Dyson HP09 Hot+Cool Air Purifier with HEPA & Formaldehyde Filters - White

• 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, as well as wildfire smoke (based on capture of particles, ammonia, benzene, and acetic acid)

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.
