Details & care
Dyson's biggest purifier yet, it's engineered from the ground up, to evenly purify large spaces.*
What it does: Cone aerodynamics creates a condensed jet of air to project purified air over 32 feet. Quietly. An advanced 360 HEPA H13 grade filter captures allergens and 99.97% of fine particles. It removes gases and odors and destroys formaldehyde, permanently.**
Additional features: Use the MyDyson app to control and monitor your air quality from anywhere, and program your machine to turn off after preset intervals, between 30 minutes and 8 hours. The filter is 3.8-times larger than the previous generation and lasts up to 5 years. Breeze mode recreates the feeling of natural air indoors. Do not disturb mode monitors and purifies using the quietest settings, with a dimmed display.
Includes: Purifier, HEPA filter, activated-carbon filter, remote control

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

Replacing Big+quiet with Hot additional feature
I liked this product but missing the hot air flow in the winter. What are the options to replace this with the one having all these features plus the hot air?

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.
