Customer Ratings & Reviews

Fantastic air purifier. We are a family of 5 and someone is always sick, has allergies, or making a meal that stinks up the house. This was definitely an investment but I was willing to pay for a Dyson for Dyson results. The app is flawless and offered all the functionality you could possibly need, the sensors are very good at identifying airborne impurities, and it’s whisper quiet. Even on its highest settings it blends into the background. If you have an open concept home and you need to move a lot of air, don’t look any further. Our air quality is noticeably better and so are the families allergies. I’m looking to pick up another one for our bedroom in the near future. Absolutely love this thing.

Amazing ! You don’t even hear if it’s on or not . It’s notify you if levels are high right thru the app .

With a cat and young children, I’m always looking for ways to keep local odors in check and improve long-term air quality. Diaper genies only contain so much and cat dander can cause or contribute to allergies and respiratory issues. I also do a lot of cooking and BBQ on the back patio and the kids coke and go which means smoke and pollen getting in the house. Dyson products have long been known as redefining the cleaning and cooling space with hi tech ways of moving air so it only seemed natural they would get into the air purifier business. The Big and Quiet apparently started as a commercial air purifier for offices during Covid which is reflected in its high price, large size and industrial looks. They managed to drop the price for the home market and I’m thrilled to have one in my home. Despite the bulk and looks, the Big and Quiet is surprisingly light. The top and cylindrical body is mostly plastic but not cheap feeling, and inside is mostly hollow for the air filters with the rest being the black magic Dyson uses for moving air without moving parts. The unit has some nice casters that allow you to wheel it around easily and the top slots in and can only be mounted one way with molding keys and the chip interconnect. Hit the power and plug it in and that’s it, fully assembled in 5 minutes. It comes with a TINY remote that looks great but is easily lost. Definitely recommend hiding this if you have small children. Plus the MyDyson app is essential in my opinion for full functionality and it works beautifully with the Big and Quiet. Download the app by scanning the QR code, it’ll detect the Big and Quiet over BT from maybe 50!ft away but to pair it, it will tell you to place your phone close to it or pairing will fail. Once placed close, pairing is super fast and then it connects to WiFi which allows you to connect from anywhere. One of the best app integrations I’ve experienced with these smart devices. You can also connect to voice assistants like Siri, Alexa and Google and that was seamless as well. So we know it’s BIG but is it Quiet? Yes! If you manually set the speed you will hear it but it still isn’t loud, just like a gush of air. On Auto it’ll automatically ramp up if it detects poor air quality, once it’s done cleaning it will ramp down and it’s virtually inaudible. The LCD unit shows the AQ as well as a color gradient band from red (poor) yellow orange then green (good) and the speed will adjust from that. It’s great for sleeping as it’s like white noise and you can keep the air speed higher to provide a nice breeze to circulate clean air. It’s really impressive as you can feel the air from a good 20 feet away on medium speed. My wife loves it because she likes both white noise and a breeze. You can also set Night Mode which dims the display since she likes it really dark, we only wish it totally turned off the display. Lastly, you can adjust the air direction from 0, 25 and 50 degrees. The only negatives imo is there is no oscillating function, the large size and the fact it needs to be 3.5’ from a wall. My picture shows it closer before I saw that recommendation. The industrial look is subjective and growing on me and it honestly looks better than some of the similarly powerful and expensive tower style purifiers. Lastly, the filters are reasonably priced and seem easy enough to replace as the app walks you through the process which is a great touch. The carbon filter is recommended to be replaced every 2 years and the HEPA formaldehyde filter every 5 years. I treat some of these cheaper units as disposable because the filters cost almost as much as a new unit but on something like this, I’ll definitely invest in replacements. Overall this is a great air filter and circulator. Another quality device from Dyson!

Very quiet, can feel the breeze all the way across a large living room, has auto controls, will adjust filtration and fan speed automatically which is nice, unit is a good size, about 3 ft tall and 5 gallon bucket around.

It is amazing and so quiet, sometimes I forget it is there. Purification and cooling at the same time. In love with it. The app is also very useful and gives monthly reports of air quality. 100% recommended!

