I bought this big and quiet purifier a month ago and I absolutely love what it’s doing, I procrastinated buying it and wow I’m glad I did. I have 22 foot cathedral ceilings and this taking care of the whole place. Great investment. don't even know it’s running!

Excellent Air Purifier and fan
I bought this two months ago because I needed an air filter and a fan. It does both jobs exceedingly well. The ability to change the fan output angle is fabulous so it’s not too strong. Glad I invested as it’s a big improvement in design from prior models.

Very sophisticated looking and great app
I bought this after the LA fires and I’m so glad that I did. I have this one and the slightly less expensive one which doesn’t have the app. I have to say the app makes a big difference and I love being able to see that the air is clean for my family. It’s quiet and chic and I highly recommend it.

This is an excellent product . I have really bad allergies as I live in Las Vegas . There is much wind and construction and lots of stuff in the air. I am constantly sniffling. This unit has helped a lot .

Robot Looking Upward
I bought for myself for Christmas because I have asthma and I’m highly sensitive to some candles emitting toxins as well as other indoor air pollutants. The product is so quiet and really freshens the indoor air. When the outside temperatures are too cold to open windows to let the fresh air in and bad air out, the Dyson Purifier Big+ Quiet Formaldehyde will make the indoor air just as fresh. I have it in my great room with the living/dining/kitchen where I spend most of my time and it is completely undetectable while running on the auto setting except for the appearance of a robot looking upward. 😁

Purifies beautifully
Works great. I had a lot of allergies while at home until I turned this on. Same day results. Wish it was maybe 2/3rds or 1/2 the size for my 700 sqft living room. Chose this model because of the upward angled circulation.

Saved my life
My building replaced the hallway carpet and the VOCs were so bad, it triggered my asthma. It’s been weeks and the Dyson keeps my unit habitable, and quickly removed spikes when I open the front door.Expensive but cheaper than the ER. I also like the monitoring app and super quiet hence its name.

Fantastic, powerful and quiet
Was skeptical at first if this would have enough strength and be quiet enough, but it far surpassed my expectations. This thing freshens a room like nothing I’ve ever seen. Vertical angle is a very cool feature as well.

Excellent and feature packed air purifier
[This review was collected as part of a promotion.] The packaging is excellent, and it is easy to set up. Pairing the app and adding WiFi was a simple and quick process. Within the first 5 minutes, it automatically updated the software.
It is large and sort of looks like a satellite, but after living with it for a week, it started to blend in well. The bright nickel and Prussian blue color scheme would not fit it, but it looks nice and modern. The wheels on the bottom are a nice feature to reposition the machine when needed easily. You have to be very deliberate when placing the remote on the front, or it will fall to the ground, but if you take your time, it will click onto the magnets and hold it in place.
The app shows a lot of data! So if you enjoy seeing the different parameters, you will love this air purifier. It shows Indoor air quality index (AQI), Particulate Matter (PM) smaller than 2.5 microns and 10 microns, Formaldehyde (HCHO), Volatile Organic Compounds (VOCs), and Nitrogen Dioxide and Oxidizing Gases (NO2). I was surprised to find out this level of data.
We have another popular air purifier that has been running continuously nearby. The Big+Quiet Formaldehyde immediately showed poor air quality when first turning it on. PM2.5 and PM10 of 55. Within a few minutes, the air quality showed "fair" and then "good," which was impressive.
I find it interesting that the most pollution "air pollution" within my house seems to come from cooking. My kitchen doesn't have a vent that vents outside. The AQI quickly jumps to severe, and in auto, the purifier goes to its highest setting and quickly reduces the air quality to "good" fairly quickly. It is quiet on high 52 db per my Apple Watch.
The air temperature that the purifier is reading is about 4 degrees Fahrenheit higher than my home's HVAC thermostat, which is about 6 feet from where the air purifier is sitting. This, I would assume, could be corrected with a software update.
Overall, I am impressed with this air purifier; it helps keep the air in my house fresh.

