      An Amazing Device Second to None!

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      It is not comparable to anything ever made. It is worth every penny.I`ll dig into to this more, but overall the Dyson Pure Hot+Cool rocks. We have a house of teens and pets, so lots going on. One daughter in particular suffers from allergies and we`ve had another HEPA filter in her room running at night to help her. After the first night running the Dyson Pure Hot+Cool, she came downstairs and mentioned how that was the first night she was able to sleep through the night. For no other reason than that would I buy a second unit, or recommend buying 1 in the first place. This product is essentially plug and play, the instructions are short and easy to follow. The remote is nifty. I was worried about losing it, as it`s on the small side, but it has an internal magnet and when placed upside down on the top of the fan, it stays solidly in place. Multiple fan speeds are available, including a nice night time option that quiets the fan even more than usual, this is overall a very quiet machine. You can also opt to change the airflow from being focus straight out or in a wider diffused pattern. As is true for most quality fans, the fan can be set to either rotate or remain in place. The heater function is a bonus as the device can be set to warm the area to a set temperature and then maintain that temp. Lastly, and perhaps the absolute best chunk of functionality, is the mobile app. Once downloaded for IOS or Android, you can remotely monitor the device and change any of the above mentioned settings BUT, and this is not mentioned in the guide that came with the device, you can set up a schedule for each day of the week for when the Dyson Pure Hot+Cool will turn on, whether to cool or heat, but also to monitor the level of cleaning the HEPA filter is performing. Graphs of the devices performance are available. In all honesty, other than the price is above what you will find for other fans, the amount of functionality unlocked within the mobile app makes me thrilled that this is now part of our household and I plan on purchasing a second unit for the Family Room.

      Pretty fan but not so sure about purification

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I needed a secondary heating as well as an air purifier for master bed so why not go for dyson purifier which does the two? I had a dyson fan which was quite noisy even at the lowest level, that was a concern. Am I totally satisfied? Probably not and here goes why. * This unit is significantly quieter than the old one that I had (AM05) when it is in the lowest setting. But not necessarily at high level. * The unit does produce hot air and could serve as a fan. When it is running in heater mode, the unit does get hot (the inside of the ellipsis) so requires extra caution with child. * You can schedule heating/cooling schedule via dyson app. I setup 4am to 8am to heat the room and it does go on at the highest level and producing a lot of noise. I tend to keep turning it off when I wake up because of that. * I am not so sure about the air purifier function because we ran it in a room where we could clearly see the dust through the sunlight but it didn't help. Also, even though the unit observed the quality goes above the target in the app, the app didn't show that the unit ran during that period -- in the same graph, you can see whether the unit was active or not. According to that graph, the unit was just sitting there doing nothing. What's the point of having continuous mode? All in all, it is a nice toy and something that pleases your eyes if you have one. If you are a utilitarian, just buy two for each purpose at the same cost but not this one.

      Great product, high price though!


      If these were about $350, I'd buy 10 of them.... but since they're so expensive, I bought one of them. The product works great, the wi-fi feature is actually useful and the graphical information very helpful. Here's my wish for this item: I'd like to remove natural gas from my home as: it pollutes about half as much CO2 as coal; having a natural gas supply to my house increases my homeowners insurance $600/yr more than it would be without it, due to risk of fire/explosions; and having two circulation pumps plus a boiler plus pipes running all over the place already takes a decent amount of electricity as well as causes a lot of places where I could have potential water leaks in my radiator system that's nearly 100 years old. So, for my 3300sqft 6 bedroom home, I'm looking to go all-electric - even with my hot water heater now that electric heat pump water heaters cost 75% less to operate than a natural gas water heater. My only issue with this is that I'd like to be able to constantly monitor this, have it work with a home automation system, and have individual heating/cooling controls for each room, even if I'm half-way across the globe. So, if this could be a more automatic portal, I'd instantly get rid of my boiler, circ pumps, and radiators, and I'd have individual temperature control in each room, and I'd also have air purification in each room - it couldn't get any better than this. I don't need air conditioning, as I'm at over 7000 feet in elevation in the mountains of Arizona where the high rarely gets above 83 degrees, and that's just for a few weeks, and only during the peak of the day. So.... come on Dyson, you're so close to making this perfect, I think it would only take a little effort from your mobile application development team! Love it! Buy it! Wish I could buy a lot, lot more of these!!!

