Great product
"I’ve been using this purifier for a few weeks and absolutely love it! The auto-mode is incredibly smart, adjusting the airflow automatically after detecting odors or cooking smoke in the kitchen. It runs so quietly. I also really enjoy tracking the air quality metrics in real-time using the MyDyson app. Highly recommend it!"

Great for households with long-haired dogs!
Absolutely phenomenal; changed our lives for the better! We have had our 2 long-haired German Shepherds for three years. Since then, the counters and the bookshelves in our house have been constantly covered in dust. We couldn’t go 3 days without a top-to-bottom dust job. To really test the Dyson BP03 air purifier’s effectiveness, we did a top-to-bottom clean (everything: baseboards, books, bookshelves, counters, etc.) and turned on the air purifier (running 24x7). Three weeks later? No dust! The counters are still clean! No dust on our books or bookshelves! This purifier is unbelievable! I can’t recommend it highly enough! Yes, it’s pricey; but if you have long-haired dogs, you cannot live without this.

Great product, low/no filter replacement in stock
Works well. Filter lasts a year. Would be full marks but the filter is out of stock when you need it. Have been waiting two weeks for it to come back into stock and it still is out.

Good but no use in my house
The product is good and did everything it said in the advertisement. Very quiet at night, too. Delivery was very quick and smooth as well. The only problem is that I probably do not need it. The air in my room in my location is very good. The monitor always have nearly 0 reading in all microscopic particles. I guess this product is good for home in dusty environment like some construction nearby or have animals at home. At the moment, it is just sitting there as a decoration in my bedroom. This product deserves 5 stars, one star off just because I don't need this.

I think it’s working but not sure
I have no way of quantifying how well or how bad this purifier is working. The AI Buzzwords suggest I can tell how efficiently it works. It’s slightly loud and has a filter. Thats about all I can say.

Replacing Big+quiet with Hot additional feature

Very poor performance considering there are 5 unit
I purchased 5 of these units and wont keep the VOC low ,looking at returning
1 reply from Dyson Australia team - 3 months ago
Thanks for your review. Buying five units is a big investment, so it’s understandably disappointing when they’re not keeping VOC levels as low as expected. Your feedback is valuable, Hopefully the issue can be resolved so the units deliver the level of purification you were expecting. Feel free to reach out to customer care so we can look into this for you. https://www.dyson.com.au/dyson-support

Great investment for your families health
I purchased this a month ago and I have no concerns. I enjoy the fact it has wheels so it can be wheeled wherever whenever. Some say that the noise is quite loud; I’m not hearing anything more than what you would hear from a regular fan. The directions included state to change the filter once a year, so that is really appreciative when you have a busy life. I’ve noticed it handles dust well in our apartment. It will be interesting to see how well it filters out the smoke from the forest fires this season. Overall, I feel it was a good investment. If anything, the magnet strip on the back to hold the remote could be a bit stronger, but I feel mentioning that is petty for the overall effect of the machine.

Great product.
Initially I had my doubts about whether I had made a good purchase but after a week of use I am very happy with this purifier. It is very quiet and super sensitive. Just putting a piece of bread in the toaster is enuf to activate the purifier from idle to mid range and it is in the other room and about 30 feet away from the toaster. Same with my gas range , it picks it up right away (NO3) . My rottweiler sheds alot and sleeps on the couch (or where ever she wants) and the air quality is definitely much better. Highly recommend this product.

Silent Fume Eater
Effective. Clear the air very well. Managed to get a good sleep in my freshly painted room with the Dyson running.Worked silently. Would be better if it occupied a smaller footprint. Would rate 5 stars if the price is more friendly.

Thank you for your review, it’s great to hear the purifier is working effectively for you, especially in a freshly painted room, and that the quiet performance stands out. Noting the footprint and price point is helpful feedback for future improvements.

Only had for two weeks but my old purifier (airomaid) dies after 12 years. Noticed the difference so tried the Dyson - very very happy so far.

Nice but ....
Bought this last month, and it works nicely for air purification, but the air movement is undersized for the room to keep it on auto mode, so we run it at 10 almost all the time, which takes the super quiet nature off the table. The temperature is off by 4-5 degrees F as I read in other reviews before buying, not a big deal but bothersome and why? The app is good.

Live in an older home that which means plenty of dust. This unit does a great job of reducing it.