First time bought it and we are love it when have this in the house, this is running very quiet and feel so clean air. Thanks a lot to Dyson. Wish everyone have it .

Nice machine, quiet and very intuitive. I love the app. Shows real time air quality.

This is a quiet, large-capacity air purifier. The design is very luxurious, and the sensitive sensor works very well. I love it.

Size is big but it is very quiet and sensitive to air quality

Works good, sounds very quietly. Looks fantastic.

Love my dyson!! Works really well. Exactly what we need for my house and really quite

Air quality in my home is important to me since I have family members with breathing issues and allergies. I’ve never purchased an air purifier before because most are limited in terms of their range of effectiveness. This was particularly a concern for me because my home has an open floor plan. So the Dyson Purifier Big + Quiet Formaldehyde BP03 interested me mainly because it is a Dyson and also because it was designed for larger spaces up to 1,000 square feet. Upon arrival, the box was surprisingly large and heavy. This thing is big at nearly 33 inches tall by 17 inches wide and weighs in at a little over 26 pounds. Thankfully it’s on wheels so you can easily move it around. In the box the BP03 comes in two pieces and is accompanied only by the remote and some paperwork. The two parts snap together and then it’s just a matter of powering it on and getting the Dyson app. You just add a device. Here the Big + Quiet connects first via bluetooth and then you’re prompted to connect to your wifi network. Now you can control the unit with the app or with the remote. The advantage of the app is you can see room temperature, air quality, and humidity and filter levels. These are also visible on the lcd screen on the unit itself. You can also control it via your favorite voice assistant whether it be Alexa, Siri, or Google. Due to the size of the BP03 I found room placement a bit tricky. Dyson suggest that it should be in a corner of a room and about 3.5 feet from the wall and with the conic amplifier facing the length of the longest wall or facing diagonally across the room. The Big + Quiet comes with the HEPA and activated carbon filters installed. The HEPA filter is rated to last up to 5 years and the activated carbon filter solid should last up to 2 years. The BP03 will prompt you when it’s time to change either. I like how the Big + Quiet circulates the air as it cleans it. You can adjust the airflow speed and air direction from 0° to 50° and like the name says it is quiet. I like that the unit doesn’t just clean the air, it also monitors air quality so you know when it’s working. It also lets you know what exactly is negatively impacting your air quality whether it be particulate matter, VOCs, carbon dioxide, oxidizing gases, or formaldehyde. After only one day of use I could even tell that my home smelled noticeably better and even cleaner. I am also confident that it has helped with family members allergies. Highly recommended.

Between the seasonal pollens, Canadian wildfire smoke and our dog’s dander, keeping air quality in our home has always been a challenge….until now. The Dyson Purifier Big + Quiet Formaldehyde air purifier has changed the way we keep our air quality at its highest possible level. We’ve tried several difference air purifiers, and most did a decent job but couldn’t handle the overall interior space needing support. The Dyson Purifier Big + Quiet is certainly that, and it’s the larger size and square footage support that really sold me on this purifier. In the Box – 1 x Base Unit, 1 x HEPA H13 filter, 1 x activated carbon filter and 1 x Remote Control. Setup and user manuals can be downloaded with a QR code provided by Dyson. Unboxing & Setup – Although the size of the box is a bit daunting, setup is a breeze. Dyson has always manufactured high quality equipment and this unit is no different. It’s solidly built and looks great. The design on the Big + Quiet is different from the traditional Dyson circular air purifiers and I find this model to be much more aesthetically pleasing. It is a bigger unit for sure, but fits nicely in the corner of our kitchen/living area. The colors are a bit different, but nothing too drastic. Assembly is basically putting two pieces together, the head unit and the filter or body. It clicks together once aligned properly, pick a location, and plug it in. There is a screen on the unit and combined with the included remote control, pretty much all functionality is supported. I prefer running the app, which is easily downloaded and connection with the unit took seconds to complete. We located our unit in a corner and aimed it across the room diagonally. There are caster wheels which make for easier moving and placement. Features & Functionality – The purifier can be run on manual or automatic settings and there is a handful of adjustability in terms of the angle and power of the airflow. I’ve been running it on automatic and it’s great to know that the intelligent sensors pick up changes in the air quality and adjust the settings accordingly. One of the standouts for me is how quiet this system runs, even when the fan is set on 10. It’s far and away the most powerful and quiet air purifier I’ve owned. Settings can be adjusted with the included remote control or on the MyDyson App. The app was easy to download, and the unit connected via BT within seconds. The unit does remove formaldehyde, not sure if this is a real problem, but the piece of mind is reassuring. Filters will eventually need to be replaced, the claimed life expectancy is 5 years for the HEPA filter and 2 years for the carbon filter. They are easy to replace and are available for purchase at Best Buy, Dyson, etc. Pros: - Dyson’s top-of-the-line build quality - Ease of setup and overall unit configuration and use - Manage the unit from anywhere with MyDyson App - Large enough to support our open concept kitchen/living room area - Very quiet, even when running on higher power settings - Breeze mode is pretty cool Cons: - May be a bit large for smaller homes or apartments Overall the Dyson Purifier Big + Quiet Formaldehyde is exactly as the name implies, it’s big and quiet while keeping your home’s air quality clean and chemical, dust and odor free! I would certainly recommend this purifier to anyone looking to support a large residential or commercial space.

