      A:  Hi Nicholas, the BP04 adds a few extra capabilities. The BP04 improves on the BP03 by adding a new CO2 sensor that indicates when an area should be ventilated. It also offers 3x the NO2 removal vs the BP03 model. The BP06 Purifies rooms up to 1000ft², evenly.² Engineered for professional environments such as offices, classrooms, and hotels.

        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.

          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.

                    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.
