Customer Ratings & Reviews

The Dyson - Purifier Hot+Cool HP2 De-NOx​ is quite an impressive machine. It is very quiet and delivers heat that is very clean. The app that comes with the product is very easy to use and lets you know how clean the air is inside your home. Plus, it has the ability to set a program schedule although that is only for the air purification and fan only. Since the device complies with UL regulations the heat settings are not able to be controlled via the app and can only be set with the included remote control. The heat can be turned off with the app but only the remote control can be used to turn it on and adjust the heat. I like that the top of the unit is magnetic and the remote sticks to it for easy access and storage. The oscillation of the fan is another very useful feature as I can heat up a fairly large room in a short time by putting this in the center of the room and setting the oscillation to 350 degrees. I got this item mainly for the clean heat and fan capability as I rely on an IQAir machine for doing the heavy lifting of purifying the air in my home. The device does a great job of keeping the air clean while heating up the room. One of the big cons for this device is the amount of power that is drawn when the heat is on. I have seen it as high as 1640 watts when the heat first turns and it typically is around 1300 when the heat is in a steady state. In the auto mode with the heat off it is only about 3W and with the fan on only at max speed it is about 25W. I tripped a circuit breaker one of the first times I was using this device in heat mode. Something to be aware of as it can start to rack up KWHs on the electric bill. Overall, I am very happy with this machine and really glad I got it.

Love that you can't use it to cool areas down or heat the area up, love that it filters out the air to house doesn't smell cigarettes or animals, gets moved around house where needed most, easy to setup

The changed of clean air, I breathe better and sleep better , wake up in the morning no scratchy dry throat, I set to auto for all night monitoring while I’m asleep, quiet, you can access remote the fan and monitor the air quality and temperature on your home thru the Dyson App, wifi or when you’re away, the sensors on both side are very sensitive, it quickly sense the Axe Sprays, Cologne and your cookings once it detects the odors, the air will automatically crank up purified the air.

It really moves air, the heater works great, the air purifier plus digit screen reading of air quality is all super useful! My dog loves to sit in front of it whwn the heater is on. I definitely recommend this to anyone who wants to add a touch of convenient class to their atomosphere.

Works great good little heater and fan takes the coolness off the room

Quiet and efficient. I also like the app where you can turn the fan off and on when you are away.

The Dyson Hot+Cool is exactly what you would expect from a Dyson air purifier. It has a unique bladeless design that means it is very silent at low speeds, and even at high fan speeds, while audible, moves a lot more air than you would expect for the noise. It has this white, bronze/gold, and silver aesthetic which looks classy. The included remote, which has all of the core functions on it, likewise comes with a bronze/gold aesthetic that won’t look out of place on the coffee table. The air purifier itself is pretty compact, sitting ~2.5 feet tall with an ~8 inch diameter. There is also a little screen on the front which displays various air quality metrics, one at a time, which you can cycle through using the remote. Functionality wise as an air purifier, the Dyson doesn’t shake-up the game too much. It is quoted to capture up to 99.97% of particles up to 0.3 micros, and while I can’t test this directly, the HEPA H13 Grade filter gives me no reason to doubt the performance. Speaking of the filter, it should last around a year as quoted on the device, but the app gives you a nice filter health measure. From a measurement standpoint, the filter measures Relative Humidity, Indoor Temperature, PM2.5 & PM10 particulate matter, Formaldehyde, Volatile Organic Compounds, Nitrogen Dioxide and Oxidizing Gases, and an overall Air Quality Index. You can view all of these in the app in real-time, as well as on the information display. You can set the fan speed on a scale of 1-10, or “auto” if you want the fan speed to adjust based on the air quality level (which is how I tended to leave it). The nice thing about the fanless design of the purifier is that the air is reversible, so you can push air either forward or backward from the purifier. Additionally, it can rotate on an ~180 degree axis if you want it to oscillate. All nice to have features for sure, but where the air purifier is most unique is in its ability to blow both cool and warm air from the purifier, making it a bit of a small A/C & space heater in one package. Surprisingly these both work well, and while they won’t keep a large space particularly cool or hot, they can help in smaller spaces or as HVAC augmentation for a larger room. The heater in particular worked pretty well, which while I didn’t test too heavily in the middle of summer, very quickly heated-up and blew a good amount of warm air. This thing would be great for a bedroom or small apartment. To be honest, that is it in a nutshell. The Dyson is a good air purifier, a nice little cooling unit, and an efficient space heater all in one stylish package. In terms of improvements that I think Dyson could make, there aren’t too many. The first would be that I would like to see a more useful display on the front, maybe a bit larger or wider, so you can see multiple air quality metrics at once, not just one at a time. A touchscreen would also be nice to quickly view things without using the remote, but there is always the app itself as well. The build quality is also very plastic heavy for the cost of the machine, which keeps it lightweight, but does result in some creaking if moved or even when rotating at times. Finally, the auto air speed mode is most effective, but at times could ramp-up a bit quickly despite not having the air quality metrics being too bad. Again, all of these are fairly small complaints for an overall successful package. Dyson does it again.