The Dyson Big + Quiet Formaldehyde air purifier is an impressive addition to the Dyson product line. As someone who is highly sensitive to airborne particles and allergens, I have tried many different air purifiers over the years, and I must say that this one stands out from the rest. First of all, the design is sleek and modern, as is typical of Dyson products. It seamlessly blends into any room without looking bulky or out of place. The air purifier is also surprisingly quiet, even on its highest setting. I've found that some air purifiers can be quite loud and disruptive to daily life, but the Dyson Big + Quiet Formaldehyde operates almost silently. The real selling point of this air purifier, though, is its ability to remove formaldehyde from the air. Formaldehyde is a colorless gas that is found in many household products, such as furniture, cleaning products, and even some types of insulation. It's a known carcinogen and can cause respiratory issues in some people. The Dyson Big + Quiet Formaldehyde is HIGHLY effective at removing formaldehyde from the air, which gives me peace of mind knowing that my family and I are breathing cleaner air. The only downside to this air purifier is its price. It's definitely on the higher end of the spectrum when it comes to air purifiers, but I do believe that it's worth the investment if you're someone who is sensitive to airborne particles and allergens. Plus, with its ability to remove formaldehyde from the air, it's a great investment in the long term health of your family. I highly recommend the Dyson Big + Quiet Formaldehyde air purifier. Its sleek design, quiet operation, and ability to remove formaldehyde from the air make it stand out from other air purifiers on the market. If you're in the market for an air purifier that truly delivers on its promises, the Dyson Big + Quiet Formaldehyde is definitely worth considering.

Living in the Bay Area comes with its ups and downs. One of the downsides being dirty air, especially if you have commercial areas near your home. The Dyson Purifier Big + was just what our home needed to ensure that our air was clean, and most especially, provide formaldehyde protection. This is just a bit piece of mind for the safety of my family and mine. The Dyson Purifier Big + Quiet is a good size unit that will require a bit of space in your home. But, not only does it do a great job at keeping your air clean, but it adds a touch of style to your home. The Dyson Purifier Big + Quiet is a great looking purifier (not going to lie, it reminds me of R2-D2 haha but classier haha). I placed it in one corner of my home and get lots of compliments from visitors. Many think it is a fancy surround sound system haha. The initial setup is extremely easy. you download the app, follow super easy instructions, connect to your wifi, and you are ready to go. You'll have clean air in a matter of minutes. The Dyson Purifier Big + Quiet really is quiet. Even at its highest setting of 10, its really quiet. The sound emitted is actually soothing. My wife often tells me that she likes the noise and helps her relax. The only downside to the Dyson Purifier Big + Quiet would be the cost of replacement filters. But its worth the money to keep my family safe. I would highly recommend the Dyson Purifier Big + Quiet.
