The Dyson Purifier Cool Autoreact™ TP7A Purifying Fan automatically senses, captures and traps pollutants for cleaner air.   The Dyson Purifier Cool Autoreact™ TP7A Purifying Fan combines intelligent sensing and an advanced filtration system, to purify and cool the room. The activated carbon filter removes gases and odors, and a HEPA filter captures ultra-small pollutants.   Features/Benefits: HEPA filter removes 99.97% of particles 0.3 microns in size Automatically purifies and cools you. 360° filtration system uses activated carbon to remove gases and odors and a HEPA filter to capture 99.97% of particles 0.3 microns in size. The purifier is fully sealed, so what goes inside stays inside. Two phases of purification sit within our fully sealed filtration and airflow system. Air Multiplier™ technology generates the circulation power to draw distant pollutants into the machine, projecting purified air throughout the whole room.
