    It's Meh...especially for the price.

    While I believe the air is more humidified with this device, I'm disappointed that the unit doesn't work as a fan when the water has run out (or if you just wanted to use it as a purifier/fan during months you may not need humidity). I also find that it cycles through water very quickly. For the price of the unit it is a little underwhelming.

    Expensive piece of junk

    Absolutely disappointed with this product. It ran for about 2.5 months and started having issues. The screen and the app will tell you to run a deep cycle, right after a deep cycle. Another issue was the pump column. Too bad it was outside the return window from best buy so I couldn’t return or exchange it.

    I'm quite pleased with this item. We generally just leave it on the "auto" setting and carry on as usual. I like to have the ability to monitor our air quality, which incidentally gets pretty terrible when we cook--useful information.

    Quiet, and moves a lot of air! Love being able to use the app to check conditions in the house. We have it in the Master for my wife, her hacking at night and in the morning has gone away. Yet to know if the humidity part is really working.

    This significantly improved me and my partners sleep quality, it can be very quiet but we actually like the very low white noise it produces. I love the humidifying option it has because with one purchase you can get 2 things out of the best item

    Although the price is very expensive, we have found the machine to be well worth it. The breathing in our household has improved significantly. We have a family of four that used to wake up stuffy every morning and congested almost daily. Since we purchased these machines a little over a month ago we are all breathing better. We’ve been able to eliminate our allergy medication. Highly recommend. We have one on our main level and one on our lower level of our house.

    Holy wow, quiet, beautiful, the cleanest of all air i've ever slept in. I am however having a small issue where it keeps randomly turning off and disconnecting from the app which is a bit odd since i'm only about 3 weeks into use, the problem is fixed once I unplug and replug it into the wall.

    We’ve had the Dyson now for about a month and have zero complaints. The app works great with giving us data on our air quality for the room. It’s not silent but the sound it gives off when running is very minimal.

    This definitely came in handy when New York was covered in smug from the Canadian wildfires. It’s also very useful for people with allergies or live around areas where dust and allergens are an issue.
