I use this fan in my sewing room. What can I say? My room is an add on and the AC unit needs upgrading to a bigger size but in the meantime I have this machine to keep me cool on warm days. I can tell the difference in the air quality. Going to get myself another for my bedroom soon. I can control it by phone through the app and my echo.

Home cooks rejoice! Bye bye bacon smells.
If your home cooking includes any kind of searing, this air purifier is for you! During the cold winter months when opening a window is not an option, having this Dyson air purifier is the next best thing in ensuring your air quality and food smells doesn’t linger long after a cook. My smoke detector now rarely gets tripped when I’m searing my steaks after having this Dyson air purifier. That’s quite an accomplishment.
• Auto mode allows to set it and forget it
• Feature heavy and data for analytics rejoice
• Easy phone app integration
• Can flip between front blowing to top blowing
• Alexa compatible…but why?
• Too short and needs to be placed on a counter or table top
• A bit noisy at fastest fan setting
• Bit more money compared to competition
• A bit of an eye sore. My house is not as contemporary as Mr Dyson designed it for.
I do a lot of cooking that includes frying bacon and searing steaks on a hot cast iron skillet. All things that would have smells that lingers for days. The Dyson air purifier exceeded all my expectations and never knew an air purifier can measure air quality with such granularity. My other purifier only shows one number for air quality at 2.5 microns. Dyson has air quality numbers for 2.5 microns and 10 microns. And also show ranges for VOC and Nitrogen dioxide.
Initial setup was super easy. The Dyson requires wifi for your phone app to work. The app is very robust and does 90% of what the physical remote can do. (Apparently it’s against regulations to be able to adjust heating temps via the app.) The filters are $79 for both the HEPA and carbon filter and im not 100% sure what the average lifespan is. Most other purifiers recommend replacing twice a year so this Dyson will be about $160 a year if that holds true. The purifier does have a graph that shows the “life left” of the filter and I’m sure it’s based on the amount of hours used and fan speed. YMMV
Numbers nerd section:
I do recommend this air purifier for folks who love data rich analytics. The app will show you a graph over time with total amounts of “purifying time”. I averaged 3.8 hours a day with 6 out of 7 days of cooking dinner at home. If I continued to use 3.8 hours of level 10 fan speed a day and the rest at normal fan speed, energy cost for me at .12cents a kwh would be would be $5.51 a year. Not too shabby for purified air! These numbers will drastically change if you use the heat feature. With the heat on at fan level 10 and oscillation uses 1434 watts. The heat feature is a nice added bonus but its first an air purifier, then a heater.
I’m glad I got this unit as its by far the most advanced air purifier in the market. Set it and forget it with the auto modes. While it’s a bit pricey, what’s the price of knowing your family will breath in unpolluted air? Priceless.
This is a nice machine. I've been wanting one for a while. I love having a space heater available to me in the winter, my husband likes a breeze in the summer, and we both want to be sure our indoor air is good.
Good for households with kids or klutzes: no moving fan blade and no heating element accessible. To burn a hand, you'd have to hold your hand on to where the hot air comes out for a bit, and most kids would notice the heat and probably not get to the point of burns.
Heat: I keep it around 88-90 degrees to keep it sending out heat in our high ceilinged open level. You can set the temp from the remote, can have it oscillate with heat, and the fan noise doesn't get noticeably loud until you pass level 5 fan speed. Even at that, it's not super loud until about 8, 9, and 10 levels.
Fan: can have air come from front or back of machine. Again fan isn't too loud until you go over level 5, then you notice it more. All the way up on fan speed makes me think of box fan noise level, but a smoother noise. 10 fan speeds.
Oscillation: 5 settings - no oscillation, 45 degrees, 90 degrees, 180 degrees, or 350 degrees.
Air purifier: I don't have anything to measure it outside of the unit itself, so I assume that the filters are doing their job. The display says they are.
Tilt: can tilt the direction up or down and it will still oscillate even tilted. (Nice feature when you want to keep several feet under the table warm!)
Remote: easy to use, magnets to the top of the unit.
Cord: not super long, so a pro if you don't like long plug-in cords, a con if you like lengthy plug-in cords.
