    • Surprisingly Quiet, Exceptionally Efficient: A Year with My Dyson Fan
Style: HP07
First, I've owned this for almost a year. And when I mean almost a year, I mean in three more weeks, it will have been a year. I have to say, in regards to this purchase, this device exceeded my expectations. Not only did it exceed my expectations, but a lot of the complaints I have heard, I don't see here. Or I don't hear, for example, the loud noise. This fan is just wonderful. And keep in mind, I am just getting ready to replace the filter now. It's at 4%. So, this filter claims it should last about a year. And keep in mind, I have been putting this fan through heavy use throughout the year. I have it scheduled throughout the day to go into auto mode or to start blowing during certain times. During the winter, usually any time between 8 to 9, I will have this fan having heat come out until midnight when I have an auto shutoff scheduled. So, yeah, this, believe it or not, has replaced our space heater. It just works so well. And I'm shocked at how well this specific device has worked. In fact, most likely near the end of this year, I'm going to have to buy another Dyson. Not this model, but basically another model that's smaller that could fit somewhere else within my apartment. Again, in terms of the noise level, it's no different from any other fan. I want to say, unless you have something wrong on the inside, this fan is perfectly quiet. This fan does pick up a lot of dust. It's very easy to clean. And again, it just operates wonderfully. Now, I have this fan at the edge of my apartment where my Wi-Fi could reach. And again, it still works wonderfully. If I accidentally leave the heat on and I know I need to turn it off, I could just get on my Dyson app and just completely turn it off. It integrates well with Alexa. Unfortunately, it does not integrate well at all with Siri. And I think it has to do with the United States regulations that you cannot use the smart app to actually schedule heat to turn on. Unfortunately, in the United States, that is now against the law. So if you're not a big fan of that, please call your congressman or your senator's office. Because again, the fact that you could just schedule things is great. Not only that, but it makes it safer. Also, it makes it safe that you could actually turn off your fan at a certain time so you just don't leave it running. Again, this is a wonderful buy. If you're in an apartment, you will appreciate it. Again, it's pricey. Keep that in mind. But it's one of those things everyone in my household just loves. At first, there were complaints because of the price. But again, it's something that has grown on each and every member of my house. So please consider this purchase. It does exactly what you want. And the things it does not do, honestly, you could blame that on your congressman. ... show more

    • Best air filter / fan !!
Style: HP09
Absolutely amazing. These fans are quiet, and have the best air filtrating that we’ve ever had (2 dogs and 3 kids)! We have them in most rooms now because they work so well. My wife and daughters love the heat option in the winter too. The price is certainly limiting, but we wait for them to go on sale. Scheduling on the app is super easy to use too ! ... show more

    • Great Product!
Style: HP07
This has been a lifesaver in our daughters room. Super easy to use, and heats her room nicely on extra cold nights when our HVAC doesn't keep up.

    • Dyson Customer Service is Horrible
Style: HP02
After only a few weeks of having the HP02 it completely died on me. Wouldn't turn on at all. I contact Dyson customer service and they offer to replace it for me - great! But the HP02 was out of stock so they said they would let me know when it was back in stock and would send my replacement. A month goes by with no word so I reach out again. At this point I said I would take one that was cheaper, I just really needed it before my baby was born. Okay sure no problem just send us back the broken purifier and we will send a new one out. The rep I spoke to A MONTH AGO said nothing about sending the old one back. (Looking back I am sure they take them back to refurbish them) but in my mind, the rep never mentioned sending it back so why would I hang onto a dead fan when they told me once it's in stock a replacement would be sent? I threw it in the trash. In this economy I can't afford to just throw away $500 but that's exactly what I had to do. They need to teach their reps to explain the process a bit better to the customer. Most companies do not ask to send back the broken product anymore. Go to their Facebook page and you will see 1,000 reviews just like mine about their customer service and people waiting on replacements for months. I was a die hard Dyson fan with multiple vacuums and purifiers by then but never again. ... show more

    • Mixed Feelings
Style: HP09
I bought this during the summer because it says that it’s supposed to cool. It does not cool. It’s easy to use, but it’s large and noisy. It’s not worth the money I paid for it. I kept it because I had a problem with another brand and had to mitigate some damage done to my home by the other brand. It does get rid of all odors, and I am hoping that it will improve my air quality. I really like that it shows you the amount in your air of several different pollutants that could be in your air. It didn’t say that there was anything wrong with the air for several weeks, but it did detect a tiny bit of CO when it was placed near the gas stove on a day when we were doing a lot of cooking, so I assume that all of the detector functions are working properly. The heater function works nicely for keeping my dog warm. It seems like too much money for what it does. The remote has to be placed face down to stick to the device. It would be more useful if you could use the remote without having to pick it up each time. ... show more

    • Works great
Style: HP09
Works perfectly the only downside might just be wind speed I wish it was stronger you have to almost be in front of it to feel it. Otherwise it does clean the air in my room rather quickly and allows me to monitor contamination in the air.

    • It’s quiet and efficient
Style: HP02
Since it has turned cold the heating element is wonderful, much better than my small room heater. Also very nice in the summer with the oscillating fan blowing cool air around. I keep it on the night selection so it’s soundless during the day and night. A good investment.

    • Cannot turn on heat from another room, even with smart app.
Style: HP09
Beware! Because of regulations (UL 1278), you cannot turn the heat on without using the remote control in the same room. You cannot use the app on your phone to do it. Dyson's web site did not make this limitation clear enough for me to notice it. Hope you are smarter! The regulation is intended to promote fire safety, and I can see the value for cheap, poorly constructed heaters. But this is a well-built, thermostatically-controlled unit, with no exposed heating elements. It deserved better from our government. ... show more
