Does exactly what it is meant to with reliability and efficiency

I like it when i sync it to my Alexa and sit back and relax

I purchased the Dyson hot and cold fan 6 mths ago. So far I love the cools you down without blowing you away. I cant wait for winter to try out heater part

I brought this heater over 12 months ago and cannot fault it. We use it all year round for heating and cooling and is so convenient that we can control it using our iPhones from the lounge. It is more efficient that our split system so use it instead on most nights.

I’m not one for insincere reviews - and genuinely find reading them helpful in deciding weather I will buy a product or not! Honestly; although this is now the older model - I couldn’t rave about it more (I can’t imagine how incredible the newest model must be!!) The sheer thought and technology they have put into creating this machine is extremely impressive! I purchased this product to keep our baby safe throughout winter with clean, warm air (I dislike the thought of using a rental property air conditioner immensely) and wow. I love going into her room now because it is just so comfortable and clean. She seems to sleep better now too, which I love. Her bedroom is on the small side, so it works perfectly for the space. I hope this is helpful for someone :)

The three functions of heating, cooling and purifying work brilliantly. The app is super great too and I love being able to control all of the setting from my bed via my phone. The other fab feature is the magnetic remote that sticks to the curved top of the machine. I really love this machine and I am sleeping so much better at night now I have it. My only criticism is that it should be taller so that you can be in bed with it placed on the floor and the cool air be of a height to reach you. With the current design I have to place it on a small side table to be high enough to reach me in bed. I think it’s pretty quiet too. Also love the night mode so it gets rid of the annoying LED display when you are sleeping. So many great design features, it’s really been well thought through and is a great product.

Reviewing the Pure Hot + Cool is a bit of a fan-kless task. Even when you account for its internet connected smarts and sophisticated air filtration, it’s not a particularly complex product to use. You just turn it on and it works. Bosh! If you’ve got the cash and are thinking of buying one of these, that’s probably what you wanted to hear. There are enough gadgets in the world already that constantly nag for your attention. Ultimately, this one just makes sure the temperature in your home is alright and the air you’re breathing isn’t full of nasty guff. And if you want to tweak this arrangement, you can do so from the palm of your hand. In short: fan-omenal stuff. Buy the Dyson Pure Hot + Cool here from Argos

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;

Aside from the obvious £499.99 pricing constraints, Dyson’s Pure Hot+Cool fan is a strong performer that not only handles its dual heating and cooling capabilities with ease, but the feature-packed device is a welcome addition to the home of anyone concerned about the health and wellbeing, giving you real-time information on the nasties that may be filling up your lungs as you breathe. The device’s considered design works with most interiors - we can’t imagine anyone thinking it’s ugly. Despite being completely plastic, the build quality is also top notch, just as we’ve come to expect from the brand. It might not be for everyone, but this powerful heating and cooling device really does fulfil its cleans, working better than we initially expected, and will most definitely satisfy the temperature demands of users all year round. Well done Dyson.

Exceptional design and build quality; Can be used year-round; Speedy purification reactions ; Great app and features;

Pricey; Slight latency when altering settings;

Bought for over a month now, didn’t notice any changes with my asthma/allergic rhinitis (aka hayfever) but works well as a heater in a small space. Cooling is alright but you’d still need air conditioning.
