When Dyson upgraded its smart air purifier,fishnet tights, lingerie sex videos the Pure Cool, earlier this year, it went out of its way to make it was less irritating to use in winter months. Since the Pure Cool doubles as a cooling fan, Dyson gave it a backwards-airflow mode that pushes the air out the sides, greatly reducing its "chilling" effect.
So it was probably inevitable that the Dyson Pure Hot+Cool came later. Dyson has had cooling fans that double as space heaters ever since the first Dyson Hot came out in 2011, pairing the company's bladeless Air Multiplier air-blowing tech with, well, heat. I've used the Dyson Hot as a space heater, and it works well, heating up smaller rooms in just a few minutes.

I was a fan of the Pure Cool tower, which seemingly thought of everything that most folks would want in an air purifier, combining that with a well-designed app that captured impressively granular data about the air quality in your house.

Dyson modified the design in ways both obvious and subtle. The end result is still an impressive household appliance that does its job well, though it might not suit everyone's needs.
It certainly won't suit everyone's price range. The Pure Hot+Cool costs $599.99, which is $50 more than the Pure Cool tower. The company offers less expensive versions with fewer features, though they never get cheap per se. This is Dyson, after all.
Hot looks
Original image has been replaced. Credit: Mashable Let's start with the obvious: It's smaller. The Pure Hot+Cool has a smaller "loop" (the hollow oblong part) than the Pure Cool tower, but it's not circular like some of Dyson's other small fans. It definitely looks like what you'd get if a Pure tower and Hot fan had a baby, which is a little on the nose.
While the upper portion is smaller, the base — which houses the air intake, filters, motors, and other components — is bulkier. That makes sense; besides the sophisticated air-filtration system, this model needs to house a heating element as well. It is slightly heavier than the Pure Cool tower, but only by about half a pound.
The heating mechanism requires other modifications, however. Whereas the power cord is removable from the chassis on the Pure Cool, not so on the Pure Hot+Cool, and the cable end is no longer a Dyson-branded adapter but a standard plug. The cable's also gray instead of white.

There's a circular display on the front that can show the current mode, tiny air-quality charts, the temperature and humidity, WiFi connectivity, and more. You toggle through them by pressing the "i" button on the remote, but the app is loaded with more info.

In addition to controls for oscillation, the timer, backward-flow, and night mode (which never raises the fan above level 4), you also get buttons for heating and cooling. In total there are 10 buttons (12 if you count +/- controls separately), which isn't toocrazy, but it's getting borderline for folks who want something that "just works."

What's different, what's missing
Going into this review, I expected to repeat a lot of what i said about the Pure Cool, and that mostly stands. But the Pure Hot+Cool managed to surprise me, and not always for the better.
First, a quick recap of the air filtration tech: Dyson breaks down contaminants into four buckets: The first two tell are microscopic particles, PM2.5 (particles 2.5 microns wide or smaller) and PM10 (~10 microns). The third is VOCs (volatile organic compounds), which are potentially dangerous chemicals like benzene or formaldehyde. Last is nitrogen dioxide (NO2), which can contribute to diseases like asthma.

Credit: Mashable Just like the Pure Cool, you can cycle through the current air quality, with separate screens for all those contaminants, on the front panel, but the data really comes alive in the app. Not only does it show current air quality in a brilliantly color-coded way — contrasting your inside air with the air quality outside — but you can really dive into historical data as the purifier continuously monitors and records the state of your air (you can turn continuous monitoring off if you're not comfortable with this).
Adding the Pure Hot+Cool to the Dyson Link app is easy, and I didn't have as many false starts with the Pure Cool, which seemed to require the app to "forget" the purifier every time I unplugged it at the start (it still saved my data). If you have more than one Dyson Link product, you just swipe from one to the other.
The app also lets you control the Hot+Cool just like the remote does, with one key weakness: You can't adjust the heat. That's a big disappointment since it means you can't warm up a room remotely or even from another room. There's a safety factor here, certainly, but I wish there was a better way to balance it.

There's no actual air conditioning going on, so it's not like it'll freeze things, but it will prevent the purifier from shutting down the fan since it'll never get to the target temperature. But if you want to heat things up, you'll need to go to the room the purifier is in and use the physical remote.
A cosy combo
Original image has been replaced. Credit: Mashable That was pretty much the only issue I had with the Pure Hot+Cool, however, and it's not even that fair a criticism since Dyson was clearly forced to strip those controls due to safety standards. The only other thing to consider when thinking about the Pure Hot+Cool is whether you really want to pay 600 bucks for an air purifier.
Check that. The question is really, do you want to pay 600 bucks for an air purifier anda space heater. Now, you can definitely buy relatively inexpensive versions of both and save a lot. But you'd also need to give up more floor space. There are other purifier/heater combos, but actually not as many as you'd think, and many of those aren't much cheaper than the Dyson.
In other words, the Dyson Pure Hot+Cool may not be the only game in town when it comes to serving the twin needs of air quality and heat, but given everything it does — and the sleek, smart, and singular package it all comes in — the extra expense is an easy thing to warm up to.
Correction 1/9/19:An earlier version of this article identified the product as the "Dyson Pure Hot+Cool Link," but that is actually the name of the previous version of the product.
