A great fan, an unreliable heater

I’ve had the Hot+Cool HP01 for about 2 years now and from week one it had intermittent issues where it would display error code H2, stop heating and wind up the fan as if it

Heats up a room in no time in the cold weather. I’m saving money on heating bills by not having to keep raising the thermostat higher and higher. In the summer, when I need
it cooler and the air conditioner isn’t enough to get the room comfortable, this machine helps cool the room. It is very sensitive in detecting all kinds of allergens and
impurities in the air. It purifies the air within minutes. I live in NYC and this is a Godsend to help with outside exhaust fumes and other smells. I bought it for my asthma. Best
purchase I ever made. It’s worth every dollar.

The Dyson HP01 was easy to setup. It runs quiet and is very effective on both the cooling and the heating side. The small footprint is a real plus and we love the remote
control.We bought this item primarily to warm our theater space in the basement during cold snaps--which it does very well. A side benefit is the fact that it works as a great
fan in other locations in our house when temperatures rise. This has enabled us to reduce dependence on AC on hot days. In fact, this is where we get the most bang for the
buck.Absolutely love it.

If this is the case it is an extreamly poor design because no other appliances seem to be impacted by the fluctuation and it renders the heating function useless as a reliable heat source. While the fan design is nice, and the air filter is appreciated, I would recommend saving your money on the heating option and simply pair the fan with a reliable radiator style heater. I would like to rate the fan and air purifier higher than a 1 star, but I think people are to complacent about giving mediocre reviews to products that do not fulfill the function advertised especially from a company that demands a premium for allegedly superior products . Had I known what I know now, I would have made a different purchasing decision.

Mixed feelings about this product. There's a good amount of adjustability with both the air speed and direction. It takes up less space than a conventional fan and is comparatively quiet at lower fan speeds. Looks and feels like a quality product, and the remote being shaped to sit on top magnetically is a great feature. The filtering effect does remove pollen from the room which was my main reason for purchasing the purifying model. Being a heater as well makes it useable for the whole year and a little better value for money than the 'Cool' alone. However, there's no air conditioning so it can't cool a room which is a shame. The remote is also very delicate and easily damaged if it gets knocked from the top. And it's difficult to manoeuvre being quite heavy with ... MoreMixed feelings about this product.

The remote is also very delicate and easily damaged if it gets knocked from the top. And it's difficult to manoeuvre being quite heavy with no hand-holds. But the biggest problem for me is that the VOC & NO2 sensors don't work - I've tried resetting the machine, and unplugging it, and leaving it running for several hours but still no change. Dyson's email customer service is very poor and ultimately told me to phone which I can't do. So overall it does the job I bought it for, but improvements could be made in a few areas.

I purchased the HP02 Hot + Cool unit in 2019 and it started having issues before it was 2 years old (while it was still in warranty). It started showing error code "E" on the display on the machine and the app showed "fault detected" and would no longer control the unit. Whenever that happened, it would blow cold air, but would no longer heat.I brought the unit to the repair center 3 separate times and they could never isolate the problem. Instead, they had me buy new $70 filters to try to correct it. The filters never fixed it, and now that it's out of warranty, it completely stopped working and smelled like it was burning up.

Terrible value for the extremely high price.

I wanted to wait awhile before foing a review to see how well this worked as a room space heater. I can say it works amazingly well. We live in a drafty apartment in the midwest so when we had the bomb cyclone before Christmas this cleaned our air and heated our living room so comfortably well. I didn’t have to adjust the fan above the 5 level. I just set the temp. I want and let it go. Amazing no indoor icicles on the window or in the “fireplace”. I never worried about over heating since it auto shuts of the heat part when temperature is reached. That said it is well worth purchase price as it does a good job purifying our air too. I’ve had less dust to deal with. I really love that it has a timer. I never have to worry about it and thats why I buy Dyson.

This is an excellent purifier with a great filter. I noticed a huge difference in my allergies within 24 hours of purchase.

First of all, it's not meant as an AC - this goes for their entire line of purifiers. All it takes is to read the name of the 500 dollar product you are purchasing - "Purifier, heater, and fan - iron/silver" - see?

If you want it to keep blowing out hot air, you just have to increase the temperature to something higher than your current room temperature. Again, this isn't rocket science folks - when it's 74 degrees in your room, putting the heater on 75 isn't going to make it blow hot air for 5 hours. You can see whether the air is actually being heated by the red dot next to the temperature. Once it hits that temperature, the red dot will turn white. This means it's maintaining that temperature, not blowing hot air.These are very basic uses of the product, and since it seems many reviewers here can't read a manual for a product they paid 500 dollars for - I don't really know what kind of product would make them happy.The fan is far superior to any blade fan I've used, the heat is soft and won't burn you - but it will heat up a medium sized room within 5 minutes. The purifier filter was working well since the first day I used it.

