Dyson HP00 Pure Hot+Cool Air Purifier

This Dyson Pure Hot+Cool is a heater, fan and air purifier all in one. The triple function means its useful all year round. It catches particles in the air using the 360 degree Glass HEPA filter, which can filter out particles as small as 0.1 microns - if youre not a scientist, that means things 100 times smaller than a human hair. With the Air Multiplier technology, youll get an uninterrupted stream of purified air so you can breathe easy.
