I was skeptical and hesitant to purchase this unit because of the steep price tag. But it turned out to be one of the best online purchases I’ve made. It is powerful yet very quiet. The air quality sensors are quite accurate. It detects changes in the air when my wife cooks and self adjusts the speed accordingly. It works well in a large room (mine is ~1500sqft) and I could feel the breeze 20+ ft away. Setting up was easy and with the MyDyson app you can view different parameters including Air Quality, PM2.5, PM10, VOC, NO2, formaldehyde, Humidity and Temp. Highly recommend it.

I’ve had this for a month running at full power 10 setting and have to say that this is only a decent air purifier. Its CADR is only 313- meaning there are many smaller and much cheaper air purifiers that are much more efficient than this machine and it shows.
I mainly purchased this for dust which this thing doesn’t really excel at. You WILL still need to dust everyday with this machine.
It excels in removing very very fine and “invisible” particles and air- sort of. While it’s great at detecting this stuff it takes a very long time to clean a room. I had it in a smaller closed off 300 square foot room. Smaller than the recommended 1000 square feet.
Spray cologne or open nail polisher and the app shows a chart that it detects it. It will often take a 30 minutes to more than an hour to clear this out.
If someone in the nearby kitchen makes cookies and burns them again the smoke that seeps into the room will be there for a while. You’re better off just opening a window than relying on the machine to clear that out.
For $999 I expected a lot more. I wouldn’t mind the price if it was a power house and was efficient but it’s not unfortunately. I do like the design and how it can work as a light fan but honestly I just need something that works and works well so I will be returning the device. 1 star rating to offset the 5 star kool aid drinkers.

I love this machine. Best purchase ever. My air is clean and clear. It’s quiet and fits perfect as far as luxury decor.

It is exactly as quiet as they say. I love it! I have had other purifiers and this one is definitely at the top. Runs quietly until something is in the air. It’s very sensitive and I think that’s why I love it the most. It picks up on everything. Pricey but worth the money!

I’ve got Coway Airmega AP-1512HH, Mila Air Purifier, BISSELL air320, BLUEAIR Blue Pure 411, and now a Dyson Big+Quiet. — Yes, too many.
BISSELL fan is annoyingly loud with a tiny rattle to it. Dislike it, put it in garage.
BLUAIR is just tiny and when fan spins up is loud… you gotta have a tiny room for it to make sense, I guess.. Coway is just so much better in every way.
Mila is fine, I have it in an office. Filters seem expensive for size, but the auto fan control works well.. 90% of time its totally silent. If someone burns something in kitchen its quick to ramp fan and gets a bit loud, but that’s what you want, to get air clean and ASAP and it then gets silent again. It’d be great if not so pricey.
Coway seems best value for money. Fan moves a lot of air for how quiet it is. Filters are cheap enough. Its very quiet on low speeds, does get loud at max fan but it moves a lot of air. Only has like blue/green/red light doesn’t give exact numbers for particulate.. only downside, but its so cheap can’t complain. Auto fan control works. Its just hard to beat the Coway the value is so high.
But then we’ve moved into a new house with a big open floor plan and 12ft ceilings.. its just a big area. None of others really handle that much space, so got a Big+Quiet. And no regrets.
– It is big, so normal rooms probably silly large. But in big enough room it doesn’t look out-of-place. And IMO it generally looks good.
– With fan at 10/10 its quieter than Coway/Mila at max fan while moving more air. With fan at 5 its quiet, but audible if room is otherwise silent. But if couple people are in room doing anything they’ll be making too much noise to hear it at 5/10. When fan is on auto and drops down to 1-2 its really hard to hear even in a silent room.
– The app works fine. Remote works. I prefer app.
– The wheels are nice. Not that you’ll move it often, but when you do it glides effortlessly. We’ve been testing out how it looks in different places and wife rolls it around and doesn’t ask me to move it for her.
Longterm probably won’t move it often, but still nice feature.
– I like how long the filters claim to work. Don’t mind paying a lot for filter if it’ll last awhile. Mila for example has a $59-99 filter they want you to replace every 6 months, its just crazy expensive. Dyson says up to 5 years for $170 filter.
And I really nothing to complain about. If you have large area this is air purifier to get.

There are always people who hate a product and claim “BuT aCtUaLlY” about one of its features… I run this thing full power every single day and outside of the filter getting used (You know, as its supposed to) there is nothing wrong with this. It is the best air purifier that you can buy for the money, period, anybody claiming that the cheaper ones work just as well can keep on inhaling those fumes that make them so smart in the first place. I love it, it cleans rooms out in a sufficient amount of time, and the app is relatively simple to use. Plus, the filters do not cost that much money to replace at all, which when it comes with a lifespan of 2 years is pretty nice!
All in all, if you have the money and you care about your air quality then this is a no brainer. I read some guy’s review on here where he was trying to push a unit that costs like $200 as being better…. sure my guy, I can also eat a steak from a HungryMan box instead of the Ritz Carlton right?

This is the best Dyson product I’ve owned. I like that it has wheels and that it’s quieter than the cooling/heater fans. It does also cool the room better than I expected. I smoke inside so it really helps clean out the air. I also have the humidifier and two of the cooling/hot fans in other rooms, as well as a vacuum. It is super expensive and wouldn’t recommend people buy this unless you don’t have a budget as it’s only marginally better than other air purifiers I’ve tried which you can find for under $300.
