Dyson are offering $200 off their HP00 Hot+Cool Purifier.
Dyson Pure Hot+Cool - $499
Good Guys, JB, Bing Lee, Myer, etc. have priced to match if you prefer a different store.
You can get an extra 5% off via the Dyson eBay store for $474.05 with eBay Plus code PLUSMAR1
They also have the HP03 'Link' model on sale for $599. Only difference I can tell between them is the HP03 has Wi-Fi for remote control via the Dyson app.
Dyson Pure Hot+Cool Link - $599
Anyone comment on how these are compared to normal fans or Vornado units for cooling?
