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.

Incredible product, supper recommended. I can control it from phone and will clean any smells even smoke in the room.

I have severe allergies and this has helped somewhat. It’s a really good product. Very easy to put together. I love the app and the real time readout of the air quality. This is a great buy, especially if you get it on sale!

Amazing air purifier helps prevent asthma attacks for people with severe asthma and chemical sensitivity. Has a five year filter also. The customer service agents in the store were very kind and helpful at Best Buy of Woodland Park NJ.

Purchased for my living room Does a great job and stays really quiet. Bonus points for looking nice Only con is price but it was definitely worth it

I love this air purifier. I bought one for me and it makes my room feel so fresh and clean all the time. Easy to set up and I actually came back and bought one for my mom. It is such a great gift to appreciate Mother’s Day. Big fan of Dyson again ❤️

This air purifier has made a difference in our home after finally deciding to do something about the air inside looking like something was burnt. I can see the difference it’s made in our main floor of our home after buying this Dyson air purifier. It’s been a few weeks since we had it but it works.

For the price, this really feels like a $500-$700 purifier not an almost $1100 one. I didnt really like the whole plastic body parts it had it just made it feel super cheap. Over the first few days I think the filter was "breaking in" and it had this weird spice smell coming out of it. Overall its been doing a good job, I tested this out by leaving the air purifier in one room at max speed, closing it and coming back at the end of the day. If you go to another one and go back to the air purified one you can tell automatically the difference. This is the closest I can describe it to, the air after it rains for a while. Overall its a great purifier but for the price I was expecting a ton more at least a cooling option.

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

Been a big help with allergens in the air my son has never slept better.

My roommate is a chain smoker. I swear, this machine keeps up with her smoking. It cleans the air when she's at work and through the night. Making my days and nights breathable.

Disappointed given SOOO expensive. Filter works great, but three of the 5 wheels on this unit BROKE OFF just over a year after purchasing. No response from Dyson when emailed months ago. We just move it a few feet back & forth on wood floor between 2 rooms - no kids/ dogs, no trauma (other than whatever happened before shipped / arrived). Plus, have to replace expensive filters relatively frequently if you keep it running full time.

Product is working very well. The air quality in my home is noticeably better.

This Dyson air cleaner, as its name clearly states, is both Big and Quiet. Like its smaller siblings, this one works well but is designed for spaces where the smaller models would struggle. It is quite imposing on the floor but fills even the largest of spaces with purified air. Even at the highest fan speed, it’s still quiet enough to enjoy a movie or quiet conversation in the same room. The built-in display provides useful information and the wifi connectivity and app integration provides convenient control and detailed historical data. Pros: * Exceedingly quiet even at the fastest fan speed. * Automatic mode is suitable for nearly all situations. * Works well for larger spaces like a great room or a home with an open floor plan. * Hidden wheels allow for easy relocation or aiming. * Convenient remote control that stores on the unit. * Useful app integration for control and data. * Long-life filters with easy replacement. Cons: * Large. * Requires floor space (not for mounting on a table). * Not inexpensive. Like most other Dyson air cleaners, this one works very well at keeping the air in your interior spaces clean and free from harmful pollutants. True to its name, this one’s main benefits are being both big and quiet. It is intended to be used in larger interior spaces like an open floorpan home or a large home with huge rooms. There are hidden wheels to allow you to move it around or spin it easily, and the Dyson app provides full connectivity and data from anywhere. While it looks like the top portion might swivel or rotate, it does not. Instead, the vertical angle of the air stream can be adjusted via the app to either project out closer to the middle of the room, or up toward the ceiling to reach further. Setup was easy as usual for Dyson. It essentially came as two parts plus the remote control. The “dome” portion just snaps onto the top of the main unit, then plug it in and connect it the app. The filters were pre-installed and everything started up smoothly. The app makes it easy to change settings, register it for the warranty and start getting air quality and filter status data. Once you find a good location for it, it will basically continue to run unattended; silently cleaning the air, until the filters need replacement after about 2 years of normal use. The main settings are the fan speed and the air output angle. I have mine set for automatic fan speed and the air tilt set to randomly change angles to create a breeze effect. It is placed in the corner of a great room that includes 3 open concept smaller rooms and it easily reaches everywhere. Overall, the main reason to select this Dyson air cleaner instead of its smaller sibling models is its ability to sustain clean air in large spaces without the need for loud fans and exceedingly strong air movement. Provided your needs allow for its size and price, this unit will exceed at keeping your air as clean as possible for years to come.

