Dyson is known for two things: Elegant technology and high prices. The company takes mundane objects like vacuum cleaners and fans, and remakes them into stylish paragons of their respective categories, superlative in both form and function. It then attaches price tags to those objects that are often several times more than similar items on the market – and that’s certainly the case with the Dyson Cool AM06. This desk fan is £250, with larger models reaching up to near the £400 mark. It's the follow-up to Dyson's Air Multiplier fans, and like all other Dyson products it's remarkably elegant and effective even considering its extravagant cost.
How it works
The Dyson Cool series looks almost exactly like the Dyson Air Multiplier line. The AM06 model is a tall desk fan that looks like a magnifying glass for a giant. A cylindrical base holds up the large hoop that serves as the fan's head. Nothing visibly moves, but air goes out. In the words of Bill O'Reilly, you can't explain that. So I will explain that.
A brushless motor sucks air in through a grille around the base and circulates it around the inside of the hoop on the top. The air comes out of a slit along the inside of the hoop, and flows along its airplane-wing-shaped cross-section to blow out onto the user. According to Dyson, this airflow brings in the surrounding air and pushes it through the hoop as well, multiplying the amount of air the fan moves compared to how much it takes in (hence the original Dyson fan's Air Multiplier name).
The hoop itself has no moving parts; you can actually take the head off and see the enclosed motor in the base that pushes air up through it. Instead, the hoop is only used as a guide for the air, circulating it smoothly and more efficiently in comparison to an exposed motor with fan blades. The base actually uses a form of conventional fan to push the air through, but since the blades aren't exposed and the air is circulated through the hoop, the resulting airflow is quieter, produces less buffeting, and is more efficient.
The design is also much easier to clean, with no exposed fan blades to collect dust and only a few smooth surfaces to wipe down if dust accumulates.
The fan is available in three two-tone versions with a different colour for the base and the hoop: Iron/blue, black/nickel, and white/silver. The version we tested was black/nickel. The base has a 150mm diameter and it’s 190mm high where it meets the hoop, which itself has a 300mm diameter and is 100mm thick with its axis perpendicular to the base's. The front of the base holds a single power button and a two-digit LED display that shows the fan's setting, and also if you've set a timer on it. The whole fan weighs approximately 1.8kg and stands 460mm tall.
To actually control the fan, you need to use the included remote. It's an 80mm long, slightly curved stick shaped like a disposable lighter, with Power, Rotate, Fan Setting Up/Down, and Timer Up/Down buttons. The remote makes it very easy to turn the fan on and off, set a timer for it to turn off automatically, adjust the power level from 1 to 10, and toggle a back-and-forth rotation.
The fan can gently rotate back and forth with the push of a button on the remote. It pivots on a very short base separate from the rest of the body that lets the entire fan move. You can also manually pivot the fan up or down on a curved hinge above the display. It can tilt about 10 degrees up or down, but since the head puts out such a large cylinder of air that should be enough for most desk or table adjustments.
The Dyson Cool seems to do its job admirably. For its small size, it puts out a good amount of air that indeed doesn't buffet or feel choppy in any way. It's a smooth breeze that can actually feel quite refreshing, even at maximum power. It creates a cylinder of air slightly larger than the 300mm hoop of the fan itself, and at full power it can be felt about ten feet away. The airflow is directed enough, and the fan's head is high enough that it won't blow papers all over your desk.
Dyson claims that the Cool is 75 per cent quieter than the Air Multiplier. We haven't tested the Air Multiplier for comparison, but the fan is certainly impressively quiet at most levels. At maximum, it makes a high-frequency hum one would expect from a powerful fan, but at half-power it barely registers as white noise while still producing a pleasant breeze.
This isn’t an easy review to score. Objectively, this is an excellent device. It's a quiet, powerful, elegantly designed fan that represents the apex of style and function for desk fans. It's also £250, and that's for the small AM06 model.
Ultimately, the question regarding the Dyson Cool is not "is it good," because it clearly is. The real question is: "Is it worth it for you?" If you can justify spending £250 on a desk fan, there's no question that the AM06 is a fantastic choice. If you can't imagine spending more than two digits on a fan, then its quality is moot. Regardless, it's an impressive and attractive desk fan I'd be happy to keep on my desk when the office heats up.
