Why I like it: In ultrahigh-end tower fans, Dyson is awfully tough to beat. Its latest, the Dyson TP07, is a behemoth with king-size activated carbon and glass HEPA air filters hugging the base intake. That allows it to purify the air it puts out, removing things like dust and allergens from the air you breathe. Dyson claims it can catch particles as small as 0.3 microns wide. You don't have to spend that much on every air purifier but if you want a combo option this is the elite choice. The Dyson also boasts 10-speed settings ranging from an ultraquiet 28 decibels up to a 48-decibel blast of concentrated air. It was the most comfortable tower fan I tested, too, with a cool, steady stream of air that feels like a much less forceful version of one of Dyson's bathroom hand dryers. An LCD screen on the front of the device tracks air quality in real time but you can also set it to display things like the ambient room temperature or the relative humidity. You can also customize the oscillation angle between 45-, 90-, 180- and 350-degree settings, which is a nice, unique touch. The sleek remote control docks magnetically on top of the fan when you aren't using it. On top of all of that, the TP07 features app-enabled smarts. I'll admit I didn't spend too much time testing all of the features but the app offers a detailed look at the air quality in your home and it lets you create custom cooling schedules too. You can also use it to customize the fan's autopilot mode to your liking. The TP07 also supports voice control via Alexa or Siri. The one big downside? Dyson is infamously expensive and to get the very best you'll have to pay more than $600. That's too much for many people unless you're looking into a serious upgrade. Who is this for: Buyers without budget limitations who want a tower fan that does everything and does it well. Who shouldn’t buy it: Anyone who wants to keep the fan cost within reasonable levels.