Well I think at this point Dyson does not need any introduction at all, the company at this point is very well known, specially when it comes to fans, vacuum and even hair dryers. but this is my first time owning Dysons Purifier Hot+ Cool, ive been using this at a small office space and so far its been performing perfectly, its a beautiful device and I just want to share my few cents. DEVICE unboxing the device it does not require any sections to be installed you just need to plug it on the wall and youre ready to go. what I have is the golden brown color, I guess its almosy like golden brass I think thats what i’ll call it. this Dyson Hot+Cool offer advanced air purification with 3 stage HEPA H13 grade filtration, so it’s always great to know if your fan support that to make sure the air your breathing atleast helps to be cleaned. they claim it continuously destroy formaldehyde so ill ok Dyson ill take your word for it. FEATURE: Dyson Hot+Cool offers smooth Oscillation up to 350 degree. the remote is also colored that golden brass I was mentioning with minimalistic control that offers fan speed, on/off, night mode, timer and the ability to go from Hot or Cool to name a few. the device supports Bluetooth 4.0 connecting to the app was a breezy it detected the new device instantly. you can also control your Dyson from the app without grabbing the controller or if you’re using this while in bed all you need is the phone to make adjustments with ease. Diffuse mode on the fan is mainly for purification so this fan has 3 features it can do that includes Hot and Cool. EXPERIENCE: I Love Dyson this is not my first rodeo with the brand but having this Hot+Cool is the first time. switching the Fan for Hot it takes couple second but it warms up in no time! having equip with the latest De-Nox that can capture 50% more NO2, it just makes it feel right knowing that this device is protecting my indorr air to make sure im having a great purified air. I havent experience any issue with the fan, the noise level is the same as my other dyson fan and works well during the night. but is this a right fan for you? Dyson is not cheap thats the first thing to keep in mind, Hot+Cool cost $850 so its a hefty price for a fan, but knowing that is Dyson I feel like what youre paying for is definitely worth it from all the studies theyve done to create something safe for your house.

I’ve been using the Dyson Hot + Cool for a while now, and it’s honestly one of the best appliances I’ve owned. The heating works fast and evenly, and the fan mode is great for year-round use. It’s quiet, looks premium, and doesn’t take up much space. I really like the air purification and smooth airflow—no harsh blasts of air. The remote control and temperature control are super convenient, and the safety features (no exposed blades) are perfect for homes with kids. Yes, it’s on the expensive side, but the quality, performance, and design fully justify the price. Highly recommend if you want comfort, safety, and style in one device.

As someone who’s owned several air purifiers over the years, I always end up forgetting to change the filter, and eventually putting the whole thing away because of how much space it takes up. This device solves all of that, as it’s not just an air purifier, but also a space heater and fan, all in one compact design. Since I’ll actually be using it regularly, I imagine I’ll be able to stay on top of filter changes too. Aesthetically, it’s quite beautiful, and instantly recognizable. The clean white against the rose gold base really stands out, and the LED display on the front is bright and easy to read. The airflow settings on this device are amazing. You can choose direct airflow like a normal fan, or a more “radiating” style that sends air out through the top. I’ve never seen anything quite like that before, and I imagine it’ll be especially useful in heating mode so it doesn’t blow hot air straight onto your skin. I’m really looking forward to using that feature this winter. The oscillation is 350 degrees. so no matter where you place it, it covers the room. It also has 10 fan speeds, plus voice control with Siri, Alexa, and Google. The app is very easy to use, and loaded with info: real-time feedback on air quality, pollutants, pollen levels, temperature, humidity, and several other metrics that I’m unfamiliar with. However, with all this said, there is one major flaw with this device. U.S. safety regulations prohibit app control for the heating element on space heaters. The only way to turn on the heat is with the remote. I thought for sure that you would be able to turn heat on from the actual device, but you can’t! I read the manual front to back, but nope, if you lose the remote, you’re out of luck. What’s worse is that I discovered older Dyson models did let you turn the heater on directly from the device, so this feels like a step backward. Another issue Is the “Continuous Monitoring” report. I’ve had this running for almost two weeks and still haven’t been able to get the app to generator a report. The app keeps telling me I need to enable “Continuous Monitoring” to generate a report, while on the same screen showing it’s already enabled. Again, I’ve been through the manual and troubleshooting guide and still can’t get it to work. Overall, It’s a beautiful device, and something I’ll absolutely treasure in my house. I love all the data it provides, and the wide range of functionality. However, as the dad of a 10 year old boy, I know that my remote will definitely go missing at some point, likely on the coldest day of the year, and I’ll be scratching wondering why I can’t turn the heat on from the actual device.