App: cannot control the heat from the phone app. :( I was disappointed in this. However, once you have the heat on using the remote, you can then control the fan speed and oscillation without those actions cancelling the heat. Can control air flow, fan speed, oscillation, night mode, and timer in the app. Knocked off a star for the connectivity -- cannot turn on the heat, nor control the temperature through the app or Alexa, and using Alexa to power on and off has been hit or miss. Easy to setup in the Alexa app, though.
Remembers what it was set on when you unplug it and replug it in to use it in another location. The machine returns to the center spot when you turn it off. It has a Dyson logo on the front and center to easily help you place the unit centered. Easy to pick up from the back/top to move it around (even when using as a heater, you can pick it up and move it just fine).
It's a chunk of money to spend, even on a three-combo machine, but Dyson makes a good product. Consider the non-link to save some money, but if you want most of the features in a handy app, you'd need to buy the link version.
Nice smooth air output whether using the cooling fan air or the toasty warm air of the heater.
I imagine this will be much easier to keep clean than either a traditional fan or heater! No grills or blades to get to and clean.
We've had good luck with other Dyson products (vacuums, desk fan, hair dryer) and hope to with this one as well. All said, I think we're going to really like having this Dyson product!
I really needed this for my master bedroom, because it gets really cool at night. There heating is perfect, and in the summer this will save on air as well.
My home is connected, so this works nicely with my home security which is Alexa enabled too. Voice commands are simple, and controlling it is too. The included remote is easy to understand.
It's nice and quiet compared to the other fan I was using, amazing product.
But like most things, there had to be at least one con. For this one, it's the price. Dyson is a big brand, and do offer 2 year warranty. But I think some might not be too quick to kick out the cash. But, it's so nice, you might want to give it a shot. Once you get it, you'll be happy.
I bought this to help with the summer months, and to help with the air quality in my bedroom. I also bought the taller version (TP04) for the living room which I will also review.
The fan itself is great! It can move some serious air if need be. The tilt function is nice as well. Makes it easy to point it at the bed at night to help move the cool air around from the AC. The filtration system is great. I have noticed its easier to sleep at night (grew up with Asthma and some allergies, i also own a dog). I haven't been nearly as weezy this summer like last summers. Honestly I just set it on Auto and let it do its thing. I will say the sensor for detecting pollutants is pretty sensitive. If when cooking and some smoke from cooking gets in the air, both fans will kick into high gear until its all cleared out. Same goes for when its cleaning time and the dust starts to fly. I havent got a chance to use the heater function yet, but I'm sure it will work well.
The app is also amazing! Super easy to use and makes it nice to be able to adjust both fans without looking for the remote. I can also change the fans on the app if im not at home (in case you want to turn it off or turn up the fan speed). It really is an easy app to use. Its nice it tells you the filter life as well.
I know these Dyson fans are a little pricey, but i have owned many cheaper fans and have not been this happy with them.
I have been looking for a decent room purifier for quite some time. I suffer from allergies and asthma, so come winter time with the dry heat, needless to say I become a mess at night trying to sleep and breathe. I have always liked the look of these Dyson air towers, and when an opportunity arouse to sample this product for free in exchange for an honest review, I figured why not.
Fresh out the box it was an easy setup. You only need to open up the filter chamber and install 2 filters and close it back up. Plug it in and your good to go. It is recommended to download the dyson link app in order to properly setup and maintain the tower. Apparently there were many complaints on the app page that the app was compatible with only either 2G, or 5G wireless routers ( can't remember which!), BUT the issue was fixed with newer towers (including this room) where it is compatible with BOTH, so you will not have any problems. I did not have any and connected instantly after entering my wifi password.
The tower itself is a good "smart" tower. You can use the app so set timers or set on/off schedules during the week and which days specifically. You can also get weekly/monthly reports on the air quality in the room. You can choose the oscillating speed from 90,180, to a full 360.
The tower itself has the ability to heat or cool a room. Please note this is NOT an air conditioning unit. The "cooling" feature is simply a decently powered fan. It does not compare to an AC unit. The Heat feature tho is pretty good. i would not say it should replace any space heaters you may have, but if you were sitting next to this it would keep you cozy and warm enough.
