Dyson HP09 Purifier Hot & Cool Formaldehyde

We test beyond the industry standard. For real living spaces. Dyson engineers designed the POLAR test to challenge the industry standard test methods - measuring purification, sensing, and circulation to ensure the whole room is purified properly. Graphic comparison of CADR test v Dyson test Some CADR methods do not measure purification performance in a realistically-sized room. In this 28.5m³ room, one fan mixes the air before the test, and another circulates air during the test. Only one sensor measures air quality. Graphic comparison of CADR test v Dyson test Dyson's POLAR test goes further to measure purification throughout a realistically-sized room. In this 81m³ room, there are no fans except the air purifier with nine different sensors to measure even-room air quality. Pollutant sources in a living space and kitchen Poor air quality isn't just a problem outside. It's a problem inside too. From pets and flowers, to sprays and stoves, our homes can trap pollutants in the air. That's why Dyson purifiers automatically sense and remove them. Common household pollutants Pollen particle Common allergens - pet dander, pollen and dust PM10 Bacteria Bacteria and mold spores PM5.0 Particulate emissions Industrial emissions and smoke PM2.5 Ultrafine particulate emissions Ultrafine particles PM0.1 Formaldehyde molecule Formaldehyde (HCHO) Carpets, rugs, and flooring Odour particles Odors Household fumes and cooking Benzene molecule Benzene and VOCs Cleaning products and candles Nitrogen dioxide molecule Nitrogen dioxide Gas stoves and car exhausts Internal sensing technology and LCD screen showing formaldehyde detected Senses and reports, automatically Four sensors, including a solid-state formaldehyde sensor, interact with our unique algorithm to precisely diagnose, display and react to your air quality. Graphic of Dyson filtration system Graphic of Dyson filtration system Captures and destroys with advanced HEPA filtration The HEPA+Carbon filter captures gases and 99.97% of particles as small as 0.3 microns. Our catalytic filter continuously destroys formaldehyde. Air purifier catalytic tunnel Destroys formaldehyde¹ in billions of catalytic tunnels Dyson's unique catalytic filter continuously traps and converts formaldehyde into water and CO₂. And it self-regenerates, so it never needs replacing.¹ Fully sealed air purifier Fully sealed to HEPA H13 standard To prevent pollutants from leaking back into the air, it's not just the filter that's sealed to HEPA H13 standard, it's the whole purifier.³ So what goes inside, stays inside. Man controlling Dyson Purifier with Dyson Link app Smart purification, controlled by app or voice Control and monitor air quality from anywhere with the Dyson Link app, or hands-free with compatible voice services. Features Image showing powerful, cooling airflow Cools you when needed Projects over 77 gallons of air a second for cooling airflow. Someone changing their filter Heats when needed Air Multiplier™ technology projects purified, heated air throughout the room.² Once your target temperature is reached, heating automatically stops. Purified air exiting the back of the purifier Backward airflow. Purifies without cooling you. Airflow is diverted through the back of the machine, maintaining effective purification without cooling you.⁴ Someone changing their filter Easy filter care The catalytic filter never needs to be replaced. We recommend replacing the HEPA+Carbon filter when you're alerted by the Dyson Link 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.