The Dyson Purifier Hot+Cool may be one of the coolest technologies I own. As someone big on using air purifiers around my home, and particularly my home office, I was very excited to not just get an air purifier, but also a fan and heating system as my room consistently is a wildly different temperature from the rest of the house. Right off the bat, it’s worth noting that this is a large box. Luckily everything comes fully assembled. However, my first and largely biggest criticism of the Dyson Purifier is the lack of out-of-the-box instructions. There are a few warning/attention documents and two reminders to use the app, but literally nothing else. I was initially confused and wary about unwrapping the purifier and removing the various tape holding parts together for shipment. There is no instruction on unboxing nor initial setup. Typically, one would expect to see at least an initial startup pamphlet. Even downloading the app does not clear up confusion on initial set up. It’s worth noting that I could not get the QR code on the documentation provided to work correctly on my Pixel 9 Pro phone. Once I downloaded the app, which wasn’t hard to find, I set up my Dyson account and then it went about looking for my purifier via Bluetooth. I had yet to plug in the purifier to power, waiting for something in the app to guide me to do so. Yes, it’s a bit of a “no-brainer” but I’ve set up a lot of WiFi connected technology, and this is the first one that hasn’t provided more guidance through these initial steps on your new product. The rest of the setup was standard – connect to the purifier from your phone, set up WiFi and you’re good to go. I did have issues with it connecting to my standard WiFi 7 (and legacy) network, but when it had no problem connecting to my 2.4Ghz only smarthome device network. While troubleshooting WiFi can come with a myriad of problems, for such an expensive device – and considering none of my Blueair devices have this problem – it’s a bit disappointing. After this was done, however, I’ve had no problems since with WiFI or using the app. Only once you have the Dyson Purifier fully set up can you use the app to find the instructions for how to use it. It’s straightforward: the app can show you both the outdoor air quality for your location and for the room your purifier is set up in. Among the data points you get currently and historically from all the time the unit is on is Air Quality Index, which is the overall air quality parameter, temperature, relative humidity, PM2.5 or particulate matter smaller than 2.5 microns, PM10 or particulate matter smaller than 10 microns, HCHO or formaldehyde, volatile organic compounds, and nitrogen dioxide. Comparatively, my Blueair purifiers only display PM2.5, so the Dyson is cleaning quite a bit more. The app covers almost the same ground as the remote control with one big exception: heating. To meet US safety standards, you cannot turn on heating remotely via the app and this must be done with the remote control. As it’s currently summer, I can’t tell you how inconvenient or not this will be, but not being able to “preheat” my office in the name of safety standards is something I’m comfortable with, although I wish that was advertised elsewhere. Other than this both the app and remote work well. You can turn it on/off, switch to auto mode, adjust fan levels, and oscillation. Regarding oscillation, you have a few degrees of option, including nearly 360 degrees, but where the app shines over the remote is you can adjust where the oscillation originates. For example, you can set a 45-degree oscillation, but with the app you can determine where that is from. From the remote, it’s just where it’s currently pointed. You can not adjust the angle up/downward from the app or remote but can do so physically at the purifier. The unit itself stands about 2.5 feet high, about the same height and footprint as any other tower fan. The white and gold color scheme is aesthetically pleasing and neither of the colors are bright enough to stand out in a way that may look garish or out of place. The front of the unit below the “fan” and above the filters has a small circular screen for displaying information. Using a button on the remote, you can cycle through all the various types of information I listed above. The screen isn’t too bright and is very unobtrusive. The remote conveniently attaches to the top of the unit via magnets. Some of the various functions available include a night mode, where the LCD on the unit is dimmed and it stays at a quieter setting. Auto mode automatically adjusts the air speed based on the air quality in the room. Cooling mode I find to be a bit of a misnomer. There is no actual cooling or air conditioning – it’s just a fan and NOT heating. Heating, again done only via the remote and not the app, allows you to adjust the temperature target. A timer allows you to adjust how long the unit is on. Auto seems to be the default setting. The app allows you to set up scheduling for the device and is super helpful to automatically set up night mode and, apart from heat, can adjust all the other settings such as oscillation. Coming from Blueair purifiers I found this sightly confusing as I had set up an automated night mode, but in the morning when it hit the end of the schedule, the machine just turned off instead of returning to its previous settings. This was remedied by just setting a second schedule for my daytime use. It’s not stated anywhere, but I do believe you’d want to always keep the purifier on, so your room stays with purified air when you enter it. Overall, I’m very happy with the Dyson Purifier. Why choose this machine? I see two reasons: you want both very advanced filtration, and you would like that built into a tower fan that can also heat. If you don’t need either of those things, you may want to look at other models or even other products on the market. While I did find product unboxing and initialization a bit confusing and not clearly explained this is a product that once is up and running is very hands off, so in the long run I cannot count it as too much of a negative. For me, in my home office, that is never the right temperature and frequented by a dog that brings with it various smells, the Dyson Purifier is the perfect choice. I’m in this room for over 40 hours a week and it’s a smaller space, so I want it to be as comfortable and with an air quality that I can feel better knowing is fully filtered and safe for me.

