Dyson debuts a heater-fan-purifier triple threat

If you have poor air quality in your home, no central heat or air conditioning, and an extra few hundred dollars, your day is about to get much better.  Dyson has come out with the Pure Hot + Cool Link, which combines a heater, fan and air purifier all into one $599.99 package. The announcement comes just a few months after they released their Pure Cool Link, which doesn't come with the heater. The new Pure arrives in stories on Sept. 6.  SEE ALSO: 10 Gadgets for Your High-Tech Home Bu