Quiet and efficient, even when I spray cleaning solutions it quickly turns on to take the smell out

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 Large but super powerful! I have many air purifiers and this Dyson is the best by far. I suffer from lots of allergies which are worse in spring and summer. We also have two dogs that shed constantly and require us to vacuum almost daily. I'm currently running three air purifiers in my house, one in the bedroom, basement, and main living area. My prior main living area air purifier tried to keep up but would struggle. It also had an auto setting to adjust fan speed. When the fan was on high it was super loud and distracting but was needed because our air quality wasn't the greatest. This Dyson is the total opposite when on auto. When the fan is on high you can barely hear it running. This is great as its less intrusive in our living area. Since placing this in our main living area I have found that I can actually breath in our home. I usually have one nostril plugged up or sneezing from particles in the air. With the Dyson I no longer suffer from those issues and can actually breath way better. Since now I can breathe, I have been sleeping way better and no longer waking up exhausted or congested. This thing works so well that I can overlook the odd colors or large size since it does what it needs to do better than the competitors. Keep in mind this machine is large almost three times the size of our older unit. Thankfully we have a big enough space that we can place this air purifier without it being in the way. It also has wheel casters so you can easily move it around if needed. Some friends saw it and really liked the features and how clean our air was but said it would probably be too big for their condo or townhome. So, keep that in mind if you are looking to purchase this Dyson. The remote is magnetized and sticks to the bluesish housing (remote is the gold bar), which is nice, so you don't loose it. I also think the color combination is a little strange, silver, gold and bluish purple. Honestly wish they would have done just silver and blue or just kept it simple like black and white. It doesn't really blend in with our decor due to these colors, but I don't care as the air purifier made a huge improvement in our house. You can connect this air purifier to your internet and use the Dyson app to make changes or review air quality. If you do not wish to connect to your internet, you can use the display on the unit to get the same information. My prior machine did not connect to any app and the display did show each type of air pollutant, but I had to look up what they were. This Dyson has a guide printed on it (on the silver dome part) saying what each air pollutant is, which I find helpful so I can made adjustments in my home. The Dyson also shows air temp along with humidity, these are also very important to air quality. It seems like Dyson spared no expense and wants you to know everything you are breathing in. I liked that you can also adjust the fan angle to help keep the air circulating in your home, instead of just shooting straight up or straight forward like other units. I have a feeling that the air filters will be expensive to replace as all of my current ones are as well. The filters seem to have a long life and should hopefully last a full year. Once they are done, I will gladly replace them as this machine replaces all of my other air purifiers. If you suffer from allergies or poor air quality this is the one to get!

man man man. lemme tell you i got two cats that live in a ROOM with me and when i tell you this takes away the smell is an understatement. this thing not only takes the smell away but it also makes the room very easy to breathe still. i know you guys know that stuffy air im talking about. this thing is crazy and this is the definition of an investment cause ive tried so many $100+ purifiers and theyre butt compared to this. cat man approved

I've never left a review on Best Buy before but I felt like I had to for this one. This Dyson Big+Quiet is the BEST purifier they have ever made. And that's coming from someone who's owned the TP02, TP07, TP09, and now this (with some other brand air purifiers in between). As the name implies, it's quite large and in charge. Unlike the tower air purifiers from Dyson, there's no compromises here — it doesn't have to also function as a fan with oscillation. It was designed to just do one thing well: clean the **** out of your air. And it does it well.

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.
