Very good product
Wife has breathing issues. The air cleaner has helped significantly. Seeing the level of impunity being reduced is comforting. Removing such small particles with HEPA filter and harmful chemicals with the carbon filter makes a noticeable difference. And you can’t hear it running. It’s obvious that a lot of thought was put into the design of this product

Looks large, is large, but works extremely well
Does a good job cleaning the air and is rather quite while operating which is nice as its in the main living area of the home.

Disconnect between Dyson and pro monitoring equip
The units have hefty filters and are super quiet. The air quality readings don't match our Temtop air quality readings in the house. This is the same issue we have with our Hathaspace air cleaners. I'm guessing that there is some kind of disconnect in terminology that the Dyson/Hathaspace use and what Temtop uses. Temtop has unhealthy readings on all scales while Dyson and Hathaspace report good air quality readings in the house. The Temtop reading are in the good range for HCHO and TVOC in the house.

We’re glad to hear that your Dyson units are quiet and equipped with strong filters, but we’re sorry for the confusion around air quality readings compared to your monitor.

Your satisfaction matters to us, and we remain committed to delivering Dyson solutions that combine effective purification with ease of use. Thank you again for your input.
Extremely satisfied
I must say that so far I have enjoyed the BP04 tremendously. Easy to operate, great looking and very effective. To me this purifier is well worth the money. It is extremely quiet and the application is easy to use and very comprehensive. Happy customer here.

Really helps my breathing.
I have asthma so I have two Dyson Purifier Big+Quiet Formaldehyde BP04 that really help improve my breathing. The only problem is the new purifier that I just bought makes a ticking noice (which is a bit annoying) that my old one doesn't. I hope it isn't going to stop working. Only gave 4 stars because of ticking sound.
Customer review from Dyson
Expensive and cumbersome,
I’ve been using this consistently for a few weeks now in the hope it would alleviate my allergy symptoms and also clear food/cooking smells. It does neither! Also very large and expensive. Save your money and buy something smaller and less expensive.
