Clean, purified and humidified Air!
I am very happy with the Dyson Purifier and Humidifier. It's efficient, works well (is not as loud as I thought and read in reviews), the Dyson app works very well just wish it had more explanations for each category recording but may have to do a bit more research. When air quality drops, I turn it on (purifier and humidifier) at the same time and it doesn't take very long to purify the home. The water tank is large and holds enough to last for a while, I'd say about a week for decent daily usage. The design is a bit bulky but it's an amazing machine that keeps our home clean and purified. I'm very happy with my purchase. In my opinion, worth the expensive price tag.

Game Changer
This machine is one of the best additions to our home we have ever made! The air feels crisp and clean. The humidity is perfect and it has the design quality you would expect from Dyson. From someone who has terrible seasonal (all seasons;) allergies, this is a game changer. I would highly recommend!

Happy
Just be aware that it is not a heavy jumbo humidifier. And for max moisture production, you must max out the fan - not the quietest thing. Purification is a nice plus, but I already had 2 other purifiers. My air is very clean. You will appreciate the very low maintenance. Most other options require complete cleaning every few days - yuck! And if you don't give them a good scrub every few days, you will be shooting slime, gookus, and bacteria into your air. The Dyson stays clean as a whistle - very nice. Very happy with my purchase.
Hi, thank you for sharing your experience with us. We’re glad to hear that you’re enjoying your machine and that the low‑maintenance design has been such a helpful change compared to other humidifiers. It’s great to know the purification feature and overall performance have made a positive difference in your home. We truly appreciate your thoughtful feedback and are happy to hear you’re very pleased with your purchase.
