The Dyson Pure Cool - purifying tower fan, is the only purifying fan to clean a whole room properly. We design our purifying fans to go beyond test chamber conditions and focus on real home conditions - this is more than just having an efficient filter. Dyson engineers and research concluded that to clean an entire room properly, you need to sense pollution events automatically; capture ultrafine pollutants; and project cleaner air around the room using Air Multiplier technology. Only the Dyson purifying fan is designed and tested to do all of this. Features: Intelligently purifies and cools you. Dyson technology helps create a cleaner, healthier home - Our vacuums and purifiers are scientifically proven to capture particles as small as allergens and bacteria. 360° filtration system uses activated carbon to remove gases and odors and a HEPA filter to capture 99.97% pollutants as small as 0.3 microns.