The one AWESOME thing about this unit is not the unit itself, but the remote! It is magnetized and latches on to the top of the tower with the slightest of touches. I can't believe ALL appliances and electronics do not have this feature pre-built in. How many times have you misplaced a TV remote or electronic remote. This is great.
As far as the purification ability of this tower, yes it works and yes it does a decent job of keeping the room I sleep in less stuffy from the heat and other materials in the air. But I am sure you could get the same results from something that costs half what this tower costs. I would not recommend this at full price, or even 3/4 the price. It would have to be about $200-$300 cheaper. It's a good unit, but for the price I had to take off 1 star from my review.
I bought this for the master bedroom to help me sleep at night. I have two dogs that sleep in my room and due to allergies I was having trouble with congestion and this helps a ton! I set it to "night mode" and "rotate" and let it run 24/7. It's quiet (almost silent) until it detects something in the air and then it kicks up automatically until the air is clean again.
I clean the filters every few months (a simple process that takes less than 5 minutes).
Although fairly expensive... I am considering buying more of these for the other rooms of the house.
Since my wife and I are expecting a baby we had decided to give this unit a try. However I was very skeptical due to its price and on how this purifier would help in any way. I was shocked. We recently had some brush fires in the area and the whole house was smelling like smoke. However we had the unit on inside the bedroom and you can see on the monitor how bad the quality of air was. After having the unit on for a couple of hours the smell of smoke had dissipated. My wife and I were amazed on how well this unit has worked. The room also seems a bit cooler than having a regular fan. Thumbs up to dyson as this is our second dyson product we own.
A:AnswerHi there, this is Kelly with Dyson. Both the HP02 and HP04 machines feature both heating and cooling, in addition to purification. The HP04 is an updated model. The HP02 has 180 degrees of oscillation, while the HP04 will oscillate 350 degrees. The HP04 also features a backward airflow setting, so in cooler months if you don't want to use heat, but still purify the air in your room, you can have the air flowing out the back of the loop, rather than directly in to the room. The filter life in both machines will also be the same. Hope this information is helpful in making your decision!

A:AnswerHello Carlos, this is Kelly with Dyson. The HP04 is the Dyson Pure Hot + Cool, while the TP04 is the Dyson Pure Cool. Both purifiers are WiFi enabled and can be connected to the Dyson Link App. The HP04 will produce cooling air flow plus heat, whereas the TP04 does not have the ability to provide heat.
Dyson Customer Support
A:AnswerHello Belen, this is Kelly with Dyson. Great question! The Dyson HP04 Pure Hot + Cool's filter will have 4382 hours of life. If you were to use your purifier 24 hours a day, the filter would need to be changed after about 6 months. You can monitor filter life right within the Dyson Link App.
Dyson Customer Support
A:AnswerHi there, this is Kelly with Dyson. I am happy to let you know the differences between the HP01 Hot + Cool, and the HP04 Hot + Cool Link. Both machines are designed to intelligently purify, heat and cool you. The HP04 model is Wi-Fi and Bluetooth enabled, to allow you to connect your purifier to the Dyson Link App on your smart phone device. Within the app you can control the machine, set up a run time schedule, view air quality and also the remaining life on the filter. The HP01 will not be able to connect to the app. The HP04 model also has an LCD display. HP01 will oscillate 180º and the HP04 oscilaltes 350° and also has backward air flow.

A:AnswerHello Lima, this is Kelly with Dyson. The major difference between the Dyson HP04 Pure Hot + Cool and the HP06 Cryptomic, is that the latter will not just capture formaldehyde, like the HP04, but it will also destroy it. The HP04 will capture it, and it will remain in the filter.
Dyson Customer Support
A:AnswerHello Amy, this is Kelly with Dyson. Great question regarding the Dyson HP04 Pure Hot + Cool. The 360° sealed HEPA and activated charcoal filters are designed to remove gases and capture 99.97% of microscopic allergens and pollutants as small as 0.3 microns, including bacteria, mold, odors from cooking, scented candles and car exhausts, which includes VOC's.
