    Cannot ever go wrong with a Dyson. The humidifier function is great and they’ve made it super easy to add water to the tank. I use distilled water even though the manual says tsp water will do. One full tank lasts 3 nights.

    Life saver for those of us who live in colder climate areas. Heater on tends to dry out our house and create a stale smell but this Dyson has changed all that. It’s expensive but well worth

    Very good upgrade from previous PH01 models. The PH01 seem to have some problems with the pumping mechanism that was fixed with the PH03 and PH04. Overall very happy with purchase. Easy to set up in app and connect to home wifi. We have 6 Dyson machines around the house all working very well together.

    It’s been a good purifier and humidifier but you really need to be gentle and loading the water tank cause if it’s a little off it won’t work
