Triple function Dyson Pure Cool & Hot Air Purifier, gently used 1 season, works fantasticly. Two remote controls. Current filter has about 1/2 life cycle left. Paid $599. Dyson claims it removes 99.97% of pollutants and allergens as small as 0.3 microns and I can believe it was it was a lifesaver for us. We are moving and can´t take it with.
