Love the device. I am able to set a very comfortable atmosphere in my rooms with it. My aunt suffers from allergies, and I bought one for her as well. She loves it and is able to sleep much better at night now. She lives in an area where pollen comes down like snow.
I would recommend this to a friend!

Been using this for a while. Overall I like it. But, I have an A/C. The humidifier can keep it at 30% But 40% when the A/C is on is out of reach since the A/C condenses and remove moisture when running. Would like better control over humidity. Ei: 35%.

I really enjoy everything about my Dyson, I have changed my filters but on my little screen it is showing a green check mark with a picture of the filters, how do I change it?

Works great! The app is my only issue. When I try the app for the Dyson Purifier or the Vacuum it takes up too much bandwidth and slows the network down.

Had the unit for about a month and I can say it makes a major difference in my home environment. The air feels cleaner and my skin feels better. My dogs coat and skin has improved as well with him suffering from dry skin. Odors and dust have been reduced. The unit is relatively quite most the time until it kicks on to full power, but it is not excessivly loud. I've seen reviews about it making unusual noises. which I have heard from time to time, yet haven't had anything excessive. I believe the macine is just relatively complex, so if a seal or such is not set right, or not maintained as directed it would be the culprit. I will be buying additional units to cover the entire house in the future.