      Good, but .....

      • My Best Buy® Elite MemberElite Member

      I love dyson products. Have 2 of their vacuums and hair dryer. Now I decided to get the fan/purifier. And here are my thoughts. Pros: - good as a purifier coz I don’t have stuffy nose at night anymore now that I’m using it. - it has built in timer for up to 9 hours - it’s bladeless - love the blue color - haven’t use the app but I can see how it can be helpful and control everything from there and see your room air quality - easy to clean Cons: - expensive, both the purifier and filter price - fan is not very strong as compared to a vornado, even at the highest setting. But this could be becoz of the purifier feature? I dunno - can be loud at highest setting - it’s just a fan so don’t expect it will blow you cold air when it’s hot I will probably give it 5 stars if it’s not that expensive. I just feel the price is too much for what it does. But I decided to keep it anyway, mostly for the look, purifier feature. I wish dyson would come up with washable filters. Then maybe the price is more justifiable.

      NICE FAN

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      This fan is really nice. It offers a high quality filtration and a very nice app that will give you all kinds of feed back and information regarding the quality of your air and how much it is filtering. You can also control the fan from the app so you don't always have to find the remote to operate it. It's a little on the small side but puts out pretty decent air flow. You can turn it down to almost no noise or turn up the air flow and make it pretty loud. There is also an "auto" mode where it monitors the air quality and adjusts the air flow accordingly. As for heating / cooling.. The heat is instant and can work as a very nice space heater. I'd say the cool is just okay. It takes room temp air and blows it out slightly lower in temperature. Don't expect it to feel like air conditioning, but its better than nothing and cheaper than A/C. Overall, I like it. But, I returned it for the other Dyson fan that only cools which is much cheaper but still filters the air. No heating or phone app for this cheaper Dyson though.

      Fantastic All-in-One!

      • My Best Buy® Elite Plus MemberElite Plus Member

      I purchased this unit even though I currently own several Dyson fans/heaters but the fact that this unit has the addition of an air purifier changes the game. I suffer from bad allergies and have been looking for a separate air purifier but this unit gives me everything I need for summer, winter and most-of all, spring allergies! It was up and running in minutes and my first night with the unit had me breathing much better when I woke up...not as much coughing and congestion. The app gives me tons of info and I've been controlling the unit from work…pretty slick. The only drawback is that is does not work with Apple HomeKit. Hopefully, Dyson will fix that in a future update.

      This is awesome! Heats & cools as it cleans the air which is super nice for anyone with allergies & asthma. It is loaded with features including oscillating, angle adjustment, sleep mode, temperature settings,2 timers (one for duration & one to automatically turn on on certain days/times) & best of all you can operate it on your phone on their app..Check your humidity reading,air quality rating, indoor & outdoor temp. Etc. on your phone from anywhere. Plus, you can turn it on, off, change settings etc.. No more getting out of my comply chair on a cold winters nite to turn on the heater in my large cold bedroom before bed. It warms the room up fast & I can set it to my desired temperature & it will keep it at this setting for as long as I want. Well worth the money if you can afford it!

      Quieter even on full speed then the 3 other brands

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      I really like how this how it keeps the airflow cool without being a A/C. It is also easy to switch to hear and you can choose the temperature level from lower 60s to 99°f. It also has a night time mode that dims the light and makes it run quieter but I've grown accustom to the purifiers running in my room. I have a rare for of vasculitis so it's important to keep the air around me clean. The only down side that I've found is that the remote control is the only way I've found to change any settings or to make it do what you want. If you can do it on the tower then I haven't found it yet but it's not been here that long where I've had time to check fully. I also like that the fan is covered because we have a pet bird so it's a lot safer for people who own pets and you get children.
