Great
I’ve had mine for 3 years now and it’s been great. It humidifies, is a fan and air purifier. I’m in NYC, so when the Canadian wildfire smoke came here recently, this came in so handy. The only downside is how much the filters cost.

Great, but ...
I brought this device last month. It has been amazing so far, but the only issue I have is that a few weeks ago it started to give off a weird smell whenever I would put on the cool function. I don't know how or why; it was fine when I first started using it. Other than that it would definitely be a 5/5.

Excellent product
Since purchasing the PH03 Humidifier, it has been used every day/night and appears to be living up to the claimed results. It is quiet, attractive and the water is easy to change. Part of the proof of the pudding - so to speak - will be in the Ease pf the cleaning process. So far, it was an excellent buy.

A Must Have
The cooling, coverage, FILTRATION, HUMIDIFICATION, and quietness are great. Less dusting, and no more dust allergies. Have purchased several tower fans, which always broke. Cheap is expensive. The costs added up. Dyson Fan is 2nd to None.
