Customer Ratings & Reviews

Works very well but there is nothing on it or what its made from that can justify $1000. Legit a fan that sucks air into a filter, after this purchase i will never complain about apple products and their mark ups because they seem like a bargain to me now.

Works great! I love that you can control from the mobile device

Very quiet and worth the money. My advise, spend the extra $100 and get the best model.

Easy to use and very convenient to see what’s dirty in the air. But not sure how effective it actually is.

What a difference. Yes, it does s worth the extra money spent up front. You can go cheaper. But, are you getting your value when you add in filter replacement. The Dyson and s every FIVE years.

Love the quiet as well as the efficiency of the product. Will be buying another one for upstairs as well.

Love the features but doesn't seem worth the price. It's also quite ugly so we end up trying to find a corner to hide it in.

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.

Been a long term Dyson user. They're expensive but seriously impressive. We bought their vacuum as well and never looked back. They're brilliant when it comes to innovation. Keep pushing the envelope.

Before purchasing, had trouble breathing and coughing on a continual basis. With the Dyson Big & Quiet, I have found my breathing is better and coughing is a lot less noticeable.

Its A Really good machine I use it for my room which is probably over kill but it does this annoying rattling noise when you have it on Low settings. I already filed an exchange and Waiting for my new one I Will post an update if it still makes the noise when the new one comes in that way well know if its just part of machine or not

Bought two. One is noisier than the other one. The remote looks cheap and bad. Good packaging, buggy app.

Excellent product and performance. Whatever we expected we got all.

Excellent for dog owners! Totally worth the price.

Innovative technology. Smart, Works Great, YOU GET WHAT YOU PAY FOR SOMETIMES

Excellent for large room. App is very good as well.

Works great. I like the look and sound. Easy to use

So if you do the math these units on paper should do a really good job overtime. The problem is their customer support does not stand behind their product. Mine started making a loud idling fan noise and they wanted me to ship it off and be without an air purifier for up to a month and some change. Yeah just get a different device.

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.

I wanted to like this air purifier, but it released a sweet smell that was overwhelming if left running for a while. I ran it for many hours hoping it would diminish after some time, but it did not. I did not take notice of complaints like this, but they do exist. Check them out before buying, generally referred to as a “sweet yeast” smell. I ended up returning this.
