Arguably the best small heater fan available, Dyson's newest innovation is powerful and very beautiful – but comes with a hefty price tag

expensive; noisy enough to drown out a TV at full blast; can only push warm air around

This smart fan will delight gadget-lovers and hypochondriacs alike

Efficient, quiet fanning, Air purifying is a nice touch, Dyson Link app is great

No Apple HomeKit or Amazon Alexa support, You'll be gasping for air when you see the price

Unless you're the most devoted Dyson loyalist, you'll find much better values if you shop around -- including Dyson's own AM05.

The Dyson AM09 Hot+Cool performed very well in our tests; and offers a distinctive; functional; feature-rich design

Though very solid, the AM09 doesn't outperform much cheaper competitors by a wide enough margin to justify the price difference; If you misplace the remote, you'll be unable to access common controls like oscillation and the sleep timer
