Customer Ratings & Reviews

Air quality has never been so good in the living room/kitchen area. Is quiet and filter lasts a very long time. Would highly recommend!

only drawback is the size so it works in our larger spaces. Though the larger size does allow it to move more air at a much quieter speed. The filters last much longer. Air quality in the house since deploying is so much better than before.

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.

This air purifier works really well for a big open space. I could definitely feel the difference in air quality within a short period of time running the unit. I did have to send mine back for replacement though, due to a clicking noise occuring when on Breeze mode. When this mode is on, the bottom flap on the fan oscillates up and down to simulate a breeze, but since this movement is controlled by plastic gears on the end of the flap, there's room for error if not perfectly aligned, hence the clicking noise I've been experiencing. Hopefully my replacement with Dyson rectifies this issue.

The Dyson Purifier Big + Quiet Formaldehyde BP03 has been a lifesaver for my family. It effectively removes chemical scents and perfumes that used to linger in our home — things like deodorants, air fresheners, and bathroom sprays that can be harmful to our health. What I love most is how quickly it reacts and cleans the air. You can really feel the difference — the air feels fresher, lighter, and safer to breathe. For me, this purifier isn’t just an option for households; it’s a must-have, especially if you have children. Dyson truly delivered with this one!

I appreciate having it. My Son with asthma. I didn’t even tell him or say anything. But he is not coughing in here. I put in my main room. It has a small type of smell that some people describe it last about a day then it’s all good! For me I could tell instantly. I put it on full blast for the first couple days. But then I put it on auto. And it’s been great ever since.

I love the purifier♡ Only thing I wasnt so happy about is that filters are not online or in store. You have to purchase thru Dyson and are not always instock. There are 2 filters needed per machine. I've only had for 1 year and I have to replace already. The filters are pretty pricey. I was hopeing to replace every 2yrs like it states but it was not the case. I have 3 machines and 2 of them just hit the 1yr mark and need filters. That is over 500+dlls in filters. Non smoking home, but I do have carpet. Although we dust almost daily, vacum very almost daily due to asmathic kids. Overall, it really does clean the air♡

It’s amazing, makes no noise and you can literally breath fresh clean air right away! My allergies practically disappeared.

Great purifier, with enough power to keep our second floor fresh. This has helped my wife and daughter to sleep better. I just wish the App would have a way to schedule operations (like every day or twice daily). The App provides basic operations but again, more sophisticated ones would be greatly appreciated.

I got this Dyson Purifier Big+Quiet Formaldehyde BP03 for my living room and it has been working amazingly! The purifier spreads throughout my entire living room as well as my kitchen and feels fresh all around. The product is perfect and has a sleek/modern design that fits in every living space.

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!

It's big (that's even in it's name) and expensive, but it's great. The filters last longer than any other filter system, so after a few years it actually becomes cheaper than the filter systems that don't work as well. This works! Get it.

I love this Dyson Air Purifier. It works exactly as advertised. Automatically senses changes in the air quality and increases or decreases the power. It is extremely quiet, you can barely hear it when it's running, and it seamlessly connects to the Dyson app, letting you know exactly how long the filters have left as well as the current readings of the machine. I don't have a bad thing to say.

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 .

It’s late May in Texas and the agricultural burning down south has made the air difficult to breathe. My apartment sits on a hill and negative pressure slowly drew the outdoor air inside — making an indoor smog that I could visibly see with a flashlight. Two hours with the Dyson purifier and I’m breathing better than normal. I can’t recommend this product enough. It’s outstanding.

Product does exactly what I need it to do. Air quality in house has improved.

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

It's a great machine, hates hand sanitizer. The only problem I have had is that I went to move it and two (out of 5) of the wheel castors were broken off and they cannot be replaced. I have no idea how it could have even happened unless there was a defect, the castor itself is flawless except where it should be attached to the machine. Luckily, the 3 wheels left are evenly spaced and it is still level and rolls now that I took the broken ones from their slots.
