The Dyson Pure HotCool adds heating to air purification

Dyson launched a big upgrade to its air purifier earlier this year with the Dyson Pure Cool.

The UK-based company is now launching a new version called the the Pure Hot+Cool. As you might suspect, it's the same general idea, only this time the purifier can heat the air as well as cool it.

The oval on top of the base pushes the air outward via Dyson's Air Multiplier tech (used on all the company's fans, heaters, and air purifiers).
