  • Automatically senses, captures, and traps 99.97% of particles as small as 0.3 microns
  • Detects airborne particles, gases, and volatile organic compounds like NO2, using an infrared laser to measure particles in the air
  • Electrochemical cell detects formaldehyde while the non-replaceable catalytic filter traps it in tunnels, breaking it down into water and CO2
  • Monitors relative humidity and temperature levels in the room to help you stay comfortable
  • HEPA H13 and activated carbon filtration effectively remove gasses and particle pollution
  • Air Multiplier technology generates circulation power so the entire room is purified
  • Fully sealed airflow and filtration system traps pollutants so they don't get back out into your space
  • Long-range projection heats your room evenly while a powerful stream of purified air can help keep you cool
  • Airflow is diverted through the back of the machine so it doesn't have to blow on you while it purifies
  • Adjustable 350-degree oscillation delivers purified air to every corner of the room
  • Quiet settings and a dimmed display won't disturb you as you read, watch TV, or sleep
  • Controls include on/off, info, oscillation, fan/purifier modes, sleep mode, and fan speed controls of 1-10 for customized comfort
  • Dyson purifiers capture COVID-19 virus

Please note:

  • Third party full machine testing based on GB/T 18801-2015 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
  • Dyson purifiers were challenged with airborne SARS-CoV-2 (the virus that causes COVID-19) at an independent lab, using a 0.37 m3 chamber for 90 seconds. Dyson Purifiers were also challenged with Phi-6 bacteriophage (a surrogate to test SARS-CoV-2) at an independent lab, using a 30 m3 chamber. After 90 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99.9 %. Real-life efficacy may vary.
