Although cheaper than the other Dyson fan heaters, which double up as purifiers and can be controlled via a smart app, the Dyson Hot+Cool Jet Focus AM09 is still considerably more expensive than the competition. The Dyson Hot+Cool Jet Focus AM09 is an undeniably good-looking piece of kit, and the simple remote operation and quiet fan operation make this a great choice for those that want heat in the cold months and cold air in the warm months. On maximum speed, the fan can push air at 5m/s at 15cm away, making it one of the most powerful fan heaters, or indeed fans: that level of air flow is enough to help cool you when it’s hot weather.
