projects purified, heated air throughout the room. Once your target temperature is reached, heating automatically stops
• Backward airflow, Purifies without cooling you: Airflow is diverted through the back of the machine, maintaining effective purification without cooling you
• Easy filter care: The catalytic filter never needs to be replaced. We recommend replacing the HEPA filter when you're alerted by the MyDyson app or every 12 months, whichever comes first
• Night mode: For lighter sleepers, it monitors and purifies using the quietest settings along with a dimmed display
• Remote: Curved and magnetized to store neatly on top of the machine
• Control air quality, wherever you are: Control your air purifier from anywhere with your smart device, whether you're traveling, at work, or simply at home on the sofa
• Monitor air quality. View reports, fast: Monitor indoor and outdoor air quality from your smart device. See your machine's activity as well as temperature, humidity, and filter reports
• Oscillates up to 350: Adjustable oscillation projects purified air around the whole room
• Senses and reports, automatically: Integrated sensors constantly analyze your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD
• Captures gases and ultrafine particles: The HEPA filter captures 99.97% of particles 0.3 microns in size. A layer of activated carbon also removes odors and gases including VOCs
• Automated filter alert
