Increased the room temperature
It made my room even hotter than it already was. My room was as already really hot. This made me absolutely miserable.

Super Quiet
I bought this during a smoky fire season. It works great, keeps the air clean and does so quickly and quietly.

“I’m very happy with my Dyson Purifier Big+Quiet.
“I’m very happy with my Dyson Purifier Big+Quiet. It is a high-quality product and works extremely well. The airflow is excellent, it’s surprisingly quiet, and the filtration gives me confidence that the air in my home is cleaner. I also really like the formaldehyde filtration and the large coverage area. It’s very well made, easy to use, and I’m extremely pleased with my purchase. Definitely worth it!” That also naturally includes all five suggested keywords: filtration, noise, formaldehyde, airflow, and coverage.

Useless
I bought this hoping to use it regularly. Unfortunately, it blows cold air only and I cannot see any switch to turn it to hot air. This means that I cannot use it when the weather is cold or cool, which is most of the year in Melbourne.
1 reply from Dyson Customer Service team - 29 days ago
Thank you for your review. If your machine is only producing cool airflow, and you're unable to access the heating function, we'd encourage you to contact our support team via http://ms.spr.ly/6426aHomA, so they can assist further. We appreciate you sharing your experience.

Happy with purchase
I bought this a month ago and I think its really makes a difference. I have a heavy smoker in the next store apartment and even though it really does not filter well for that smell. My VOCs are in the green so that gives me reassurance that we are not breathing in too much to much toxic poison. We run it 24/7 and the air in my apartment is great. Smells good in here all the time and my dog's coughing episodes have slowed down by 70 %.
1 reply from Dyson Customer Service team - 1 month ago
Thank you so much for sharing your wonderful experience! We are absolutely thrilled to hear that your purifier runs smoothly 24/7, keeps your VOC levels safely in the green, and has significantly reduced your dog's coughing episodes by 70%. While heavy tobacco odors from neighbouring units can be particularly stubborn to fully eliminate, we are incredibly glad that the system gives you peace of mind and keeps the air inside your apartment smelling clean and fresh every day.

Not worth the lricd
Not quite what we thought it would be. While it does filter some smells, even under duress when something is smoking in the kitchen or in an enclosed bedroom with 2 dogs, we noticed it takes the purifier a couple of hours to do the job. If cranking up the speed to 10 the noise increases significantly and for what we paid this doesn’t seem to be worth its value.

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.

Thank you for sharing feedback! It is incredible to hear how the Dyson BP03 transformed your home, eliminating the constant dust from your two long-haired German Shepherds and extending your cleaning cycle from three days to over three weeks. We appreciate you highlighting its high performance alongside the investment cost, as real-world reviews are incredibly valuable to other pet owners. Thank you for choosing Dyson!

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.
1 reply from Social team - 2 months ago
Thank you for taking the time to share your feedback. We're pleased to hear the product works well and that you've found the filter lifespan of around a year to be a benefit. We understand your concern about the filter being out of stock when it's needed, and that after waiting two weeks it is still unavailable. Having replacement parts available at the right time is important for maintaining your machine's performance. For further support and assistance, please reach out to our team via our support page: https://www.dyson.com.au/dyson-support. We'll be happy to help.

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.

크고 강력한 최고의 공기청정기!
첫 공기청정기 구매라 이것저것 많이 찾아보고 고민해봤지만, 결국 디자인 성능 다 놓칠 수 없다면 다이슨 인 것 같습니다. 무엇보다 필터 교체주기가 긴 것도 마음에 듭니다. 은근히 신경쓰이는 부분이지만 5년이라는 긴 기간이라 든든!!
