A:AnswerHi Albert, this is Kelly with Dyson. We do not make a separate base for the PH01 Pure Humidify + Cool that would allow it to be rolled around the home.
Best wishes,

A:AnswerHello Bill, this is Kelly with Dyson. We apologize for the delay in answering your question. You certainly can leave your PH01 on 24/7. If the water tank begins to run low, there is an auto-shut off, so you'd need to fill that again at that time.
Best wishes,
Kelly

A:AnswerHello there, this is Kelly with Dyson. For the whole-home benefit of purification or humidification, you would want to invest in multiple machines. The air wouldn't purify in the whole home, on multiple floors.

A:AnswerWhen my unit was working (before it broke) I had similar issues. I set the Dyson for 40 percent RH. The humidity would cycle on and off and used water. I had two other humidity sensors in the area and they never got above 36 percent RH. The Dyson though that it reached the set level. I suspect that there is a calibration issue.
A:AnswerIf you can return it. I am on my third unit and the same keeps happening. I found the part has a design defect, and I think they were fixing that. All that being said, it happened again to my third unit. Dyson makes quality stuff, but this product is sooo bad I am surprised they allowed it to go to market. It seems this happens to pretty much all of their PH01 humidifiers, so its definitely not just you.
A:AnswerHello Summer, this is Kelly with Dyson. The Dyson PH01 Pure Humidify + Cool features 10 airflow speed settings, from levels 1-10. At maximum velocity, the total airflow will be 2.2 m/s.
