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?

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 - 24 days 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.

Not good at removing VOC
Not so good at removing VOC. Leave it on for the whole night but VOC still not zero

Run don’t walk!
Beautiful, easy to assemble, at first I kept checking the units to see if they were on because they are so quiet! I have research air purifiers for some time. These machines are top of the line. They are a great help living in the unhealthy air in Dallas area!

The Best Purifier
The Dyson Purifier has worked a treat in helping to reduce smell from the house from cooking to removing harmful allergens. Usually during winter time, my family would get cold and cough easily, and with Dyson purifier continuously cleaning and purifying the air, my family is sick less often.

Smelly Carbon Filter
Negatives: Carbon filter smells. I’m worried it’s introducing toxins to environment. Sweet syrup like smell that doesn’t go away. Positives: The most quiet purifier I’ve ever used. Max speed on dyson is same DB as medium to low speed on other brands.
1 reply from Rubaid K team - 9 months ago

Life-Changing Air Purifier
This air purifier has been nothing short of life-changing. I have struggled with sleep for over 20 years. I wake up in the middle of the night and can' go back to sleep. I haven't awoken feeling refreshed and energized in that many years either. I've tried allergy testing, sleep studies, other air purifiers, weighted blankets, cooling blankets, supplements, sleeping alone and nothing has worked that well... until now. I have no idea why/how Dyson has the magic formula, but all I can say is that I went from 9-15 minutes of deep sleep a night to 60-80 minutes, and I've had "Dyson" less than a month. I've experimented with the included fan capabilities and found that I like 0 degrees the best (which essentially blows right at bed level). It is whisper quiet (I keep it at level 3 and seriously BARELY know it's on and it's only a few feet from me due to the layout of our bedroom). I like the Alexa capability because I'll turn it on from the kitchen before I go to bed to allow the air to be cleaned as I wind down. I love the app that shows the allergen, particulate matter, VOC levels and I love to watch how quickly those levels lower when my new best friend, Dyson, is turned on. While it is gigantic, I would wholeheartedly recommend to anyone looking for a fantastic air purification system and possibly a miracle sleep aid for you!
