Always ahead of the curve—usually by a lot, Dyson has nailed it again with its Pure Humidify Plus Cool, a cutting-edge home appliance that is an air purifier, humidifier, and fan in one. On top of that, it works with Siri & Alexa and even cleans itself. For purification, it uses HEPA and activated carbon filters to remove 99.9% of bacteria in the water and the air. It is just over 3-feet tall and offers adjustable timer, a 1-gallon water tank, & will humidify the air for 36 continuous hours.
