SELLING: Dyson air purifier with 21 months warranty left. I bought it 3 months ago, this air purifier has been working wonderfully. Since I’m moving out of New York City, I’m selling this air purifier. This Dyson HP02 air purifier has heating function, so you don’t even need air conditioner in the winter, and it can connect with your cell phone to monitor indoor air quality. I bought it from Dyson website for $650, now selling for $379. Let me know if you are interested!