It truly is big, quiet & very effective!
[This review was collected as part of a promotion.] This machine has many great features including pollen & humidity levels. These are both especially important to our household since we have family members with allergies & asthma. The unit has great output & power but is still very quiet. We often find ourselves checking to see if it is still running. The only negative we have is the size. It is much bigger than the anticipated, is hard to “disguise” in a room, and is not terribly attractive (somewhat resembles a trash can). Because it is so effective & quiet, we are able to overlook the size & appearance of the machine and will continue to move it around the house until we find the best place for it to land. Once again, Dyson has our done themselves!!
NOTE: Curious to see how easy it is to change filters & cost of filters for this unit.

Lives up to its name.
[This review was collected as part of a promotion.] I was thrilled to get this unit 10 days ago, as I had a few issues in our home. One room had a worse than musty odor I had tried to get rid of in many different ways without success. Sneezing, stepping out to the main area where our dog spent most of her time, and recent health issues which made me very curious of the airborne chemicals in the house. I moved the unit around to different spaces every couple days to test what it could do. The bad smell from the smelly room all but disappeared. Our allergies diminished, and I was delighted to see that of all the chemicals tested, only trace amounts of formaldehyde was present, only in the main room and you can see the unit working to reduce this on the app. I am so happy with this product.

Amazing piece of mind
[This review was collected as part of a promotion.] This purifier is substantial and there's no doubt the air in your home is clean. It's extremely quiet. I keep it on auto and have to get right next to it to hear. I really appreciate that everything pulled from the air is trapped in the filter. A nice design feature keeps the remote secure on the machine. And it's great to pull up the app to understand what's being cleaned from the air.

A Must Have!
[This review was collected as part of a promotion.] I've received this Big+Quiet BP03 last week, and I'm impressed.
I am a fan of Dyson design and technology. I’ve been using a TP09 cool formaldehyde purifier, three vacuums and a hair dryer.
My husband and I have allergies, using a purifier fully sealed with HEPA filter, really makes us feel better. We love that it creates more indoor air circulation. Living in the west coast where some years affected by wildfire smoke, having a good purifier added a second layer of filtration aside from the house HVAC system.
This new BP03 is surely a step up in quietness. It shows the actual number of HCHO in mg/m^3 that goes up or down in real time.
I also like the design, it reminds me of r2d2 robot with its can-like body. It is bigger and heavier than TP09, but I can easily move it across the floor - it has wheels underneath.

Greatly improved air quality
[This review was collected as part of a promotion.] The Big+Quiet formaldehyde purifier is perfect for my home with larger sized rooms. It is situated in the living room during the daytime. At full power, it does not interfere with the tv; it's truly that quiet. At night, I roll it on its smooth casters into our bedroom. It has vastly improved the air quality capturing pollutants, gases, and especially important to me, capturing allergens. Having purified air has significantly reduced my allergy symptoms. Makes me feel comfortable throughout the day and helps me get the all-important good night's rest!
When I first received it, I experimented and ran it in a smaller room that smelled musty and it cleared it right up in about an hour or two. I was astounded! It cleared out cooking odors in the kitchen, also.
Not only does it operate so well, it's good looking too. I love the modern design of the unit and the mini remote that magnetically attaches to the front. It's a conversation piece for sure!
Set up was super easy, linking to wifi with the app, and simple to operate. It's a GAME CHANGER for my quality of life, something I never knew I needed. Highly recommended.

Great unit
Excellent unit as you would expect from Dyson. All the right feature features, performs exactly as described. The replacement filters don’t appear to be cost prohibitive. Could always do with a slightly lesser price point, however

Not sure
I’m happy with it except it’s making a clicking noise that is sort of irritating. So guess I’m that way it’s not too quiet.

Wanted to love - didn’t work
I bought this to keep in our daughter’s nursery. It was great at first with cleaning the air, but we noticed that overnight, the quality would get to extremely poor levels, and it would stay that way until morning when we opened the door. Very disappointed and ended up returning as our hope was this would clean the air consistently. Wanted to love it but didn’t work for us.

Take forever to clean the air...
It takes forever for their air to return to green level after any type of cooking. I am talking 4-6 hours of having the machine running and still not getting to green level. Is quiet but not sure if it is efficient or my unit is broken.

The Machine is so large
[This review was collected as part of a promotion.] I was expecting a small appliance and recieved this large purifier. It is stylish but does not have the traditional Dyson look. I ended up putting this in my basement as it is so large and stuck out wth my decor. The product works as promised.