Where do I start?Right to begin with the app, it's easy to set up only asks for minimal information, name, email etc. I used my cheap unbranded android phone and had no problems setting up the app, it took me less than five minutes, after which I received an immediate confirmation via email of my guarantee registered with Dyson; this is a nice touch.The app displays information in a easy to read format, you can control the machine from your phone. I have set up this device in my living room, from my bed on a cold morning I can see the temperature in the living room and I can then turn on the air heater, which is awesome as I have four kids that always complain of the living room being too cold (I have no gas fire and the central heater in the living room is ...

I have set up this device in my living room, from my bed on a cold morning I can see the temperature in the living room and I can then turn on the air heater, which is awesome as I have four kids that always complain of the living room being too cold (I have no gas fire and the central heater in the living room is always the last one to heat up).The air purifier is not a gimmick, it really works, I tested this feature by turning on my electric bakhoor burner (Arabian scented wood chips) the air purifier registered the smoke immediately, the chart displays went red and the fan started to draw the smoke to itself. Need to test the air purifier after a takeaway, we eat pizza in the living room on a Sunday if it can eliminate the pizza smells than this feature really is something special.There is a nice screen on the device which displays quite a lot of information regarding air quality levels, all the different types of air pollutants, I have set mine to show the room temperature which again is neat feature as it eliminates the need for a room thermostat.I bought the original Dyson hot and cold fan (non air purifier) and this latest hot and cold purifier absolutely dwarfs it, this new device is massive compared to it, and I like it!!! as this oversized design really does give it that wow factor in your room; especially in a minimal featured designed house.These are some of the drawbacks in my opinion that Dyson can possibly improve on in future designs: Dyson needs to introduce a removable power cable, I always go overboard with cable management (securing and hiding all my cables) I then can't move my Dysons fans anywhere in the house without untying everything, also with this new device you have the ability to place the fan in the middle of the room and oscillate 350 however the cable is too short to reach the nearest wall, both of these problems could be eliminated if you could buy your own removable cords in any size making this fan truly mobile.I also feel that Dyson should have added a clock to this fans information screen as well as the app, on the app you can set up a time schedule for the device to come on however without a clock on the app you can only use the clock on your phone; which is always a few minutes out, if Dyson had an inbuilt clock on the app this way you would always know precisely what time the fan was turning on and off.The last drawback is the filters, I know we all without consideration replace our car filters for every service, and having something that not only cleans the air in your house, shows live information and also displays when the filters need to be replaced is awesome, I still feel that Dyson being true pioneers should find a way to make these filters washable, afterall they did get rid of the vacuum bag!Overall this device is a real quality product, supported by a user friendly app, I can't believe someone reviewed this device and wanted the price down to £150!!! Just the art like design and quality of this device itself makes it look twice that price, and then consider all of the features of this device and the excellent Dyson support team you get; you can't get that deal for £150, trust me, I would know, I'm a Yorkshire man!

I purchased a Dyson Pure Cool in December 2019. In general, I liked how the unit worked - it was quiet and seemed to do a decent job purifying the air in my living room. It also looks nice, it is sleek and has a nice design. Unfortunately, the unit stopped working in February 2022 (after approximately 25 months, 1 month after the warranty ended) and started displaying an exclamation point. I tried all the troubleshooting tricks to no avail. I called the Dyson support line to see if I could get the unit repaired but they kept trying to get me to 'trade up' for a new model because I was out of warranty. I found this frustrating because I spent a lot of money on this unit just over 2 years ago and now the only option I was given was to spend hundreds of dollars to ...

For the price (and environment), these units should last for more than 2 years and if they don't there should be a way to fix it and not need to buy a whole new unit. I don't know about other people buying these units but I expected Dyson to have better quality machines. So, I guess if you are happy to buy a new unit every two years, this could be the machine for you.I definitely would not recommend this machine to anyone, and I won't be buying any other Dyson products due to the poor quality and unhelpful customer service.

15 February 2023
I bought this machine approximately 1 month ago. I was very happy with the heating function. It literally warmed my entire living room and we were using the home heating less. About 3 weeks into owning this unit I noticed it was stating to get a little noisy. We cleaned it and it seemed fine. Now, today 2/15/2023, the unit started to get a little more noisy while oscillating. We turned it off as recommended. Now, it will not oscillate at all and fan speeds are not functioning either. Again, I was very happy with this unit for the first 3 weeks. I’m hoping it will cool off enough and work again but I’m not overly confident that it will. I would think for the money this unit cost, it should work without so many issues and such a short period of time.
