Dyson PH01 Pure Humidify + Cool Fan

So, do not buy! I bought three consecutive units, trying my luck. The first one had white deposits around the filter housings and was continuously asked to perform cleaning. Number two would only run at max speed until stop running completely. The last one only lasted a day, emitting a burnt smell and one of the rotating air outlet units getting stuck in the closed position. Amazon took the return. I had to make three trips to UPS, and it took 2 weeks to get the funds back to my Amazon gift card account. It is ridiculous and troublesome that Amazon would not remove them from their offerings.
