Dyson Purifier Hot and Cool HP2 De-NOx

Build quality is great, Cooling / Heating Air flow is good, Filtration is awesome. Too loud / noise to operated at fan speed above 5. App wifi connection is too slow, feel it's a costly trade to have wifi connection. Smart Home Matter / HomeKit connectivity could be a better upgrade.

Amazing fan, very nice design and colors. Heats my room very well and I never notice the noise. I love the online functions for being able to check the filtration and control settings on the app. I am addicted to checking the graphs and seeing how my air quality improves.

NO, I am not satisfied as the unit does not sufficiently cool the room.

Using the fan for air filtration. It works amazingly well

[This review was collected as part of a promotion.] This air purifier really has made such a significant difference in my health and quality of life. Because it is constantly filtering the air at the highest left I’ve noticed fewer allergies, better scent in my home, and even deeper sleep. I don’t get sick or congested as I did before. I can’t imagine not having this going forward!

[This review was collected as part of a promotion.] I was give this unit for test but I have found this unit too big and also a bit confusing with the UI.

I purchased this as an alternative to a window unit air conditioner. It’s not an air conditioner but does an incredible job moving air and keeping my spaces cool. The air quality information is helpful and the purifier works well when air quality spikes. I’ve only used the heat function once but know it will work well in the winter months. Overall, I am satisfied with my purchase. It’s a lot of money, but the many functions it covers are worth it.

I already love my Dyson vacuum cleaner, now I can add the Dyson Purifier too. We have used the purifier every night for the last 6 weeks, the air quality has improved in our home and the quiet cool keeps us perfectly comfortable. Thank you Dyson for another great product!

Great air filtration system with silent sound. Can’t wait to see it perform in the winter.

[This review was collected as part of a promotion.] I haven't had this product very long but I can tell a difference in the air quality in my house, especially my pet room! It's a little heavy but with all that it does, it's worth it. Heats and cools fast. Low noise.

The product is really good, but it consumes fair bit of electricity

The Dyson had been planned as a safe heater for a nursery where little hands could not get burnt. We found that the heater was set at 21 degrees but it did not turn off (despite this setting). We woke up to an extremely hot room with the baby rooms thermostats that we also use saying 25.

[This review was collected as part of a promotion.] Got this product 3 days ago and it has helped bring down the temp in the room quickly, the fact that it has many different coverage choices ranging from 45* to 350* helps circulation in the room (no more stuffy air) also tried out the heating feature and it definitely does the job, the room got hot in no time. Only thing that might be a slight issue is the noise, it can be little noisy but the overall efficiency of the purifier makes up for it.

[This review was collected as part of a promotion.] This slick, ultra-quiet purifier arrived just in time for the hottest day in Silicon Valley so far of 2025... it quicky transformed the air around me to be crisp and refreshing, as if I was taking a walk in the morning forest. It's so powerful that I didn't need to turn on the central AC because the bedroom was already cool enough with this running at a level 5 power at night. In fact it's so good, I'm considering of moving this to my elderly father's study room which can often get too hot or too cool... but I'm just afraid he might not be able to intuitively understand the buttons on the remote control, nor where to secure the remote control on the device. Maybe these are areas for future product iteration, along with some kind of smarter cord storage? I also think Dyson can use smarter branding for this device so that folks don't need to guess around on what seems to be molecular acronyms... All in all, the above aspects are not enough to detract from my five-star rating due to its power, projection, and aesthetics - the LCD screen is so clear and high quality, not to mention the coloring and finish - it looks and feels superb...!

I bought over a month ago just as a cold snap hit, I have a large open plan living/dining/kitchen and the heat function is superb, warms the space up very fast and the temperature control is excellent, once warm the areas stay warm with the heat even going into the bathroom and bedroom. It doesnt take up a lot of space so thats another bonus.

[This review was collected as part of a promotion.] Absolutely love the Dyson Purifier Hot+Cool HP2 De-Nox . Solidly built, packed with features, sleek and blends in with any decor. Unit easily covers 25 x 25 open room, providing nice air flow, low noise, and I can tell an immediate improvement in air quality from the filtration. Phone app is wonderful, allowing remote access to features, adjust air flow and direction, graphic views to monitor air quality, even when away from home. Only heat function is not available through the app. Heater worked great and took the chill out of the room. For me, the Purifier Hot+Cool HP2 De-Nox is a must and I am very satisfied with all of its features and performance.

[This review was collected as part of a promotion.] Although I have only had this new Purifier Hot+Cool HP De-Nox for a week, I can already tell a difference in my air quality. The first day I used it in my kitchen, it rapidly removed cooking odors. After that, it has been in my bedroom, making my breathing better while sleeping and reducing my allergies. I also love the app with its multiple features. Although I do not need heat now, the fan function does make the room feel cooler. It has great 360 rotation and also tilts, covering a wide area. All that with minimal sound at even medium settings. To top it off, I think it looks great, too.

I love this item. It is really sensitive to pollutants. I brought the model which was only cold but ended up upgrading as the heating is more beneficial for winter. Gave the other model to my daughter.

[This review was collected as part of a promotion.] I have been using the Dyson Purifier for a few weeks now and love it! It was very easy to make sense of the controls and install the filter, this shouldn’t cause any issues at all. The design and casing feels high quality and sturdy. I personally think this is extremely versatile and I intend to use it continuously throughout the year as it heats up to 99 Fahrenheit so it will be perfect in the winter too, however I am using it as a cooling fan in my bedroom as it is warm now. The 1-10 setting allows me to manually set it to exactly intensity I desire and I like that it can rotate 360 to fully cover a room and I can choose which direction I want to set the air flow. As someone that is health conscious I appreciate the built in screen so that I can monitor air quality, humidity etc. I love being able to see when I will need to clean the filter too, very useful! Overall, I think this is an amazing product I will definitely continue to use the air purifier for the foreseeable future. It’s another product in my Dyson home that reminds me of why I buy Dyson products in the first place!

[This review was collected as part of a promotion.] I received this product a week ago, and I am absolutely loving its function and features. First, I love the auto function. It detects when air quality drops or hits a preset level and turns on. Adjusting the fan speed itself to maximize filtration, and shuts off when quality returns to green levels. Also, the heating and cooling functions work great. Both maintaining quiet functionality when below the level 8 fan speed. Lastly the app itself is great. It provides a detailed breakdown of both inside and outside air quality, humidity, temperature and filter health. It is also very user friendly and is easy to control the unit itself. P.S. the unit itself also looks great with top notch build quality.
