This Dyson Pure Cool Me in gunmetal/copper cools you and purifies the air you breathe. Enjoy clean air with Dyson's first personal purifying fan thanks to Dysons Core Flow technology that guides powerful jets of air across the dome at high velocity where they converge and project purified air. Precisely control the airflow by adjusting the dome's position, where you can angle the flow higher or lower. This purifying fan's sealed filter and it's HEPA filter automatically captures 99.97% of pollutants and gases as well as allergens as small as 0.3 microns from the air, making it the ideal situation for allergy sufferers and improving air quality around your home. Enjoy a comfortable night's sleep and keep cool at the same time by setting the timer anywhere between 15 minutes and nine hours.