I got my first Dyson air purifying fan back in 2018 and It’s been a great air purifying fan for the most part. The only issue is it has a high pitched buzz from time to time that’s really only noticeable mostly on the lowest settings. With this new model unfortunately it also has the slightest buzz at the lowest settings also. It is nowhere near as bad as my original but it’s still noticeable. Some people may not notice it, for me personally it only bothered me when I tried using it while I was sleeping as I’m a light sleeper. In terms of performance I have always been happy with the amount of air flow these models put out when using it as a fan. The blade less design is also a big plus with having animals and children. We have two mischievous cats so having no blades is one less thing for them to get in trouble with. I have multiple air purifiers but this is the only model I have that detects formaldehyde and I can’t say how effective it is but it gives me a little more piece of mind. When operating the device the app allows you to control all the features, except the heating feature. From my understanding this is a government regulation that you must use the actual remote to operate the heating function. The Dyson app is good and along with allowing you to control the device, it shows you the quality of the air in your home. In terms of the heater, the highest temperature it goes to is 99 degrees, I don’t know how this compares to other heaters as all the ones I’ve used just simply have low, medium and high settings. I’ve always been a fan of the Dyson blade less design and the benefits they give you. My only issue with the Dyson is the occasional high pitched buzz they can make on low speed settings and for the price it’s kinda inexcusable. If you’re not planning to use these while sleeping, I can recommend it, if you are it’s something you want to take into consideration.

I’ve had the Dyson Dyson Purifier Hot+Cool Air Purifier for a while now and honestly it’s one of the best home purchases I’ve made. The airflow is powerful without being obnoxiously loud, and I love that it heats and cools depending on the season so I don’t need multiple devices taking up space.

Super quit purification. Heat is also great, and looks awesome too.

I have a Dyson hot and cold from a few years ago. This is such an improvement from even just a few years ago. The previous generation had a standard HEPA filter, this new generation filter. This new filter Dyson day is a HEPA filter with charcoal and potassium. This is to help absorb the NO2 that can be in your house. There is an auto setting, it runs in the background. When the Dyson detects contamination it kicks on high. I had was putting down some carpet fresh, they Dyson cleared a 12x12 room in about 15 minutes. So if you want the fresh scent from a carpet deodorizer you might want to turn the Dyson off. It’s been super hot so I have not used the Heater. With previous units you can’t turn the heater on with the app, you have to use the very tiny ( and expensive remote). So don’t lose it. This does use the same Dyson app as my precious fan so that is great. When I first plugged the fan in the app said my air was very dirty. It did do its initial cleaning which was about 15-20 minutes. I didn’t even know my air was that dirty. I have 0 complaints (except the heater and the remote). I have always loved Dyson fans and this just continues that. I am not sure if its temperature sensor is totally Accurate. My house AC says 77 and the Dyson says 80. So one of the 2 are wrong.

Fantastic fan and heater. Only issue I have is I can't set the fan to stay on after the heater shuts off.. seems to me that would be a no-brainer function but for the life of me, I can't seem to do it. Otherwise, it is great... great airflow, great air filtration, and heating capability for a small bedroom.

I got word for my mother for mother's day because she suffered from allergies really bad and she told me that the air in her place is completely clear. Now it better and you can tell the quality of air

Needed to get a space heater and decided to splurge on this item. Provides good heat and air and monitors all the particles in the air, letting me know when levels are good or unhealthy

I have had this about two months now. I love the heater fan combo filter it pushes a good amount of air. The only thing I do not like is that it shuts off after eight hours of use.

I feel great knowmy baby is safd with clean air, and acwarm room all winter.
