Through the unique algorithm of Dyson Purifier Cool Formaldehyde Air Purifier, TP09 integrated sensors constantly analyze air & cross-checks data every second. LCD displays results of pollutants at a molecular level Removes odors and gases including VOCs with a layer of activated carbon while the HEPA filter captures 99.97% of particles 0.3 microns in size Purified air is projected throughout the room as Air Multiplier™ technology generates the circulation power to draw even distant pollutants into the machine Continuously traps and breaks down formaldehyde molecules¹ into water and CO₂ thanks to its Dyson catalytic filter. Maintain precision for the lifetime of the machine as it features solid-state sensor to detect formaldehyde molecules 500 times smaller than 0.3 microns. The whole machine meets HEPA H13 standard. Air purifierr cools you down when desired as it projects over 77 gallons of air a second for cooling airflow. To purify, without cooling you the air purifier diverts airflow through the back of the machine 20% quieter from it's previous model as it is acoustically engineered to reduce turbulence With a dimmed display this air purifier monitors and purifies using the quietest settings for light sleepers You get purified air around the whole room with adjustable oscillation of up to 350 ̊ With automatic filter-life notifications on the LCD or Dyson Link app you can quickly & easily change the filter Store the remote neatly on top of the machine thanks to its curved and magnetized design With Dyson Link app you can control and monitor your air quality from anywhere.
